Open a console.
Type in
su and hit enter
Type in the root password and hit enter
To the left of your blinking cursor, you will see that where before there was a '$' there is now a '#'. Any commands you now use in that console will be issued as if you were logged in as root.
You need to not be running X to install the driver. Assuming that you have an Nvidia card, follow the instructions here:
ftp://download.nvidia.com/XFree86/Li...106/README.txt
Sec02 states that you should exit X and set your runlevel to not be graphical.
In the console (as root), open your favourite text editor. Since you are used to using X, I would say open
kwrite. So type that in and hit enter.
When it opens, navigate to
/etc/inittab - file-->open.... Near the top you will see the runlevel you are using and an explanation of the various runlevels. Change the number you are using to the number for no X. Save the file.
Hit ctrl-alt-Fn (where n is a number of one of your function keys at the top of the keyboard) - I use F7, it may vary on your system. You will then find that you are in a text only system. With a login prompt. Login as root.
Navigate to the place you have saved your .run file (
cd /wherever/it/is) and run the file.
It may complain about a lack of source files for the kernel. If so, use
Urpmi to install them (this will work in the text only area you are in) and continue with the driver install.
