10.10 with applet

leave a comment »

Who have problems with brightness fn keys in 10.10 ubuntu, please check if gnome brightness applet works for you (right click on gnome panel, add to panel, search brightness).

I see people still having problems with fw4x,fw5x models. I’m not much help here, because for me it just works now.

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:

# by Anton Veretenenko
# version: 0.2


if [ ! $# -eq 0 ]
echo “Use: sudo ./dsdt-patch”

if [ ! “$isroot” == “root” ]
echo “Error: Make sure you run this script with sudo”

echo “Creating temp directory”
mkdir “/tmp/$patch_temp_dir”

if [ ! -x /usr/sbin/dmidecode ]
# if dmidecode isn’t found, let’s install it too
echo “Installing dmidecode”
apt-get install dmidecode
echo “dmidecode found”

isfw1=`dmidecode –type system | grep -i -c -P -e “Product Name: VGN-FW(1).*”`
isfw2=`dmidecode –type system | grep -i -c -P -e “Product Name: VGN-FW(2).*”`
isfw3=`dmidecode –type system | grep -i -c -P -e “Product Name: VGN-FW(3).*”`
isfw4=`dmidecode –type system | grep -i -c -P -e “Product Name: VGN-FW(4).*”`

elif [ “$isfw4” == “1” ]

rm -rfd “/tmp/$patch_temp_dir/”

if [ ! -r “$patch_file” ]
echo “Error: Could not read $patch_file file”
rm -rfd “/tmp/$patch_temp_dir/”
echo “Selected $patch_file patch for you”

cp “$patch_file” “/tmp/$patch_temp_dir/”

echo “acpidump found”

echo “patch command found”

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 =)
