I'm running Gnome-shell GNOME/openbox, not Unity, on a dual display.

My top and bottom panels are always on my laptop screen. I really want them on the external monitor when that is plugged in. I've read a ton of tips about using gconftool-2 and gconf-editor to switch the "monitor" key from 0 to 1 for each panel, but doing that has no effect.

I can use alt super right to access the panel properties and move the panel to the top / left / right / bottom of my laptop screen, but I can't for the life of me move it over to my external monitor.

I recently rearranged my desk and don't know what all I customized six months ago when I was setting up my desktop environment. So one question is ... could I have done something to give control over my panels to something other than gconf-editor? How would I figure that out?

Thanks!
