You can instruct the OS to boot into a diffrent run level by editing the kernel line before you boot it in grub. It will affect only that boot.
I don't have the comand syntex infront of me, but a google for it should produce the info. -----Original Message----- From: Juan Ignacio Gaudio <jgau...@gmail.com> Date: Thu, 16 Dec 2010 12:06:31 To: <debian-user@lists.debian.org> Subject: Spontaneously aborting X startup during Linux boot process Hello, I broke my X (again) trying to install a graphics device driver on my Vostro 1000, so now I don't have video and the keyboard does not respond. I just need to be able to change to a console tty and restore the previous xorg.conf. But as X starts automatically I can't manage to do that before X crashes and I lose the keyboard again... do you know of a way of changing the runlevel to just console (no X) or aborting X startup during Linux boot process (some key combination or anything). I'm running Debian Lenny. Thanks!
