> gnome-shell[30907]: Failed to create backend: No resources
I don't think that's an error. It's just telling you the Nvidia driver doesn't support Wayland (which always gets tried first). In theory gdm3 is then meant to drop back to Xorg in this case (as Seb says). But some Nvidia users (including Laney) have reported that this fallback doesn't work for them:

So this bug is possibly a duplicate of one of those.
Please try this as a workaround: edit /etc/gdm3/ custom. conf and uncomment the line:
#WaylandEnab le=false
Reboot, and if that fixes the problem then it appears to be a duplicate of bug 1798790.
