Created attachment 112872 [details] The error report created from the crash My systemsettings application crashes when I attempt to access the display and monitor configuration while in single screen mode. The whole systemsettings application freezes for a short moment before ultimately crashing and closing. This behavior is reproducible at least for KWin under X
I ran into the same problem after upgrading today. I could "fix" the problem by downgrading libkf5screen7 via: apt install libkf5screen7=4:5.12.5-0neon+16.04+xenial+build60
Nice to know, but that seems to be a problem in the display libraries then, which could be probably fixed by providing an updated version of libkf5screen7
Update should resolve it.
