Finally a brightness How To for Vaio FW Series

with 228 comments

WARN: This how to is only for laptops with Ati graphics. Do not apply any changes to DSDT if you have Intel graphics.

WARN: Remember, when you update your kernel, you should remake all this again for new kernel.

WARN: DSDT update cause kernel panic during boot on 64bit kernels <= 2.6.27-9. Use noacpi option in grub to boot without DSDT.

UPD: S1/AV mode keys are enabled in new patch for sony-laptop module.

Hello there guys. Long time no updates, and here is a big one )

Thanks to Anze for pointing me to 11682 bug. I have managed to make easy howto on enabling brightness control.

First of all we need to install iasl and acpidump:


sudo apt-get install acpidump iasl

Second, download my patches (alternate link). And unpack it somewhere. Then go into that directory in your terminal.

Third, we need to patch our default DSDT table:

UPD: If you have Sony Vaio FW2xx or FW2x models, please use dsdt-error-fw21.patch and dsdt-ati-fix-fw21.patch here.

UPD: If you have Sony Vaio FW3xx or FW3x models, use dsdt-error-fw21.patch then dsdt-error.patch and then dsdt-ati-fix-fw21.patch here.

sudo acpidump -b -t DSDT -o DSDT.aml
iasl -d DSDT.aml
sudo rm DSDT.aml
patch < dsdt-error.patch
patch < dsdt-ati-fix.patch
iasl DSDT.dsl
sudo cp DSDT.aml /etc/initramfs-tools/
sudo dpkg-reconfigure linux-image-`uname -r`

Here we dumped our DSDT table and then decompilled it. Then patched with dsdt-error.patch, this patch fix wrong name (“_T_0″) produced by disassembler. Without this patch we can not recompile this table back. Then we patch with dsdt-ati-fix.patch, this is the actual fix made by Zhang Rui from bugzilla, and recompile table back. And then we put our patched DSDT into initramfs, to allow kernel load it instead of original DSDT.

Fourth, we need to patch sony-laptop module to make our Fn keys for brightness work correctly:

UPD: If you have Jaunty kernel version >= 2.6.28-11.36, do not do this step, this patch is included already.

Install kernel source and all packages needed for compiling it (who knows a better way to not download so many packages by build-dep? or build-essential is enough).

sudo apt-get build-dep linux-source-2.6.27
sudo apt-get install linux-source-2.6.27
cp /usr/src/linux-source-2.6.27.tar.bz2 ./
tar jxvf linux-source-2.6.27.tar.bz2
cd linux-source-2.6.27

Then put here (linux-source-2.6.27) sony-laptop.patch patch and make this:

patch -p0 < sony-laptop.patch
cd drivers/misc/
make -C /lib/modules/`uname -r`/build/ M=`pwd` modules
strip --strip-debug sony-laptop.ko
sudo install -m644 -b sony-laptop.ko /lib/modules/`uname -r`/kernel/drivers/misc

This will compile and install our new patched sony-laptop module.

Now we need to reboot.

After rebooting we can check if all ok:

dmesg | grep -i sony-laptop
dmesg | grep -i dsdt

We should get something like this:

[   16.045201] sony-laptop: Sony Notebook Control Driver v0.6.
[   16.190130] sony-laptop: detected Sony Vaio FW Series

and this:

[    0.000000] ACPI: DSDT BFE06010, 8016 (r1   Sony     VAIO 20080605 INTL 20051117)
[    0.044471] ACPI: Checking initramfs for custom DSDT
[    0.359780] ACPI: Found DSDT in DSDT.aml.
[    0.359785] ACPI: Override [DSDT-    VAIO], this is unsafe: tainting kernel
[    0.359793] ACPI: Table DSDT replaced by host OS

Now try to use Fn brightness keys. This should work =)

  2. Hi, gave this a go on my FW21E. Unfortunately the first patch failed to apply:

    patching file DSDT.dsl
    Hunk #1 FAILED at 8226.
    1 out of 1 hunk FAILED — saving rejects to file DSDT.dsl.rej

    Any ideas what might be wrong?

    • Try the second patch dsdt-ati-fix.patch, your DSDT maybe do not need the first one. If this fail too, send me your DSDT.dsl.

  3. The second patch applied ok, but the recompile stage failed. I tried doing a Find & Replace on _T_0 in my DSDT.dsl file. This allowed me to do the recompile and I completed the rest of the steps.

    Unfortunately, although the gnome brightness display moves when I press the Fn keys the screen brightness does not actually appear to change.

