SUMMARY
I've been using KDE Plasma in Artix (dinit) on my AMD laptop (igpu radeon 880m)
with an external hdmi display always plugged in and the lid closed. Since the
last plasma update 6.6 my hdmi display goes on and off on its own regardless if
I keep the lid open or closed. My power management settings are set to stay
always awake and to never turn the display off when an external monitor is
connected.
No issue whatsoever if I unplug the external display from the hdmi port and use
the "internal" one only. Also before plasma 6.6.0 it worked flawless as
expected. Please see attached video.
Thanks a lot
STEPS TO REPRODUCE
1. connect an hdmi display to a laptop
OBSERVED RESULT
External display connected via hdmi goes on and off on its own, regardless if
the notebook lid is closed or open
EXPECTED RESULT
Display stays on, regardless if the notebook lid is closed or open
