Subject description: tried almost everything...
 

Hey, before asking i searched on the forum. The problem is none of the answers could help me. Xgamma controls gamma... i need to adjust brightness. I tried with xbacklight but it says there is no backlight output compatibility. Also in my /proc/acpi folder i have no video folder. Anyone? The graphics is an intel gma HD card..

Which model are you using?

The linlap.com suggest this fix for the 8540

The fn+f9,f10 keys (screen brightness/backlight) can be enabled by

editing /usr/share/hal/fdi/information/10freedesktop/10-laptop-panel-hardware.fdi at line 27 so that it reads:

match key=”/org/freedesktop/Hal/devices/computer:system.hardware.product” contains_outof=“8540p;4410s;4415s;4416s;Compaq 5×5”

then reboot.

see...