    And show the output of find /proc/acpi/video

  8. Seems fine too. Do you use fglrx driver?
    You can upload files onto filefactory.com or another site like this and post links here.

    egaistek

    December 7, 2008 at 05:55

  9. Egaistek, I can’t thank you enough! I tried this out and it works beautifully. The only issue I am having is that my ‘brightness +’ key is missmapped somewhere and doesn’t work. The ‘brightness -’ works perfectly. I just need to figure out how to reset the keymapping for KDE.
    Oh well, I can still use guidance power manager or the console to adjust brightness in the mean time.

    Again, Thank you

  10. yeah, finally the brightness works on my vaio FW11M. thanks, Egaistek!

  11. Tamagotono, I’m not using KDE, so dunno what’s wrong there with keys. I thought if you patch sony-laptop module, KDE will understand it like Gnome did =)

    “The second patch applied ok, but the recompile stage failed. I tried doing a Find & Replace on _T_0 in my DSDT.dsl file. This allowed me to do the recompile and I completed the rest of the steps.”

    the recompile failed how and what do I find and replace to get it to recompile? Thank you in advance.

  16. Egaistek, Your patch works just like it should. When I run xev I can see that the keys are returning unique keycodes, but they are mapped to “XF86STOP” and “XF86FORWARD” I have a feeling it is one of the remaining bugs in KDE4.1. I have been able to map other keys to do the same function, so I am able to get by until I figure out the proper fix.

    Again, thank you!

  17. Hi,

    Thanks I managed to change the brightness from my laptop!!

    The only problem is that amount is not saved when I shut down and I have to scroll brightness down each time I reboot my computer… do you know how could I fix this?

    Thanks,

    josepcoves

    December 9, 2008 at 05:00

  18. josepcoves, brightness is set to default value after reboot, you can change it in power management preferences (right click on battery in tray).
    I guess we can save last set value and then restore it after reboot with scripts etc, I’ll think about it then.

    dwade, if the first patch not work for you, which laptop model do you have? the same is Joc have?

    Tamagotono, yea, seems bug somewhere, because Gnome see this keys as XF86MonBrightnessUp/Down.

    Joc, I’ll see what I can do.

    egaistek

    December 9, 2008 at 05:40

  19. Excellent! Workd like a charm!

    One thing though. I know it’s a miles of work but… I would love to see this packaged in proper patch form. Command line would even be nice and some simple graphical version would be awesome and would really help the people who are just stumbling into the world of Ubuntu and happen to have VAIO in front of them. Let’s face it, for normal user, command line is something rather scary. Hell, I wouldn’t want to use it myself either.

  20. Egaistek, Joc:
    I`m also having Sony Vaio FW Series Notebook… VGN-FW21M exactly. For me also first patch doesn’t work. It ends with the same error message like Joc’s… Is there any possibility to handle that?

    mike

    December 9, 2008 at 22:40

  21. Hi egaistek thanks for your answer, but I cannot find anywhere under managment preferences to store brightness… how would you do it using scripts?
    I found this but doesn’t work:

    sudo spicctrl –setbrightness=10

    Thanks

    Thanks anyway.

    December 10, 2008 at 05:46

  24. Giorgos, I am running Kubuntu and it is working fine on my VGN-FW139E/H laptop. The keys do not map properly but you can still use the slider in guidance-power-manager to adjust it.

  26. Hi all

    I’ve tried also, on a fw21z, same error has Joc, I stopped there.
    quick tip for those in my case, and using compiz, in the module “opacity, brightness and saturating”, you can configure to lower the brightness a little of all windows, menus… It helps a lot the eyes, if not the battery

    Thanks anyway Egaistek for all this work, very useful

    echo 1 > /sys/class/backlight/acpi_video0/brightness
    

    Does brightness change?

    P.S. Do not do sudo echo this will not work.

    egaistek

    December 12, 2008 at 05:50

  32. Nirgal this seems you have no sony-laptop module loaded, do this and check dmesg then:

    sudo modprobe -r sony-laptop
    sudo modprobe sony-laptop
    

    egaistek

    December 12, 2008 at 05:57

  33. Mikko Tikkanen, about the packaging. Well you see that there is problems with different bios versions etc. We can contact sony-laptop author to update it with patch, but again, this patch without patching DSDT is almost nothing. But again we can write shell script which can check bios/model version with dmidecode --type system and download needed packages/sources for compiling. If you want to help, let’s try =)

    egaistek

    December 12, 2008 at 06:02

  34. Why does sony-laptop.ko not exist for me? I find it rather strange. Please help as I’m rather intimidated by command lines

