I had a variant of this problem (on Lenovo P51, M2200 Nvidia): After upgrade from 17.10, where everything worked fine, to 18.04 the laptop still booted normally (I DID get login and desktop) but when I suspended or locked the screen I also got black screen and curser in upper left corner.
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 ---------snip---------------- Maybe this helps some people. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1773113 Title: nvidia-390 does not show GUI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1773113/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
