gnome-control-center display 'Move gnome-panel' doesn't work

[Luis Carlos Cobo]

I have a setup of a laptop with two screens, one in landscape mode, one in portrait mode. When I connect the two screens, the gnome-panel goes to one of them (in the few days I've been running Trusty it seems more or less random to which screen the panel goes).

I don't care much where the panel goes, but sometimes the panel is in the landscape screen and takes only half the screen, or it is in the portrait screen and takes more than the physical width of the screen (so some icons are unreachable). When this happens, if I open gnome-control-center -> display, it 'thinks' that the panel is on the other screen (where that panel length would be correct). If I move the panel on gnome-control-center to the 'correct' screen, the panel gets the right length. If I move it back to the other screen, the panel stays in the same panel but goes back to the wrong 'length'.

In short, moving the gnome-panel representation on gnome-control-center screen diagram makes gnome-panel adapt to the length of the screen you move it to, but the actual panel does not move from the screen where it is.

Let me know if you need any other info, thanks!
