Application: plasmashell (5.8.6) Qt Version: 5.6.1 Frameworks Version: 5.26.0 Operating System: Linux 4.4.57-18.3-default x86_64 Distribution: "openSUSE Leap 42.2" -- Information about the crash: - What I was doing when the application crashed: booted after creation of a new activity to resolve the screensaver behaviour using SuSE Leap 42.2 - Unusual behavior I noticed: when closing the lid of the laptop screen the ext Monitor was disconnected - no signal worked fine with just the default activity, occoured right after creation of a new activity and reboot After reboot the login screen was added by a chooser for different window managers This chooser appeared twice, just the upper one worked. Very strange entries in this list, Plasma 5, Plasma Workplace, Plasma Default and two others. Which one to choose ? With just the default activity it worked fine. I just tried to get rid of the login screen every few minutes. Really annoying when watching a video. - Custom settings of the application: see above. The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

Additional comment from stephan.dietzel@t-online.de Apr. 02nd, 2017 Laptop HP 2760p, SuSE Leap 42.2, kernel 4.4.57-18.3.1 ( upgrade Apr 01st, 2017 ) This malfunction started after kernel upgrade ! Not easy noticable because the updates are running automatically and I did not reboot during the day. So changes took place when rebooting in the evening. Before re-boot I created a new activity to prevent the screensaver to start when attached to external monitor at watching video. ( extended energy settings ) So here 3 things go with each other : kernel update, plasmashell update, new activity with extended energy settings. plasmashell 5.8.6 creates a double picture on login screen. Can be seen because the lower part of the shadow of the SuSE Bulb is shown twice on the lower edge of the screen. It seems that it started up with the correct screen resolution of 1280 x 800 and then started a second instance with a resolution of 1280 x 720. After logging in, at first a resolution of 1280 x 720 is shown that a minute later is drawn then as 1280 x 720. When trying to shut down, a double picture is shown, both resolutions at the same time, as a milky overlay picture. Double monitor feature does not work. Startup and shutdown time extremely long. Process listing just shows 1 instance of plasmashell. Downgraded with Yast to 5.8.3 which seems to work well. Best Regards Stephan
