It's a bug in Qt5 - expected to be fixed in 5.5 The problem is that your X11 server has no RandR extension (resp. has it disabled) but Qt relies on it. Notice that the lack of the RandR extension is extremely uncommon and might point a problem with your installation/setup. *** This bug has been marked as a duplicate of bug 343844 *** |
Application: kwin_x11 (5.3.0) Qt Version: 5.4.1 Operating System: Linux 4.0.4-301.fc22.x86_64 x86_64 Distribution: "Fedora release 22 (Twenty Two)" -- Information about the crash: - Unusual behavior I noticed: 1). Login as usual and proceed to coloured screen progress bar gets less than a quarter of the way and login bombs out. 2). Get message saying kwin is unstable - kwin_x11 3). Sometimes progress bar gets nearly halfway then kded5 bombs out instead foe which I have a backtrace but cannot report this bug as system tells me I cannot! The crash can be reproduced every time. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
