Crashes require a backtrace.
Comment 2 Texstar 2020-03-03 21:57:36 UTC 
I can't provide a backtrace because it works with my nouveau and Nvidia 440.64 drivers. I backed systemsettings down to 5.17.5 but it is still crashing for some i915 video cards so the problem exists somewhere else. I'll keep poking around then. Thanks!
Comment 3 Texstar 2020-03-05 17:47:00 UTC 
Found that systemsettings crash on some Intel systems that use the Intel Video driver! If the user switches to modesetting then systemsettings work as intended. It is not in systemsetting either as I backed the package down to 5.17.5 and it still crashed. I cannot provide a backtrace so I guess if you can't duplicate it then it will stay as is... broken.
