I'm trying to connect remotely with other debian computer with this method 'http://sowingstars.wordpress.com/2012/04/15/remote-graphical-desktop-session/'. Initially everything works fine, i could connect with the computer and begin a new session. But when I was trying to return to my ubuntu desktop using Ctrl-Alt-F7 the computer screen turns black and shows "No signal" and then the computer doesn't reply anything to other keyboard combinations.

I used other combinations after that like Ctrl-Alt-F1 and trying to return with Ctrl-Alt-F7 and I get the same trouble.

Anybody has a solution or other idea to open remote graphical sessions?
