What we know about this bug is that gdm3, nvidia and modeset=1 is broken under configurations which are not broken when sddm and lightdm are used.
we know that gdm3 sessions with external monitors work with root permissions. we know that gdm3 compiled with wayland also works (according to the gentoo user generix). And neither gnome developers nor nvidia acknowledge a bug. If you make a venn diagram of all of this, gdm3 is the intersection of every observation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1716857 Title: nvidia-drm.modeset=1 results in no monitors detected by Xorg To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1716857/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
