Hello,

I found the "$XDG_SESSION_TYPE" is defined to the value "X11" when no screen is plug to the computer video card.
The $XDG_SESSION_TYPE" value is back to "wayland" when the gdm.service is restarted manually, and everything is working fine again.
systemctl restart gdm.service

It seems there is a service startup issue between the dispalylink-driver.service service and the gdm.service despite the dispalylink-driver.service is defined to run before the gdm.service

systemctl list-dependencies gdm.service --before
Quote:
gdm.service
● ├─displaylink-driver.service
● ├─graphical.target
○ │ ├─systemd-update-utmp-runlevel.service
○ │ └─shutdown.target
○ └─shutdown.target
May the USB / displaylink the not fully initialized yet when the gdm starts ?
