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

semen@bloknot:~$ uname -a
Linux bloknot 3.2.0-24-generic #37-Ubuntu SMP Wed Apr 25 08:43:22 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

...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: 
6
...

...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.
