Followup-For: Bug #837895
I can confirm this bug on another platform. I also updated packages
before rebooting today.
Initially a mouse symbol appears in the middle of the screen, then
after a few seconds is displayed in the left upper corner.
When - despite the black screen - typing in credentials (username tab
password enter), first a cursor ('_') appears in the left upper
corner of the screen and after a few seconds a mouse symbol again.
Thus it seems the greeter does react somehow.
When installing lightdm-kde-greeter as a replacement, I can login
to Mate (and some things there don't work well).
If I can help testing something, please let me know.
