gdm3 cannot login to plasma wayland on nvidia 470.63.01

[Luiz Angelo Daros de Luca]

Hello,

My KDE wayland session does work if I launch it from CLI using startplasma-wayland.
However, when I login from gdm3, I got some form of session crashes and I am back to gdm3 screen a couple of seconds after I inform my password.

The X11 session is working as expected. The weirdest thing is that "plasma wayland from gdm3" will work after I log, at least once in that system uptime, to a plasma-x11 session. Something like this:

system boot
log to plasma (wayland) from gdm3
after some screen blinks, I'm back to gdm3
log to plasma (wayland) from gdm3
after some screen blinks, I'm back to gdm3
log to plasma (wayland) from gdm3
after some screen blinks, I'm back to gdm3
log to plasma (x11) from gdm3
session is good
logout
log to plasma (wayland) from gdm3
session is good

It looks like "plasma x11" left something configured/running that allows a following wayland session to run.
