I'm using ubuntu 12.10 gnome3. I have a projector and 2 laptops (Ubuntu and an Apple) In between a switchbox to manually switch from Apple to Ubuntu and vice versa.
What happens is that when switching to the Apple, Ubuntu forces the second screen back to the laptop (primary screen). When switching back to Ubuntu I have to drag my browser back to the projector screen and use F11 to maximize it. I would liek my audience not to see these handlings.
So I would like Ubuntu to keep the settings of the projector, even if it's not connected.
In ubuntu 10.10 this works. Only at startup I have to use the display menu to find the beamer and when I arrange the browser fullscreen to the beamer I can use the switch to go to the other source and back without losing the fullscreen browser.
I've tried some things, hope someone can help me further...
