Ubuntu 9.10 Karmic Koala beta

with 47 comments

I just want to inform you, if you have not tried it yet. Brightness control works out of the box. S1 key works, AV key does not. Headphones jack detection works. Built-in microphone does not. Web camera works in Skype.

Dmesg output when using AV key:

sony-laptop: Unknown event: 0x100 0xa1
sony-laptop: Unknown event: 0x100 0x21

I guess sony-laptop module is without our patch or just a new one. I’ll check sources when I have time.

Stay tuned.

Quick brightness guide for Jaunty

with 62 comments

This little guide is faster an easier version of previous brightness how to. Since Jaunty already have sony-laptop patch included, we need to patch our DSDT bios table only and override default one with patched, while kernel is loading. I saw many people have problems with DSDT compiling, so I removed dsdt-error.patch patches from pack, and changed it with another line in terminal.

I have made a script which will make all what needed, you just need to select right patch for your model. Download new patches pack. Unpack it, then pop up your terminal and go into that directory, where you’ve unpacked it. There is 3 patches included dsdt-ati-fix-fw1x.patch, dsdt-ati-fix-fw2x.patch, dsdt-ati-fix-fw3x.patch. If you have FW3x(x) model, then use dsdt-ati-fix-fw3x.patch and so on for FW1x(x)/FW2x(x). Ok, you’ve made your choice, now just type this in terminal:

Ok, I have changed script and make him choose the right patch for you, just type this in terminal then:

sudo ./dsdt-patch

That’s all 🙂

Here is a source code of that script, for those who interested:

echo “Use: sudo ./dsdt-patch”

New sony-laptop brightness control

with 44 comments

I’m thinking on updating this module with another brightness control which does not require DSDT patching.

It’s based on changing hardware registers on Ati card and work with radeonhd and fglrx drivers only. Worth it or not, what do you think guys?

It’s possibly would not work with power manager, only with fn keys and maybe without onscreen osd 🙂

If someone have laptop with fullhd screen, I would like to test this method with you, because you have another Ati card.

S1 and AV Mode keys

with 6 comments

I have updated sony-laptop module patch with enabled S1 and AV Mode media keys. You can map this keys in System->Preferences->Keyboard Shortcuts.

Download new sony-laptop patch (it’s included with patches for the post about brightness). Then do the 4th step in brightness how to.

Finally a brightness How To for Vaio FW Series

with 230 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 <strong>dsdt-error.patch</strong>, this patch fix wrong name ("_T_0") produced by disassembler. Without this patch we can not recompile this table back. Then we patch with <strong>dsdt-ati-fix.patch</strong>, this is the actual fix made by <strong>Zhang Rui</strong> 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 <strong>sony-laptop</strong> module to make our Fn keys for brightness work correctly:

<span style="color:#ff0000;">UPD</span>: If you have Jaunty kernel version &gt;= 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 <strong>sony-laptop</strong> 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 =)
