I rm /etc/init/tty4-6 couse ill need only 3 max to get support in case of real import job loosing.
I have laptop Dell D610 & LG Flatron L197WH
I think before i deleted thouse TTY it was working back and forth or maybe it was tested with one monitor- dont remmember exactly.
But now with monitor attached i can get in TTY1 TTY2 TYY3 but on TTY7 keyboard freezes monitor black freezes and no response anymore only cold shutdown helps.
