Description Tristan Miller 2016-03-18 11:37:23 UTC 
The "Display Configuration" section of the "Display and Monitor" module contains a button labelled "Unify outputs".  This button is always active, but from what I can tell it is effective only when there is more than one display.  I suggest that the button should be deactivated whenever there is only one display.

I am using System Settings 4.11.20 on KDE 4.14.9 as packaged by openSUSE 13.2.

Reproducible: Always
Comment 1 Kai Uwe Broulik 2016-03-18 11:59:34 UTC 
Shouldn't it also rather be a check box?
Comment 2 Tristan Miller 2016-03-18 13:06:32 UTC 
Yes, a checkbox seems more appropriate to me.  But again, it should be deactivated when there's only one display.
Comment 3 Sebastian Kügler 2016-03-18 14:11:09 UTC 
Not sure about the checkbox, the "unify outputs" just sync the size and position between the outputs, there's no such mode as "clone mode", so a checkbox would be misleading and make the whole thing less flexible.

Otherwise, yes, button should be disabled for only one output.
