Comment 38 for bug 2060268

Isn't this also a Gnome settings bug? Even with the presence of an erroneously detected extra monitor, shouldn't we be able to simply deactivate it / configure the desktop to not span across both monitors?

The Settings > Displays GUI doesn't seem to work correctly. The "Unknown" monitor is reported as being inactive, although we can see the effects of e.g. the mouse pointer getting lost on the right. Activating/deactivating the "Unknown" monitor also doesn't work.
