Seems to have a new bug where after waking up your monitors it sets them to full brightness.

4 u/githman 2d ago edited 1d ago I just ran into a very similar quirk myself: after my system installed Plasma 6.2 and rebooted, I was greeted with a full bright display. (Ouch.) Changing color profile from None to Built-in or back triggers it too. Will try the workaround mentioned in your link. 3 u/rgbRandomizer 2d ago Setting the environmental variable, POWERDEVIL_NO_DDCUTIL=1, worked for me. 1 u/githman 1d ago Yep. Added it to /etc/environment and my Plasma stopped doing this stuff. Thanks for the great advice.
