After completely removing the nvidia drivers, rebooting, and reinstalling the nvidia drivers, even the old kernel fails to boot. This appears to be an nvidia driver issue that shows up because of the gdm3 setup where it runs two different Xorg instances. Under lightdm+gnome the displays light up normally.
re-removing the kernel versions as with the new nvidia drivers on the old kernel we're still broken. ** Summary changed: - Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 using kernel 4.15.0-38, but 4.15.0-36-generic works + Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799994 Title: Xorg loads, no display on nvidia 390.77-0ubuntu0.18.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1799994/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
