Hello,
I can't change the brightness under Plasma anymore since my last update of three month worth of updates. It is still working perfectly on GDM (never managed to make SDDM work).
Maybe it is related to the fact that I have a phantom output detected (LVDS1) in addition to the display of my laptop (LVDS-1) and that my system tries to change the brightnes value of the phantom display.
Could not find any more information online for both of this problems.
Thank you for your help.
Johan

I was able to collect more information:
I have two backlight entries in /sys/class/backlight.
-gmux_backlight
-intel_backlight
The keyboard key and the selector in Plasma are modifying the wrong value: intel_backlight.
When manually modifying gmux_backlight I can dim my screen. How can I force (PowerDevil) the change the right value?
Thanks for your help
