When disconnecting the 2nd display, first the application windows move the built-in laptop display, but after one or two seconds the screen went gray, telling me that an error has occured and that you need to log in again. I went through the journalctl, and noticed lots of messages as below: Attempting to call back into JSAPI during the sweeping phase of GC. This is most likely caused by not destroying a Clutter actor or Gtk+ widget with ::destroy signals connected, but can also be caused by using the destroy(), dispose(), or remove() vfuncs. Because it would crash the application, it has been blocked and the JS callback not invoked. Not sure if this is the actual cause though. After some googling I found bug report #1857660 in which it was suggested to uninstall a few gnome extensions. One of the mentioned extensions was indeed installed, but I removed (in the end) all of them, rebooted but still problem occurs. And is reproducable in a very simple way: - Reboot & Login (with 2nd monitor attached) - Open an app (not sure this is really needed to reproduce though) - Disconnect the 2nd display and wait a second. - Boom! Useful to mention that the problem does not occur on Wayland, even with the extensions installed (but with Wayland I can't share my full screen, which I need for Slack :-( ).
