No nvidia driver support in a wayland session

This bug affects 9 people
Affects Status Importance Assigned to Milestone
nvidia-graphics-drivers-390 (Ubuntu)

Bug Description

Why not?
If I log into X11 then the nvidia drivers are used, if I log into wayland then it reverts to Intel.

I think this is correct. Nvidia disables KMS support by default, which means no wayland support.

It is documented (with a workaround) here:

Correct but now in 18.04 KMS can no longer be set in the combo of
Ubuntu's 4.15 kernel & nvidia drivers.
See here

This prevents use of nvidia on wayland & per bug prevents prime sync in
an X11 sessions, both of which are going to be a bit of a disappointment
for many 18.04 users.

@Doug: if you're using a hybrid system, then I think Wayland will use your Intel card, but you should still be able to use the discrete GPU for some applications (at least in the next GNOME release).

And I am working on LP: #1752739

What was quite 'odd' is the day I filed this was a fresh install, updated, then installed nvidia-drivers (390.x), rebooted
For about 2 days it was as described, log into xserver got nvidia, log into wayland got intel.
Then, for no apparent reason on boot up the option to log into wayland disappeared. The only way to get it back was to remove the bulk of the nvidia driver packages.

Recent fresh installs now act as the later, with nvidia drivers installed there is no option for wayland.
Is it expected that a wayland option should always be available or is it 'blacklisted' in some fashion in the presence of nvidia drivers?
