Łukasz, Yes, just opening the Sharing panel with gnome-control-center 1:41.4-1ubuntu12 is enough to attempt to start the RDP service. systemctl --user status gnome-remote-desktop reports this error:
RDP TLS certificate and key not configured properly I didn't check open ports but it makes sense that it would open the RDP port even though the RDP service isn't completely working. ** Description changed: - Summary - ======= - 1.

(Probably would show up for any new user.) - - 1. Before opening the Settings app, the gnome-remote-desktop service is - running.

That tells us - whether RDP is running or not. There would be a similar line for VNC. - This line didn't show in the initial state in step 1. - - What should happen - ================== - Remote Desktop should show off by default and should not attempt to turn on just by opening the Sharing page. - - There is no gsettings for the Sharing master on/off switch (in the - headerbar). It shows as On if any of the services are On. None of the - services should be On by default so this should show Off by default. - - A Bug Trigger - ============= - It looks like this bug was triggered by - https://gitlab.gnome.org/GNOME/gnome-remote-desktop/-/commit/7f4ef31fd3 - - I have reported this issue to GNOME. That patch fixes an important issue - so maybe we need to keep that patch but fix the logic in gnome-control- - center. + To simplify this bug report, I removed a lot of troubleshooting details that can still be seen with the "See full activity log" link ** Description changed: Impact ====== 1.