    ScopeJim

    December 12, 2008 at 14:47

  35. Egaistek : I had not answer from the terminal when doing those commands, and same error after
    Is it possible that the sony-laptop module isn’t installed ?
    I wasn’t able to find anything about this module
    I’ll try later to do a second time the whole thing to see if anything changes

    Nirgal

    December 12, 2008 at 22:44

  36. You can check if it’s installed or not by:

    modinfo sony-laptop
    

    Or you can load Ubuntu live cd and check it there. Maybe you did something wrong with your system, because it should be installed by default.

    egaistek

    December 13, 2008 at 01:07

  37. Nirgal, there should not be any output, check dmesg | grep -i sony-laptop after that commands.

    egaistek

    December 13, 2008 at 01:09

  38. Thanks for the help. I figured I hadn’t installed the linux-source properly. Do you have a forum to visit btw or just the Ubuntu forums?

  39. I’m on Ubuntu forums, but I have not any threads there.

  40. I have tried your new patches and everything applies fine but brightness still does not change.

    Applying the two echo commands in your post above DOES reduce the brightness of my screen.

    How should i go about revert the brightness of the screen?

    Joc

    December 13, 2008 at 03:04

  41. Now try to delete patched DSDT.aml from /etc/initramfs-tools/ and reconfigure kernel by:

    sudo rm /etc/initramfs-tools/DSDT.aml
    sudo dpkg-reconfigure linux-image-`uname -r`
    

    Then reboot and try that echo commands again, does it change brightness again?

    To revert back use echo 8 instead of echo 1

    8 is highest brightness, 1 is lowest.

    egaistek

    December 13, 2008 at 03:13

  42. Nope, no change in brightness this time. There also does not appear to be a /sys/class/backlight/acpi_video1 directory.

    Joc

    December 13, 2008 at 03:37

  43. Does brightness changed when you echoed in acpi_video0 or acpi_video1 the first time?

    egaistek

    December 13, 2008 at 05:27

  44. Can you try to compile this DSDT and show output of this commands:

    find /proc/acpi/video
    find /sys/class/backlight
    

    and try this:

    sudo su
    echo 16 > /proc/acpi/video/VGA/LCD/brightness
    echo 8 > /sys/class/backlight/acpi_video0/brightness
    exit
    

    If this change brightness, you can try Fn keys and slider in power manager.

    egaistek

    December 13, 2008 at 05:54

  45. the modinfo return me this
    “filename: /lib/modules/2.6.27-9-generic/kernel/drivers/misc/sony-laptop.ko
    depends:
    vermagic: 2.6.27-9-generic SMP mod_unload modversions 586″
    so the sony-laptop seems to be installed
    after the two commands before (modprode) I have still the same error for “dmesg | grep -i sony-laptop”

    The Fn’s and gnome brightness applet do not work, but when doing the echo commands the brightness is changing

  50. Great! I’ll change patches for 2x models then.

    Nirgal, are you sure you have patched sony-laptop? Update your kernel to the latest version 2.6.27-10 and remake 4 step from how to.

    and I update my system, not new kernel. Is it in the backports ?
    I try to remake it with my kernel

    When using Fn brightness keys, do you see brightness osd?

  62. Hi Egaistek…

    Unbeliveable but I don’t have that slice bar on startup… my configuration window ends at “Put display to sleep at inactive”. I’m using Hardy maybe that one only appers in Intrepid, could it be?

    Thanks

    December 15, 2008 at 14:17

  63. For myself with last update the brightness keys aren’t working, but the gnome applet is working perfectly, and the default brigness in power management to.

    the results from the dmesg | grep -i sony-laptop aren’t the good ones, I m not at home, but I remember I had first time something like this:
    [ 11.177295] sony-laptop: Sony Notebook Control Driver v0.6.
    [ 20.642880] sonypi: please try the sony-laptop module instead and report failures, see also http://www.linux.it/~malattia/wiki/index.php/Sony_drivers

    and I tried to do the how to again and now I have something like this:
    [ 20.642880] sonypi: please try the sony-laptop module instead and report failures, see also http://www.linux.it/~malattia/wiki/index.php/Sony_drivers

    well I can change brightness with the gnome applet so I m happy !!

    Nirgal

    December 15, 2008 at 15:18

  64. josepcoves, yep maybe.

    Nirgal, well again, in this comment you have patched sony-laptop right because you saw brightness osd, now you forgot to patch it or I don’t know. Last update touch only DSDT and not sony-laptop. Remake the 4th step again.

    egaistek

    December 15, 2008 at 23:16

  65. SOME SUCCESS….

    This command dims the screen.

    echo 1 > /sys/class/backlight/acpi_video0/brightness

    but I still do not have control of either the FN keys or in power managment.. Thank you for this bit of hope, what do I do next?

    dwade

    December 16, 2008 at 05:11

  66. dwade ok, now delete patched DSDT make dpkg-reconfigure like in 3rd step, reboot and try echo commands again.

