I can for certain tell you it does not as in such case gdm would
repeatedly restart of my computer which is doesn't. Please refrain
from these misleading incorrect statements. This will only
lead to a wild goose chase.

I assume this means you lack a KMS capable graphics driver and as
such gdm falls back to running X on your computer instead of
wayland. Can you please check if this is the case and if so
please provide the revelant /var/log/Xorg.0.log ?

Please also provide the gdm crash log.

For the future you'll want to make sure to have a KMS/wayland
capable graphics driver for your system.
