Hello, I'm a google code-in student with a task of bugtriaging. I would like you to try to reproduce the bug at least one more time to see if it's possible to reproduce. Thanks, William And I was not able to reproduce the bug running Fedora 20 with KDE4. A lot of multiscreen was fixed in Plasma 5.1.2 |
Application: plasmashell () Qt Version: 5.3.2 Operating System: Linux 3.17.6-300.fc21.x86_64 x86_64 Distribution (Platform): Fedora RPMs -- Information about the crash: - What I was doing when the application crashed: Over the weekend, I installed plasma and had numerous issues. I'm working through them, though. I've now got to configure my external monitors when I'm using my docking station. I enabled the two monitors in "Display Configuration - System Settings" and when I hit apply, it tried to get them started and that's when it crashed. I haven't tried to recreate the issue. - Unusual behavior I noticed: Nothing too crazy. - Custom settings of the application: This happened when I was trying to configure my external monitors. -- Backtrace: Application: plasmashell (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
