Comment 12 for bug 1705369

"The first try, grub had nomodeset in it, and the system was able to boot, the wayland session was filtered out."

That sounds like a fix, and an answer to comment #8...? Does that mean you didn't need to disable wayland in /etc/gdm3/custom.conf ? Please clarify if you have a configuration that works and point out what it is for other Nvidia users.
