I noticed I couldn't comfortably swith to X (tty7) from say TTY1 in Linuxmint 12 and 13(I haven't tried 14 yet). On switching to TTY7 through Ctrl+Alt+F7, I get a blank(black?) screen and am forced to 'kill' Xorg from the command-line of another TTY which bring s me to the log screen. I have never figured what the problem is. Anybody?
when life gives you a run, give it a break. retreat is a tactic not defeat!
