Comment 11 for bug 216144

Even thought the gnome bug has been closed as fixed in Gnome 3, the solution of having to drag the "menu bar" to another monitor seems suboptimal to me.

Whenever I hook up an external monitor to my laptop, and have to explicitly enable it (because I disabled it before) in the Monitor Preferences, I really want to make it the primary monitor in that same dialog. A checkbox, as proposed elsewhere, that does the same thing as "xrandr --output VGA1 --primary", along with some kind of marking in the monitor arrangement panel.
