Problems installing Debian

[satinoctopus]

It seems I've finished installing Debian 3.0r4 from CD
But when I start up the machine, I get a graphical login screen where I've tried with the two users I defined in installation, one of them root, and I get a message in the right bottom corner saying "can't locate module char-major-13"
I can't do anything, because if I can't login I can't edit, reinstall or configure anything.
Any hint?
Thanks a lot in advance

Is there a way for you to log in non-graphically? According to this thread, this is apparently caused by a problem with xdm, and can be fixed by removing xdm and reinstalling it. In order to do that however, you must be able to log in non-graphically.

Did you install GRUB or LILO as a bootloader?

to login non-graphically from debian's gdm or xdm, i think it defaults solely to gdm now...just hit ctl-alt-f1 at the graphical login and you will change vts and be a non-graphical login. If you can login as root, then stop the graphical service with, if its gdm "/etc/init.d/gdm stop" and then login as a non-root user and see if startx works, if so then it is just a borking of your dm. Tell us if this clears things up, if so, just reinstall gdm if you want it, if not, startx is only one little command away

I didn't know I could enter in text mode by means ofCtrl+Alt+F1
It works, but startx doesn't work. I get theses lines on the screen:

Xlib: connection to ".0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
giving up.
xinit: unable to connect to X server
xinit: No such process (errno 3): Server error.

I found in another forum that someone fixed this problem by adding Off in the DPMS Option of /etc/X11/XF86Config-4 file
I did the same and then, the login process could proceed

Thank you both for your answers
