http://bugzilla.opensuse.org/show_bug.cgi?id=954228 Bug ID: 954228 Summary: kscreen config broken after external monitor unplugged Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.1 Hardware: x86-64 OS: openSUSE 42.1 Status: NEW Severity: Normal Priority: P5 - None Component: KDE Workspace (Plasma) Assignee: kde-maintainers@suse.de Reporter: mludvig@logix.net.nz QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:41.0) Gecko/20100101 Firefox/41.0 Build Identifier: I've got a laptop with external monitor. Configured with the KDE Configure Desktop app to be "above" the laptop screen. When leaving from work I unplugged the monitor, closed the laptop lid and later at home when it resumed only got a black screen. Restarting didn't help - I got the startup splash and brief glimpse of X.org startup screen and then it turned black again. After much testing I figured that the file ~/.local/share/kscreen/8f27e66f2df16668f11cfb00c42a0786 contained section: "pos": { "x": 0, "y": 1080 }, Which turned out to be the problem. Apparently offset below the now-unplugged external monitor. Once I changed 1080 to 0 and restarted laptop it came up all right. IMO kscreen should be more intelligent and figure out that the recorded screen configuration doesn't make sense and readjust the coordinates.
