Thanks. Comment #14 indeed shows you ran into a lot of trouble on 2018-06-15 and tried a lot of things to fix the nvidia drivers. The only thing is that the nvidia drivers have never changed at all since their release in April:
https://launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390 So Nvidia updates can't be the issue. Something that did happen just before the problem began was a kernel upgrade: https://launchpad.net/ubuntu/+source/linux/4.15.0-23.25 So that will have necessitated a rebuild of the nvidia kernel driver, which might have failed and would explain the issue. So... 1. Can you find any log or text files under /var/log/dkms ? 2. Can you please run 'lspci -k' on the machine and send us the output? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1777378 Title: GDM no longer presents GUI login Ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1777378/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
