I also have the same problem on Ubuntu 18.04.2. The login screen starts normally, but right after typing my password and pressing enter the screen is black.
The problem started after an NVIDIA driver update with "apt upgrade". I was using the nvidia driver form the CUDA Repository. I tried removing and reinstalling nvidia-390 from Ubuntu repos, 410 and 418 from cuda repo and 418 runfile installer from NVIDIA Homepage. The bug is the same for all driver versions. When I uninstall nvidia driver und use nouveau, everything is fine. Also when using the nvidia driver i can login with SSH and `systemctl stop gdm.service` + `systemctl start gdm.service`, then login works fine. Finally switching to lightdm also works now as workaround. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763774 Title: nvidia-driver-390 GDM black screen / hang after login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1763774/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
