Comment 19 for bug 1705369


Sounds like GDM's KMS detection needs improving. Finding a KMS device is not sufficient for choosing Wayland over Xorg. GDM should be checking for a monitor plugged into the KMS device too. And if that's not found then fall back to Xorg.

Note that we can't simply make 'nomodeset' installed by default with Nvidia because that would break laptops. Laptops generally have their Intel GPU wired to the screen and the Nvidia GPU logically separate. But the fix to GDM I have suggested should work for all cases.
