Application: plasmashell (5.5.5) Qt Version: 5.5.1 Operating System: Linux 4.4.0-47-generic x86_64 Distribution: Ubuntu 16.04.1 LTS -- Information about the crash: - What I was doing when the application crashed: Either system restart or startx from terminal - Unusual behavior I noticed: On system restart, loads to non-responsive blank black screen with only funtioning mouse pointer. Ctrl-alt-F(1-6) starts terminal, and startx results in three separate Plasma crash reports. This is the output of the first report. The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Aborted Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

It's related to upgrade from nvidia-304=304.131-0ubuntu3 to nvidia-304=304.132-0ubuntu0.16.04.2 (or, maybe, other versions in your case). You can (temporarily) downgrade your ndivia package as workaround. Also, please support this Ubuntu bug-report: https://bugs.launchpad.net/ubuntu/+source/plasma-workspace/+bug/1640451 -- to make it confirmed.
