Brightness control doesn't work on Solus Budgie
Open, Needs TriagePublic


After fixing the suspend issue I had in T7517 2 new backlight devices appeared in /sys/class/backlight making 3 folders in total: intel_backlight, acpi_video0 and acpi_video1.

When I use the brightness hotkeys on my keyboard the backlight window appears the bar increases/decreases depending on the button pressed but the screen doesn't brighten/dimm accordingly. But when I use echo {value} > /sys/class/backlight/intel_backlight/brightness the screen dimms/brighten as it's supposed to so I think I just need to tell Budgie to access this brightness controller instead of the other ones, how can I do that ?

EDIT: I already tried to mask systemd-backlight@backlight:acpi_video0 and systemd-backlight@backlight:acpi_video1, it doesn't solve the problem

Update: when I plug in the laptop the brightness goes to its max, when I unplug it brightness goes down to its minimum.

I don't actually know what is responsible for this so I don't know if that helps
