Public bug reported: This may relate to this item in the changelog for this version of gdm3:
* Drop 95_hide_x11_sessions_with_nvidia_kdms.patch: - No longer needed with nvidia-384 I noticed before this version that indeed, if I enabled modeset on nvidia-387 (which actually worked), I only saw the Wayland sessions in gdm, not the Xorg ones. I actually want Xorg sessions right now (For Reasons I Could Bore You With), but I thought I'd try enabling modeset again when I saw this. Instead what happens is, I see and can choose the Xorg sessions, but when I try to log in using GNOME on Xorg, it just returns back to the gdm login screen, after a pause of a few seconds. There's no obvious signs of an actual crash, in syslog or in /var/crash. I spot this though, during each attempted X session startup: Oct 11 12:39:07 fleetfoot gsd-xsettings[2515]: Failed to get current display configuration state: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Name "org.gnome.Mutter.DisplayConfig" does not exist and Oct 11 12:39:21 fleetfoot gnome-shell[2816]: Failed to apply DRM plane transform 0: Invalid argument Oct 11 12:39:21 fleetfoot gnome-shell[2816]: Failed to apply DRM plane transform 0: Invalid argument Oct 11 12:39:21 fleetfoot org.gnome.Shell.desktop[2816]: Disabling glamor and dri3, EGL setup failed Oct 11 12:39:21 fleetfoot org.gnome.Shell.desktop[2816]: Failed to initialize glamor, falling back to sw Wayland session appears to be working fine FWIW, with nvidia-387. But previously I did have a couple of random-seeming system hangs using it, which is one of the boring reasons I'm still preferring Xorg on nvidia.
