Ubuntu – I can’t modify the screen brightness on Xubuntu 13.10

brightnessnvidiavaioxubuntu

I got this problem with brightness on my fresh xubuntu 13.10 install..
It ain't inc/decrease the screen brightness when pressing Fn+F5/F6 !!

I've tried some solutions like setting these values in the /etc/default/grub file and sudo updating grub (this worked for me on my previous xubuntu 13.04 install)

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor"
GRUB_CMDLINE_LINUX="acpi_osi=Linux acpi_backlight=vendor"

But still not working though :/

I have got a Sony VAIO VPCEJ3B1E running xubuntu 13.10 x64bit
and an NVidia GeForce 410M and using the propritory drivers 319

Thanks in advance!

I am having the same problem with Ubuntu 13.10 install. My brightness shortcut keys (Fn + F5/F6) worked in 12.10 as well as 13.04.

I am using Sony Vaio SVE15113ENB with VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09). Any help is appreciated.

I have tried:

Installing Additional Drivers from Software Centre
Finding /etc/X11/Xorg.con file but it does not exist for me.
Modifying grub file and sudo updating grub and then reboot.

Ubuntu – Screen brightness control not working on Lenovo T530

I had a similar problem on my thinkpad W530. I finally found a solution here:

These days X automatically configures itself, so you can't just edit the xorg.conf file, you instead need to add a section to a file in /usr/share/X11/xorg.conf.d/ and X will include that section in the configuration that it automatically generates.

So to get the screen brightness keys working with your Nvidia graphics card, create a file in the xorg.conf.d directory, e.g:

sudo gedit /usr/share/X11/xorg.conf.d/10-nvidia-brightness.conf

Paste the following into the file:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "Quadro K1000M"
    Option         "RegistryDwords" "EnableBrightnessControl=1"

Ubuntu – Ubuntu 14.04 LTS: FN-Brightness Key Stopped Working

Please try:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"

It works at least for me on my acer asus 1005P, contrary to what it's written here. (maybe the kernels are different).
