Please check that Wayland has NOT been disabled in /etc/gdm3/custom.conf And if the login screen issue happens again then from Ctrl+Alt+F4 please run:
journalctl -b0 > failednow.txt and attach the resulting text file here. BTW, the very fact that you can see an X cross on a black screen means you're using X. Please disable auto-login and try selecting 'Ubuntu on Wayland' on the login screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2076106 Title: Xorg freeze (black screen, only the X mouse cursor moving) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2076106/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
