Status update from me. The hang with nvidia-drm.fbdev=1 is caused by gpu-manager.service which is: WantedBy=display-manager.service Before=display-manager.service
In my previous testing delaying gdm.service with udev-settle really just caused to delay gpu-manager.service which fixes this issue. I'm now thinking that gpu-manager.service is also the cause of bug 2063143. It also explains why I don't hit any of these bugs in Fedora, as gpu- manager.service is only shipped in ubuntu: https://github.com/canonical/ubuntu-drivers- common/blob/master/share/hybrid/gpu-manager.c -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060268 Title: Phantom "Unknown Display" shown in Settings after installing the Nvidia driver To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/2060268/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
