> During boot, when does exactly "/bin/rm /dev/dri/card0" run? Would that run in the initrd environment? I ask because of comment #37, which said they lost the display during the luks password prompt. Although I believe that's because of the workaround they were using then, which was to disable simpledrm via the kernel command line.
It runs when nvidia-drm is added: ACTION=="add", SUBSYSTEM=="module", KERNEL=="nvidia_drm" but I don't remember if we still allow that to happen in initrd or afterwards. It depends on the current state of the Nvidia drivers' packaging. If nvidia-drm is loaded during initrd then yes I imagine that might create a problem... although usually devices already in use still exist in the kernel after you delete the /dev entry. If Plymouth was already rendering on card0 then it shouldn't suddenly turn the screen black just because there's no longer a device node on disk. I think the bug you describe was more likely due to the workaround and didn't blank a previously working screen, but rather made it blank from the beginning. TL;DR - probably no bug but we have a regression test anyway. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
