Hi, fisrt see if proc and your kernel has it right, do: cat /proc/acpi/video/GFX0/DD02/brightness should give something like levels: 13 25 38 50 63 75 88 100 current: 13 if that works, check permissions on the file and try to echo a level number to it.. echo 13 > /proc/acpi/video/GFX0/DD02/brightness it it changes then its down to the app, check the use flags of the app, and see whats missing. good luck -- Regards, Roundyz
