Since KDE can’t figure out that a) something is fullscreen and b) my gamepad is used, i need to keep my screen from turning black by switching to a “gaming” activity that has screen dimming & blackening turned off. The necessary settings are missing in plasma 5 / KF5. Reproducible: Always
I might add that I don't find it very intuitive to have those activity-related settings in tabs - once they re-appear in 5.x just my 2 cents
Activity-related settings will return in 5.3 as per [1] [1] http://quickgit.kde.org/?p=powerdevil.git&a=commit&h=0e27382a423509d21f706f65831a7d461e6571c0
