1) Press Ctrl + Alt + F1 and login with username and password 2) sudo apt install gnome-session-flashback 3) sudo service lightdm restart 4) Select Gnome (metacity) session and login. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1639180 Title: no login possible after update to nvidia 304.132 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-304/+bug/1639180/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
