Hm, strange. I use the standard intel graphics drivers that come with ubuntu. I did not install anything else.
Maybe it's a problem of the users I have created? I created 3 other users (see below with their respective UID). ubuntu:1000 user1:1001 user2:999 user3:1002 Only ubuntu and user3 have passwords set. user1 and user2 do not appear in the login screen (I removed both from login screen). Anyways - could that be the problem? But if so - why did this does not make problems with the former gdm3-version? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1691357 Title: User switch not possible, login screen black To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1691357/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