    I see that sony-laptop module is loaded at you and detected fw series, but I don’t understand why fn keys not work. Does sound change when you use volume keys? Do you see sound osd while changing? Does osd like with sound pop up when using fn brightness keys?

    If not, do this:

    sudo modprobe -r sony_laptop
    sudo modprobe sony_laptop debug=1
    

    then push Fn+F5 and Fn+F6 and do this command:

    dmesg | tail -40
    

    Then post the output to this site http://pastebin.com/ and give me a link.

    egaistek

    December 16, 2008 at 05:44

  67. maybe I do something wrong, I did this….

    # sudo acpidump -b -t DSDT -o DSDT.aml
    # iasl -d DSDT.aml
    # sudo rm DSDT.aml
    # patch < dsdt-error-fw21.patch
    # patch /sys/class/backlight/acpi_video0/brightness Still dims the screen.

    Yes volume works and shows the osd but nothing for FN 5 or FN 6

    dmesg | tail -40 output,,,

    dwade

    December 16, 2008 at 12:10

  68. sorry it cut off this is what I did…

    1. sudo acpidump -b -t DSDT -o DSDT.aml
    2. iasl -d DSDT.aml
    3. sudo rm DSDT.aml
    4. patch < dsdt-error-fw21.
    5. patch < dsdt-ati-fix-fw21.patch
    6. iasl DSDT.dsl
    7. sudo cp DSDT.aml /etc/initramfs-tools/
    8. sudo dpkg-reconfigure linux-image-`uname -r`

    Echo command still works after a reboot.

    dwade

    December 16, 2008 at 12:14

  69. yep, wrong, do this and then reboot and try echo commands again.

    sudo rm /etc/initramfs-tools/DSDT.aml
    sudo dpkg-reconfigure linux-image-`uname -r`
    

    As for sony-laptop, events is fine, I have the same, you should see brightness osd in Ubuntu anyway. But if you are in KDE (Kubuntu), the keys will not work. Anyway I can’t help you anymore with sony-laptop, because it looks ok. Try a clean install of Ubuntu Intrepid.

    For now you can do this:

    sudo pkill "gnome-power-man"
    gnome-power-manager --verbose --no-daemon
    

    then use Fn brightness keys and maybe you can see this in output:

    TI:11:41:22	TH:0x9c0e640	FI:gpm-button.c	FN:gpm_button_filter_x_events,122
     - Key 233 mapped to HAL key brightness-up

    December 16, 2008 at 12:47

  70. I followed your instructions and now
    echo 1 > /sys/class/backlight/acpi_video0/brightness stoped working before I could use it to control the brightness 1-8.

    1. sudo pkill “gnome-power-man”
    2. gnome-power-manager –verbose –no-daemon
    outputs this…

    DO you think a clean install of intrepid will help?

    dwade

    December 17, 2008 at 04:51

  71. Yep, make another partition on your hard drive and install clean Ubuntu there for testings. You will have old installation and new for testings. Then make only 4th step on new. Reboot and try brightness keys. If that not help, I give up.

  73. Hi!
    Nice tutorial! The only thing that’s not working on my sony-vaio is the FN & sound keys. FN+F2 for mute and the multimedia (- and +) buttons. The rest of them I really don’t use.
    The OSD for the sound volume and mute works, but it does nothing. Do you know any solution for this problem?
    Btw, I have a Vaio FW11M.

    Paulo Cabido

    December 17, 2008 at 17:15

    • Paulo Cabido, open volume control (double click on sound icon in tray), then use sound buttons and if you can see one of sliders changing it’s value, possibly it’s front or pcm, there is a solution. If you don’t see this, I can’t help.
      The solution is: go to System->Preferences->Sound, select ALSA everywhere. In default mixer tracks select device HDA Intel (Alsa mixer) and select Master in channels list (there is a tip under that list). Then close and use your sound keys.

    egaistek

    December 18, 2008 at 23:36

  79. Just the fact that uses all the 4gb of RAM. maybe a bit faster on soem applications only. Anyway, if it is not possible to make it work on 64bit I will fall back to 32bit it is not such a big deal.
    Thank you very much anyway.

