Comment 72 for bug 1968929

funny enough, I have the opposite issue, 22.04 w/ gdm3 42.0-1ubuntu7 installed and Nvidia 510 driver. Hardware is a Dell XPS 15 9510 w/ GeForce RTX 3050 Ti Laptop GPU.

When selecting the Nvidia "On-Demand" profile, I get both, Wayland and X11 in GDM. However, when I select "Performance Mode", X11 stops from working, it's not offered in the gear menu anymore. What's worse, even if I disable Wayland in /etc/gdm3/custom.conf, it seems like the X server simply crashes:

Is this a separate / known issue?
