How can i make Brightness Control work?
- by Semen
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.
