Hi, |
22 |
fisrt see if proc and your kernel has it right, do: |
23 |
cat /proc/acpi/video/GFX0/DD02/brightness |
24 |
|
25 |
should give something like |
26 |
|
27 |
levels: 13 25 38 50 63 75 88 100 |
28 |
current: 13 |
29 |
|
30 |
if that works, check permissions on the file and try to echo a level |
31 |
number to it.. |
32 |
|
33 |
echo 13 > /proc/acpi/video/GFX0/DD02/brightness |
34 |
|
35 |
it it changes then its down to the app, check the use flags of the app, |
36 |
and see whats missing. |
37 |
|
38 |
good luck |
