ok, I pressed alt-ctrl-f1 and it displayed my screen with a gui. I then pressed alt-ctrl-f2 and it displayed a textual desktop. I pressed alt-ctrl-f3 and it displayed the same thing. When I pressed alt-ctrl-f1 to return to my gui, it would not let me return to a gui. I was stuck in a cmd line textual desktop.
How, without restarting, do i return to a gui once I press alt-ctrl-f2??
