** Summary changed:
- gnome-shell no longer offers wayland session in Ubuntu 18.04
+ wayland session in Ubuntu 18.04 chooses vmware driver on intel hardware
** Description changed:
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).
+
+ gnome-shell runs under the llvmpipe driver. (Unity used to run when I
+ first upgraded, but now gnome-shell is the only option because the gdm
+ login screen offers no login options.)
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:
