My problem began when I tried to use 2nd monitor (with vga cable). Every now and then all plasmoids, panels and background would disappear from my primary monitor (hdmi) and they would appear on my 2nd monitor. Doing "killall plasmashell && kstart plasmashell" fixes this. It have now unplugged 2nd monitor but same behaviour continues with primary monitor. Happens especially after returning from suspend. I have a laptop which own monitor is disabled. I tried removing ~/.local/share/kscreen/ but that didn't help. What could I do? I'm using openSUSE TW, Plasma 5.5.5.

Code: Select all

>xrandr --listmonitors
Monitors: 1
 0: +*HDMI1 1920/531x1080/299+0+0  HDMI1

~/.Xsession-errors -output when suspending and this happens:

Code: Select all
