Hi, I installed xorg-x11. (because i wanted x11-wm/i3). xorg-x11 depends on xbacklight.
My problem was that xbacklight didn't work because of an error:
$ xbacklight -get
No outputs have backlight property
So, searching on the internet, I found this package: sys-power/acpilight, which works perfectly.
From https://github.com/wavexx/acpilight :
So, in the end, all I did was:
$ emerge --unmerge xbacklight
$ emerge acpilight
Now, I can perfectly use my i3 WM, change brightness... without any issues.
The only problem is that i can't update my system anymore. Since xorg-x11 (which is still installed) depends on xbacklight, when I try to update the system I got:
$ sudo emerge -auvDN @world
These are the packages that would be merged, in order:
Calculating dependencies... done!

Is there a way to keep xorg-x11 and acpilight, maybe masking xbacklight ? What is the right way to do it?
