|
|
Hello,
I can't change my screen brightness. I'm using gnome 2, if I click on brightness applet on my gnome-panel, it's show me an error:
"https://www.dropbox.com/s/9f7ak765s16c5zx/Captura_de_tela.png"
The translation of my error is, "Cannot get laptop panel brightness"
I can't use the command "xbacklight" if I try it show me:
Code: |
# xbacklight
No outputs have backlight property
|
and my backlight's directory is empty
Code: |
# ls -a /sys/class/backlight/
. ..
|
So how cai I fix it?
Thanks.

Do you have ACPI_VIDEO enabled in your kernel? (and loaded if built as module) |
