[Bug 1492778] Re: kde crashes when powering on/off monitor

Sun Dec 13 10:10:45 UTC 2015

Crash of sddm/kde/plasma/X also occurs when switching off the (only) UHD monitor connected via 
- displayport under kubuntu 15.10, 
- geforce 850 graphics card and nvidia-352.63 driver.
Sometimes virtual console (Strg+Alt+F1) is still accessible and X can be restarted via init 3; init 5, often not even the virtual console is visible and the computer needs a reboot.
Adding workaround of squarooticus in xorg.conf 
Section "Screen"
    Identifier "Screen0"
    DefaultDepth 24
    Option "MetaModes" "DFP-3: 3840x2160 +0+0, DFP-4: 3840x2160 +3840+0"
    Option "ConnectedMonitor" "DFP-4, DFP-6"
EndSection
(where DFP-3 is the only existing monitor) did not help here.
This makes the distro unusable (and I switched from OpenSuSE to kubuntu to try a better distro :-(   )
