Black screen with cursor after upgrading

[Guest]

Hi,
After upgrading from 15.04 I get a black screen with a cursor (x). After running dmesg in a terminal I can see the following message:
"sddm-greeter[1602]: segfault at 28 ip .........error 4 in libGL.so.1.2.21..."
Thanks.

I have the same problem, black screen with cursor even after succesfull login sound. After Alt+F2 I run plasmashell, because I thought that plasma was not running, without success. Than I tried Shft+ESC and I saw two plasmashell runnig, original and mine. How can plasma be running with black screen?

My problem appears only from time to time and can be temporarily solved by restart.

Were you using the nvidia binary blob before the upgrade? If so, you should try to reinstall them.
