Application: plasmashell (5.3.1) Qt Version: 5.4.2 Operating System: Linux 4.1.0-0.rc7.git0.1.fc23.x86_64 x86_64 Distribution: "Fedora release 23 (Rawhide)" -- Information about the crash: - What I was doing when the application crashed: Booting from the login screen. Note that this IS a :Rawhide" system, using kernel 4.1, rc7, and that the GNOME session also will not start. (MATE , however, does start). This is the first time (since rc3) that the abort reporting system has worked, so I thought a traceback might be useful. The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

>#11 0x00007f73e67a54bb in QOpenGLContext::create() () at /lib64/libQt5Gui.so. An error here normally means that there's some setup issue where your computer where we can't start openGL. Can you double check you have your graphic drivers are set up correctly. Most distributions ship s a test app called glxgears that shows if graphic drivers are working correctly. Can you confirm if this is working? Thanks.
No video driver problem that I can see. (I use the standard open source ATI Radeon driver.) I have several programs in my ".config/autostart" that run (as windows) after the plasma shell crashes. This post is coming from "google-chrome-stable" started from a terminal window started from one of the autostart programs. I just used it open a video link tab, and it played the video with no problem (expect no sound, but I have the sound turned off because my wife's asleep about a meter away from my system, so didn't want to test that right now. :-) ) Note, however, that those windows are, as would be expected, "undecorated."
Oops! I just checked glxgears, and GLX was not installed. And a grep of Xorg.0.log confirmed that error. And also AIGLX, but that's probably from the GLX failure. Well, this is a Fedora "rawhide" system, so we can't expect everything to work. :-(
Thanks for commenting back, let us know if you manage to fix it.
