Public bug reported: I have a Nvidia GTX 670. I tried the nouveau driver. At boot, it takes a unusual long time then finally shows me gdm3 and everything is working after. But echo $XDG_SESSION_TYPE is set to "x11". Reading the logs, I can see that after multiple failures to launch wayland, it falls back to X11.
I added an attachement of journalctl -b -1 where it fails with nouveau (I'm filling the bug after reinstalling nvidia proprietary driver). lspci -v 01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 670] (rev a1) (prog-if 00 [VGA controller]) Subsystem: eVga.com.
