Comment 0 for bug 1733136

I upgraded to 18.04 and I no longer get an option to run a wayland session (17.10 offered both the default ubuntu wayland session and xorg on this laptop).

The upgrade did force me to remove bumblebee and nvidia, but afterwards I manually reinstalled bumblebee and nvidia-387 and reset to using intel via prime-select (installing nvidia changes some of the symlinks so that gnome-shell no longer boots, but "sudo prime-select intel" fixes this).

The nvidia-387 modules are blacklisted in /etc/modprobe.d, and bumblebee isn't reporting any errors - bbswitch reports that the nvidia card is off, so I don't think it's an issue with hybrid graphics. (primusrun does work, as well.)

Attached are the mutter logs that I generated via the environment variables mentioned in https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1724583 comment #20. I suspect that the culprit is hinted at in this message:
