And I only saw your feedback after I put my last comment in... :O
The lspci -k command run from artful shows this:
01:00.0 3D controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Mobile] (rev
ff)
Kernel modules: nvidiafb, nouveau, nvidia_387_drm, nvidia_387
I've got all those blacklisted though in /etc/modprobe.d/, and
"lsmod|grep nvidia" and lsmod|grep nouveau" both return an empty string.
(The configuration is pretty much the same in bionic as in artful.)
I can't disable the discrete GPU in my BIOS, btw. bumblebee works fine
in artful, though, turning off and hiding the nvidia card from gnome-
shell, and primus runs an X session using the nvidia card quite happily
from within gnome-shell, both under Wayland and X.
I guess I should go back to bionic and blacklist nouveau as well as re-
remove the nvidia driver and try again? Perhaps nouveau was being loaded
when I tried last time.

Title:
wayland session in Ubuntu 18.04 chooses LLVMpipe software driver on
hybrid graphics system
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
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