    Giorgos

    December 19, 2008 at 01:32

    December 21, 2008 at 16:07

  84. I have a FW21J with ubuntu 64 and it has worked great for me. brightness works fine and the fn keys work now too. I have 4Gb ram.
    My only problems were that when I initially downloaded the source code it would not compile because of a function which was not declared anyway (strange), not sure either if the patch worked correctly for me. I deleted that part of the code and then it compiled fine. However, just I did this there was this update from 2.6.27-10 to 2.6.27-11, after updating the fn keys didnt work so I had to download source code againg for -11 and correct it, i did it all manually this time. After booting fn keys were working again.
    So, thanks a lot!!

  88. Worked great for my FW21E with Linux Mint 6! The only thing not described that I had to do was to uncomment the lines with the source rep’s at sources.list. Also, I don’t know what it is supposed to do, but the special key S1 also decreases brightness. I bought this laptop yesterday and already have everything working under linux :)

    stardust

    December 24, 2008 at 05:17

    Try commands from this comment.

    January 8, 2009 at 03:54

  104. I don´t use gnome and my distribution version of gnome-power-manager has no option to change brightness so I can´t tell. I loaded sony-laptop module with debug option as you recommended and output is here:

    Thx for your time.

    VtG

    January 8, 2009 at 05:41

  105. Well, the keys are working. Gnome controls brightness with gnome power manager. sony-laptop patched ok, it just handle key press events, not brightness control. So if you are in KDE or another DE, you should find app to control brightness which can hook on this keys.

    egaistek

  106. OK … I try kpowersafe which look good but it say that my hardware doesn´t support brightness change.

    VtG

    January 8, 2009 at 20:24

  109. Well, I can’t help you with KDE. My patches touching only drivers side and not front-end. If software can not handle hal events, it’s software issues, you can fire a bug on launchpad or bugzilla for kpowersave.
    In this comments I saw someone using KDE too. Maybe he can help.

  111. I have said that the patch worked great…for F5 & F6 function keys ( brightness ) (That was the most important for me…!)…But…but doesn’t work for S1 and AV keys. (VAIO VGN-FW21E)….

    January 9, 2009 at 14:31

    • Charlylerouge, what do you mean by not working? Have you mapped this buttons to do something in keyboard shortcuts preferences? If no, there is nothing to do with this buttons by default.
      If you did it, then make commands from this comment, but for S1 and AV buttons and not brightness.

    I was just elaborating on your method posted earlier. It works great for guessing laptop model! Thanks.

    P.S. I have made a shell script based on your instructions which automates the process, if you are interested in fixing it up, it may be useful to others.

    Thanks again for making this site.

  115. New Note 138

    Hey egaistek,
    Your website has definitely made installing Ubuntu on my FW290 a much easier job.
    I got your tutorial working on kernel 2.6.27-9-generic, no problems. Unfortunately, because of a bug in the kernel (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/286285) I had to enable the intrepid-proposed repo and install kernel 2.6.27-11. The mentioned bug disappeared, but unfortunately I can’t get your tutorial to work anymore. I have re-done all the steps many times, deleting all installed files and installing them again, but no cigar.
    When I press the fn keys, I get the brightness OSD working fine, but does not affect the brightness. Setting the brightness from the panel does nothing. There is nothing in /sys/class/backlight and “cat /proc/acpi/video/VGA/LCD/brightness” throws “” (ie. I can’t echo anything to that file). S1 and AV keys work fine. Any clues?

    Some more info:

    Also, before I was getting, for dmesg | grep -i sony-laptop, an additional comment:
    sony-laptop: Sony: Brightness ignored, must be controlled by ACPI video driver
    But then I found http://www.gossamer-threads.com/lists/linux/kernel/996431 and applied the patch there.
    This only resulted in getting rid of that message, but nothing changed as far as brightness is concerned.

    Pepe Gonzales

    January 11, 2009 at 12:22

    • Pepe Gonzales, there is a bug in 2.6.27-11.23 kernel update from proposed which broken brightness control for many people, bug 311716. If you want to control your brightness, you can use 2.6.27-10 kernel.

    not changing brightness by default and I must do some special key mapping. Could you kick me to right direction how to make this? Sorry for stupid post, but I really don´t know where to start.

  119. works great! I am on a sony vaio fw21z with Ubuntu 8.10 64bit and kernel version 2.6.27-9-generic. I was exactly following your excellent description with only one (hopefully minor) issue. When doing the “make” I get one warning “WARNING: /home/ckny/Downloads/Sony_Vaio_Ubuntu_Patches/kernel_src_and_packages/linux-source-2.6.27/drivers/misc/fujitsu-laptop.o(.text+0xebd): Section mismatch in reference from the function acpi_fujitsu_add() to the variable .init.data:fujitsu_dmi_table
    The function acpi_fujitsu_add() references
    the variable __initdata fujitsu_dmi_table.
    This is often because acpi_fujitsu_add lacks a __initdata
    annotation or the annotation of fujitsu_dmi_table is wrong.”. Do you also get this one?
    I have also added my dmesg output as it differs slightly from yours:
    [ 11.739381] sony-laptop: Sony Notebook Control Driver v0.6.
    [ 11.808158] sony-laptop: detected Sony Vaio FW Series

    and

    [ 0.476846] ACPI: EC: Look up EC in DSDT

    All in all, the brightness keys now work fine and I did not get any kernel panic.

    Nevertheless the S1/AV keys do not work. What do you get if you press them? (In Vista it would invoke a “media center” alike (AV mode) or a dolby surround system (S1)).

    Keep up the great work! Really good manual!

  122. ckny, I could not get it to work on 64 bit.I wonder why, maybe I should use the same Kernel as you. Is the mocrophone working in any of you? Will this fix be included in ant of the nexr ubuntu kernel? I am looking forward to a permanent solution

  124. rodez, have not checked mic yet, but egaistek seems to not have it working. So I guess it’s not possible.

    could you please please add more notes and explain in more details for someone who is a newbie? i tried to do it but i dont know exactly what went wrong.

    when you say Sony-Laptop module to make Fn key work,

    you mean i put my user NAME – Laptop ? l

    like if my startup name is harry-laptop.. i type that?

    or i must just write sony-laptop?

    January 25, 2009 at 14:10

  127. @matt
    Did you apply the patch?
    FTA:
    Then patched with dsdt-error.patch, this patch fix wrong name (”_T_0″) produced by disassembler. Without this patch we can not recompile this table back.

    Pepe Gonzales

    January 25, 2009 at 18:13

  128. @mazin
    I think your comment got cut off.
    But when egaistek says “sony-laptop” he means “sony-laptop”. You shouldn’t have to change any instructions from the post.
    Mazin, please post any error message you might be getting.
    Sometimes when you copy commands from the blog into the console, they might get a hash (#) added, which you have to get rid of. For example,
    # iasl -d DSDT.aml
    change it into
    iasl -d DSDT.aml
    It won’t work with the hash.

    The only problem I ran into with this tutorial is the line:
    make -C /lib/modules/`uname -r`/build/ M=`pwd` modules
    which I had to run with sudo:
    sudo make -C /lib/modules/`uname -r`/build/ M=`pwd` modules

    but my problem is that i DONT get this line:

    16.190130] sony-laptop: detected Sony Vaio FW Series

    so it didnt work, the Fn keys didnt work. i dont know which part i did wrong, im guessing the last part.

    January 26, 2009 at 06:35

    • mazin, as I can see, you have patched DSDT ok. So now you need to remake the fourth step which is for sony-laptop module, this is where you did something wrong.

  134. quick question: I know it’s a little bit off topic, but does anybody have any clue on how getting a 32 bit epson printer driver to work on ubuntu 8.10 desktop 64 bit? Unfortunately, there is only a 32 bit driver provided by an external company for my excellent all in one printer epson PX800FW. That’s one of the last bits that are missing on my Ubuntu 8.10 64 bit setup on my sony vaio FW21Z.

      January 28, 2009 at 01:39

  135. in order to get this to work with the FW3xx series you will need to use a different dsdt-error.patch. Use this instead only if you have trouble recompiling.

    The Error: /sony-vaio-fw-series-brightness-patches/linux-source-2.6.27/drivers/misc/sony-laptop.c:876: error: redefinition of ‘sony_FW_events’
    /sony-vaio-fw-series-brightness-patches/linux-source-2.6.27/drivers/misc/sony-laptop.c:854: error: previous definition of ‘sony_FW_events’ was here

    Anyway i can adjust it using power manager.

  147. Redefinition means there already was these events described. How did you get sources? Maybe this patch merged in Ubuntu already.

    egaistek

    February 13, 2009 at 21:19

  148. My current kernel 2.6.27-11-server. I got the source via apt as it is written in the document. But before done other parts except fourth, i could not change brigthness using power management. Now , i can not use F5 and F6 to change it.

    Probably kernel had modules but id did not work before.

    February 13, 2009 at 21:38

    • For now check if sony-laptop module is loaded (lsmod | grep -i sony). If it’s loaded but Fn keys not work, try to do the 4th step again. Get clean sources then apply the patch.

      egaistek

      February 14, 2009 at 01:51

  149. As you said, Ubuntu has already added this module to the kernel, but it has some bugs. There are some open bug issues about it.

    Fatih Şanda

    February 13, 2009 at 22:02

    • The module was there all the time, I mean maybe they merged this patch. I’ll check then.

  152. yes! I got it working :)

    damn, I’m a java programmer myself, and why was I acting as a noob here?? :) I explicitly declared a boolean variable for all the C scripts where it used the ‘acpi_vendor_backlight_support()’ method, and now everything’s fine!
    Thanks for the great work, egaistek! appreciate!

    ps
    ignore my second post about sony-laptop.c :) it was because I was re-patching on the already patched file :)

    • Начиная с версии ядра 2.6.27-11.12 или выше, в acpi поменяли определение мониторов или панелей на ноутах, поэтому сейчас только VGA, у меня также. Тем не менее, кнопки работают ) Я только не совсем понимаю почему у некоторых возникают проблемы при компиляции с модулем asus-laptop, вроде сорцы одни и теже.

      February 14, 2009 at 01:56

  154. Thanks man, everything is working fine, except the S1, AV-MODE buttons and the internal mic. :)

    as for the compilation problems, I have just replaced the function “acpi_vendor_backlight_support()” to “true” :) assuming that it actually DOES support backlight :) and I’ve done it in all the files that report compilation problems due to the “acpi_vendor_backlight_support()” function.

    а с микрофоном никак? :)

  168. Hi Lynda,

    I am on a Sony Vaio FW21Z with Ubuntu 9.04 64 bit (just upgraded to Jaunty) and am also using an Epson PX800FW. So in case you would like to exchange some info. I am using a trial software at the moment: TurboPrint …
    Feel free to drop me an email: ckny at gmx dot net

    –CKNY alias Christian

    March 28, 2009 at 14:37

  169. Anyone else on Jaunty 64 bit yet?
    Worked pretty smooth. Only (minor) drawback is that some of my applets (using AWN with Mac4Lin) do not work anymore. But it is probably just a matter of time. In addition to that, only 2.6.27-12 works for me. 28.11 leads to a weird screen display that is not usable at all. I had no time to debug so far.
    Other experiences?

  177. hi, thanks for this, everything is working great on my vaio.
    i’ve a dumb question though. not really thinking clearly, i downloaded your patch to a new desktop folder and subsequently have all the files from your tutorial in subfolders of this folder. do i still need it or can i delete it? if i need it, is there a safe way to move it somewhere else – a tutorial perhaps :)?

    cylebrity

    April 14, 2009 at 02:29

  178. cylebrity, you do not need to keep this files =) But if you will update the kernel package, the 4th step must be re-done. So it’s your choice to keep it or not and it’s save to move your folder anywhere you want )

    Which steps did you follow above to get this working?

    for this line –>

    “= 2.6.28-11.36, do not do this step, this patch is included already.”

    –> should I continue on following the rest of the steps after that line??

    I will be upgrading from 8.10 (2.6.27-11) to 9.04 probobly later tonight.

  188. Hey! Just wanted to thank for the patches! I own a FW390 and just did a fresh install of Ubuntu 9.04.
    I had very few problems along the way with the dsdt-error.patch like this:

    DSDT.dsl 3200: If (LEqual (_T_0, 0×04))
    Error 4062 – Object does not exist ^ (_T_0)

    ….

    ASL Input: DSDT.dsl – 8906 lines, 291690 bytes, 3977 keywords
    Compilation complete. 10 Errors, 3 Warnings, 0 Remarks, 1022 Optimizations

    but after a while I figured out all I needed to do was open the DSDT.dsl file with some text editor and switch any “_T_0″ that showed up by “T_0″ to get rid of the errors. I still got 3 warnings after that, but followed the walk-through anyway and after a restart the brightness controls worked perfectly.

    lads@MDK:~/temp/2/sony-vaio-fw-series-brightness-patches$ sudo patch < dsdt-error.patch
    patching file DSDT.dsl
    Hunk #1 FAILED at 8226.
    1 out of 1 hunk FAILED — saving rejects to file DSDT.dsl.rej

    Then, when I try to compile I get the same errors reported by matt here:

    http://vaioubuntu.wordpress.com/2008/12/04/finally-a-brightness-how-to-for-vaio-fw-series/#comment-391

    So I tried the dsdt-error.patch posted by matt:

    http://vaioubuntu.wordpress.com/2008/12/04/finally-a-brightness-how-to-for-vaio-fw-series/#comment-416

    This file seems to be malformed, since it strangely starts with an } character. When applying it I get the following:

    lads@MDK:~/temp/2/sony-vaio-fw-series-brightness-patches$ patch < dsdt-error.patch
    missing header for unified diff at line 3 of patch
    patching file DSDT.dsl
    patch: **** malformed patch at line 4: }

    My DSDT.dsl can be downloaded from here:

    http://www.filefactory.com/file/ag10642/n/DSDT_dsl

    Can you you help in any way? Many thanks.

