Application: kded4 (4.12.4) KDE Platform Version: 4.12.4 Qt Version: 4.8.5 Operating System: Linux 3.13.10-200.fc20.x86_64 x86_64 Distribution: "Fedora release 20 (Heisenbug)" -- Information about the crash: - What I was doing when the application crashed: xrandr --setprovideroutputsource Intel NVIDIA-0 xrandr --output DP-0 --auto --panning 3840x1080+0+0/1920x1080+0+0 --output VGA-0 --panning 3840x1080+1920+0/1920x1080+1920+0 --output LVDS1 --auto --right-of VGA-0 (enables Intel card piping to laptop screen, spans desktop to all 3 monitors) - Unusual behavior I noticed: KDE doesn't grok the left monitor's existence. The background for that screen is black, there's no process bar along the bottom, KDE spans the desktop across the right monitor (on NVidia) and the laptop display (Intel) $ xrandr -q Screen 0:
