@erisdckw Could you please describe your setup bit more in detail. Lets start with the image you have used. Can you share the output of following command
$ cat /etc/*release
$ cat /etc/*version
Also are you using vim4 connected to a monitor, or are you using it headless using something like gnome-remote-desktop, vnc or something else?
Also could you please share the logs
$ journalctl >journal.log
Share the journal.log file created from about command. Make sure to capture the logs after reproducing the issue.
I would also try to reproduce it on my side and get back with the results.
@erisdckw Try editing /usr/local/bin/hdmitx_hpd_event.sh and change systemctl restart gdm3 at line 45 to systemctl reload gdm3. That should fix the issue.
