To recover from the black screen : - switch to a VT (ctrl+shift+F3) - execute "sleep 5; xrandr -d :0 --output LVDS1 --auto" with the proper output name - switch back to the Xorg VT (ctrl+shift+F2 in my case) Without the sleep, xrandr will fail since it cannot change the config when the current VT isn't Xorg. Git commit d3c0b50e3b23c4f4839f15dda3af4361939ae484 by Daniel Vrátil. Committed on 13/02/2016 at 14:25. Pushed by dvratil into branch 'Plasma/5.5'. XRandR: handle changeOutput() without CRTC better It is possible that XRandROutput counterpart to KScreen::Output does not have a CRTC set while the KScreen::Output reports itself as enabled. This leads to changeOutput() hitting an assert, because we assumed that such case can never happen. Now we know it can, so instead when changeOutput() is called for an output without CRTC, we fallback to calling enableOutput().

Created attachment 91404 [details] Full backtrace of libkscreen crash I have 6 different config files in ~/.local/share/kscreen - one of them (44a2d0cb08898ad49134cc7b37130158) makes plasmashell crash on startup. Running KF5/Plasma 5 from git - all up-to-date + Qt 5.4.1. Full backtrace is attached. All kscreen config files will be attached.
