I need to close x server, how?
 

I need to close x server to install nvidia driver updates, any clue on how to do this

Go to the first virtual console with Ctrl+Alt+F1. Login as root and type

# init 3

to switch to single user command line mode. Update your driver (as
described in README or somewhere else, I don't know :)). Then type

# init 5

ctrl+alt+backspace. That will shutdown/restart the X server. If you booted into X, then it'll restart, but if you booted into command line, it'll drop you back to it. If you boot into X which i'll assume you do since you're running mandrake, change /etc/inittab line from

id:3:initdefault:
to
id:5:initdefault:

there should be a a guide at the top to help you out just in case 5's the wrong number.

Press CTRL-ALT-F2, log in as root, then type in /sbin/init 3. That will put you in text mode ready for the nVidia install.

You don't even need to press ctrl-alt-f2. If you type it in a terminal window (as root) that'll kill your X server just as well.

su to root inside of X and typing "/sbin/telinit 3" also works.

Ok I did that and it brought me to this big terminal, and I need to CD to my home directory but dont know how... I triec cd root/robert/home...didnt work

If anyone knows how to CD to my home directory after shutting of the x server it would be nice :)

If your user name is robert:

cd /home/robert

should do the trick.

you can just type
cd
and then type
pwd
that'll show you that you're at home.
Nice thing about UNIX... they make it easy sometimes for us lazy types :) typing "cd" automagically sends you home, like clickin your red shoe heels three times :))))
