problem with nvidia driver: unable to close graphic enviroment for a console login

My Suse Linux 10.0 loads by default a graphic enviroment, and, after installing the nvidia driver, it is unable to close it. What it does:
1) when I shut down my computer, it should be displaying the closing operations, right? All it shows me is a screen filled with vertical pink and light blue lines!
2) the commands ctrl+alt+f1, ctrl+alt+f2 etc should take you to a console (tty1, tty2, etc) right? All I get is the same pink/blue vertical lines!
3) when I select console login, it displays the lines, it stays like this for a while, then it comes back to the graphic login thing!

It is, most certainly, a problem generated by the nvidia driver, because I didn't have it before I installed the driver, and I don't have it if I use the "nv" driver.

Any ideas what I can do about it? It's really annoying! I need my console, and xterm and konsole aren't enough! Thanks for reading, any ideas are appreciated!

It is certainly true that a graphic card driver can leave the graphic card in an uninitialized state when the driver unloads. You have several options.

1) When the system is booting and you see the GRUB screen you can edit the boot line to boot into run level 3. That is the text-only mode for the console. Then when you want to use the X system you can run the startx command from the command line in any user account.

2) You could stop the KDM or GDM or XDM graphic login manager and then press the <control><alt> and <backspace> keys simultaneously. That will stop the X session manager.

3) You could stop the KDM or GDM or XDM graphic login manager then start a terminal window and issue the 'init 3' command.

4) You could make a copy of /etc/inittab, then edit the original copy. Change the line that looks like this:
# The default runlevel is defined here
to look like this
# The default runlevel is defined here
Note that the last method may work the best because you never allow the Nvidia driver to initialize the graphic card. You may have to power cycle your computer to reinitialize your graphic card back to text mode.

Hmm, so the only solution is to boot into runlevel 3... I guess it should do for now.
Thanks for the advice.
