Editor stuck on laptop screen, cant move to primary monitor

Hi,
Just coming back to Unity and installed 5.6.2 onto Fedora 25 Gnome desktop on the laptop. After starting the editor it moves to the laptop monitor in what appears to be fullscreen mode and wont move to either of the other bigger monitors. Does anyone have a clue please?

Cheers,

Michael

Ah, turned the monitor off and now can move it anywhere. Ignore me please
