I'm attempting to install Nvidia drivers on my system, to do this you need to shutdown x server, which I did, and I went through the installation process, however, now I cannot use a graphical interface, as it gives me a black screen. Is there something that can be done?

Type: 'ps aux | grep 'gdm'

kill any gdm processes

type: sudo 'gdm'

and how do I kill any of the KDM(kubuntu uses KDM) processes?

copy your nvidia drivers somewhere, lets say /usr/src. Then press for example ALT+CTRL+F2. now login as root and run this command:

killall kdm

now enter /usr/src and run nvidia installer. after that follow instructons on screen

cd /usr/src
chmod +x NV*
./NV*


oops sorry i misunderstoodm ;p

in my opinion your problem is with /etc/X11/xorg.conf
did you install that new nvidia driver on already existed driver or it was first ever nvidia installation in your OS?

It was the first nvidia install, but after it didn't work the first time, I tried reinstalling.

This is the text that comes up after the Kubuntu load screen:

Starting K Display Manager: KDM.

*Starting Avahi mDNS/DNS-SD Daemon avahi-daemon
*Starting Common Unix Printing system: cupsd
*Saned disabled; edit /etc/default/saned

mknod: missing operand after '1'

mknod: missing operand after '1'
Try 'mknod --help' for more information
*Checking battery state...

each line ends in [OK], except for the mknod lines

at the very least, is there some way to restore the default drivers so that I can at least use kubuntu?

edit /etc/X11/xorg.conf and in drivers section remove nvidia driver and put there vesa or nv.
