Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.21-14-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
I allowed an online update to occur today.  I noticed that there was an Nvidia update but did not catch the detail.  After install the system crashed with a message to the effect that the screen locker was no longer functioning.  I ended the sessions and restarted the system.  I am now experiencing a blank screen.  Past occurrances were the result of an incorrect Nvidia driver as well as an incorrect setting in the etc/sys/config desktop display.  Mine was set to "sddm" I changed to KDM resulting in the XCFE desktop working minimally.  Minimally in that I can get this far.

The crash can be reproduced every time.
