I have Xubuntu 12.04 with latest updates on Toshiba Satellite A210-15K laptop

...and I can't adjust LCD brightness (. I tried to use fnfx tool:
semen@bloknot:~$ fnfx-client
FnFX Client v0.3 (c) 2003, 2004 Timo Hoenig <[email protected]>
fatal error: Could not open "/home/semen/.fnfxrc". Please make sure that the default config is accessible.
...and xbacklight:
semen@bloknot:~$ xbacklight
No outputs have backlight property
...and I tried to add acpi_osi=Linux and acpi_backlight=vendor parameters in GRUB config, but nothing happens.
I soppose .fnfxrc file must be available after installation or first fnfx demon lauch. Isn't it?
semen@bloknot:~$ cat /sys/class/backlight/toshiba/brightness
-5
semen@bloknot:~$ cat /sys/class/backlight/toshiba/max_brightness
7
semen@bloknot:~$ echo 6 | sudo tee /sys/class/backlight/toshiba/brightness
[sudo] password for semen:

...
...but brightness is the same.
Help, please.
P.S. Execuse me for my poor English.
UPD. I have spent 2 days to solve this boring problem, but I can't. So. If I wish linux work correctly, I have to choose another distro.
radeon
driver? Or did you install the proprietary driver? You can check by typinglspci -v
in the terminal and looking for the section heading with VGA in it. Kernel driver in use will stateradeon
if you are using the default.fglrx
proprietary driver, which supports your graphics card, and see if brightness will work then. I believe you can justsudo apt-get install fglrx
. Many people use it and have no problems... but switching graphics drivers can cause major issues. Please don't do this unless you really are bugged by the brightness issue.