    • Out of desperation I tried the fix proposed by Andre for the FW390 and substituted the string “_T_0″ in the DSDT.dsl file by “T_0″. Compilation still produces errors, but this way the .aml file is created.

      The remaining steps went out without incident, up to the reboot. Runing the grep commands I get very similar results to those shown in the tutorial. Using the Fn key plus F5 and F6 a little menu shows up with a graphical bar that moves left or right. However, the screen simply keeps at full brightness.

      What went wrong? Can anyone point out how to deal with the remaining errors when compiling the DSDT.dsl file?

      Thank you.

      • Hello again,

        After reading other websites I tried to run acpi_listen to make sure Ubuntu is getting the Fn inputs. Here’s what I got after pressing Fn+F5 and Fn+F6:


        lads@MDK:~$ acpi_listen
        sony/hotkey SNC 00000001 00000010
        sony/hotkey SNC 00000001 0000003b
        sony/hotkey SNC 00000001 00000011
        sony/hotkey SNC 00000001 0000003b

        It seems to me that Ubuntu is getting the correct signals from the keyboard but is either ignoring them or failing to transmit them to the graphics card.

        Any help? Thank you.

      • Ok, Fn keys works as I can see. So you have not patched DSDT right. I’ll take a look right now.

      • Try this DSDT.dsl http://www.filefactory.com/file/ag22aed/n/DSDT_fw31_dsl
        Compile it and follow tutorial from iasl DSDT.dsl line.

      • Horray! It works!

        It reboot and set the brightness to max when the log on screen showed up, but then, when the desktop came up it decreased automatically to what I had set in the previous session.

        Thank you so much egaistek. I think this is might be the final step to leave M$ behind for good :)

  191. Hi, thanks for this tip, but I have a big problem now…

    I have a VGN-FW31E with Ubuntu 9.04. I did your tutorial, patched dsdt-error-fw21.patch, dsdt-error.patch and dsdt-ati-fix-fw21.patch, compile DSDT.dsl and reboot, but now Ubuntu cannot restart any more, it freezes at “Starting up…” !
    When I launch the recovery mode, I see :

    [...]
    [ 0.456420] ACPI: bus type pci registered
    [ 0.456522] PCI: MCFG configuration 0: base e0000000 segment 0 buses 0 – 255
    [ 0.456574] PCI: MCFG area at e0000000 reserved in E820

    [ 0.456672] PCI: Using configuration type 1 for base access]
    [ 0.464494] ACPI : BIOS _OSI(Linux) query ignored

    …and that’s all.
    I start to panic : do I have to install Ubuntu again ?

    • This can’t be just because of DSDT patching, if you did it correct. You can delete DSDT.aml (sudo rm /etc/initramfs-tools/DSDT.aml) file in recovery mode and then do dpkg-reconfigure linux-image-`uname -r` to clear DSDT modification from system.
      If system boots ok, you can try this guide.
      If not, that means that you did something more than just DSDT patching.

  192. Hi,

    Thanks for this patch, it works great on my custom build vaio fw3.

    However I’m having kernel panics do to a buggy iwlagn wireless driver with the factory ubuntu driver.
    Do you have this patch to the latest kernel(2.6.30-rc7) from kernel.org ? I tried to apply it but it failed, the modules has too much changes.

    Thanks

  193. Hi. I have a FW31M and applying the patches as they appear at the beginning return an error, as the (buggy) _T_0 variables seem to appear somewhere else. Anyway, I applied the first and second patches without problems and then I manually corrected the _T_0 variables to be T_0. Compilead and recompiled, and the volume keys are working and nothing else (ethernet, wireless, bluetooth, CD, USB, etc.) seems to be broken, so I assume it is pretty safe.

    Where can / should I send the original and patched up DSDT for other to benefit from this?

    Cheers!

  200. Hi,
    I have a VAIO VGN-FW460J, with Ubuntu 10.10, kernel 2.6.35-22-generic.

    When I use acpi_listen, I got this:

    sony/hotkey SNC 00000001 00000010
    sony/hotkey SNC 00000001 0000003b
    sony/hotkey SNC 00000001 00000011
    sony/hotkey SNC 00000001 0000003b

    Two first lines is for Fn+F5. Two last for Fn+F6.

    Any chances that this tutorial and the other one (http://vaioubuntu.wordpress.com/2009/05/28/quick-brightness-guide-for-jaunty/) doesn’t work just for my model???

    What can I do?

    Thankx
