I did a presentation with my laptop with an external monitor (using latest Xubuntu). After the end of the presentation my laptop ran out of battery. When I got home an logged in again, I had only a desktop picture and no desktop, and figured the system is still set to display the desktop on an external monitor....
I'm travelling around at the moment and don't really have access to another external monitor to fix the problem, and need some of the files in my account.
Are there any keyboard short cuts or anything that could potentially help me out?
Many thanks in advance!
