[Moderator edit: Changed title to try to attract relevant answers. Original title was simply xbacklight. -Hu]
xbacklight does not work.
DE - i3
It is installed correctly.
| Code: | reik@reik-msi ~ $ emerge --search xbacklight
[ Results for search key : xbacklight ]

Latest version available: 1.2.2
Latest version installed: 1.2.2

The commands are executed properly
| Code: | reik@reik-msi ~ $ xbacklight -dec 50
reik@reik-msi ~ $ |
But the brightness does not increase or decrease.

Which video card?
What is in " /sys/class/backlight"?
OR what does "find /sys/ -type f -iname '*brightness*'" return?
Do shortcut keys for brightness work? |
