But we need more information to debug the issue. Are you able to provide a journal file? Boot the machine, reproduce the issue, switch virtual console, run: journalctl -b0 > journal.txt and attach the file here. Then, if you suspect this is an issue with the display manager, you could try starting a desktop session from the terminal with: XDG_SESSION_TYPE=wayland dbus-run-session gnome-session -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2090805 Title: gdm blank screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/2090805/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
