My problem seems to be related to Bug #1752053 and Bug #1773113. And for me now everything more or less works again by using this workaround from Bug #1752053 posting #123:
---------snip----------------
I found a silly workaround (after trying many many other suggestions / driver re-installs), now using nvidia-driver-396 or nvidia-driver-390; create (if not exists) a file /etc/rc.local, with this content:
#!/bin/bash
sleep 1
exit 0
And make it executable: chmod 755 /etc/rc.local
