Gdm: on_display_added: assertion 'GDM_IS_REMOTE_DISPLAY (display)'fail

After a Gnome update I get this Error in my Journal.

Gdm: on_display_added: assertion 'GDM_IS_REMOTE_DISPLAY (display)' failed

Does anyone already know how to fix this problem ?

- I only use one single monitor and no remote access.

Should be fixed in GDM 47, or possibly GDM 46.3 if that becomes a thing.

See:
https://gitlab.gnome.org/GNOME/gdm/-/merge_requests/259

You could also build GDM 46.2 + cherrypick that commit, as it certainly looks cleanly backport-able.

EDIT: Fixed current/future GDM point versions.

Thanks, I'll wait for an update.

Now, I have GDM v. 46.2

Sorry for any confusion as I mangled the current/future point-release numbers! Fixed now.

Are you able to use the GUI at all or are you stuck in CLI?  I'm stuck in CLI and I don't want to wait for an update.

thank you.  your reply was a big help.  i had been debugging an issue that didn't exist.  once you replied i was able to refocus and find the actual issue.

I have a fresh install, GDM version is 46.2 and have this problem 9 out of 10 times when boot. I can manually restart it and works fine afterward. I wrote a shell script to automate it.

file /usr/local/sbin/ckgdm

#!/bin/bash
sleep 5
I=0
CK=5
while true; do
  [[ $I -gt $CK ]] && break
  sleep 5
  journalctl -b -ugdm |
    tail -3 |
    grep "Gdm: on_display_removed: assertion 'GDM_IS_REMOTE_DISPLAY (display)' failed$" >/dev/null 2>&1 && {
      systemctl restart gdm
      I=0
    }
  I=$((I + 1))
done
exit 0

and this service to start it when boot.
file /etc/systemd/system/ckgdm.service
