I think you need to set up your /etc/X11/xorg.conf properly.

Open up the terminal and type:

sudo nano /etc/X11/xorg.conf

Enter your password.

Then add the following to the section called Device :
(if the section isn't present, just type it down at the end of file)

Section "Device"
	Identifier	"Configured Video Device"
	Driver		"nvidia"
EndSection

When you are done press CTRL + X to save and close the file.
Restart and the driver should be working.

The first thing to do is decide which driver set (Kubuntu's or the one's from nvidia's website) and don't ever install both. They do not install to the same location and therefore are not compatible with each other. If you decide to use the nvidia website driver, you will need to get instructions from their forum.

If you decide to use the Kubuntu supplied nvidia driver, make sure your have the kernel headers installed along with the kernel. Then, you can verify the driver is available by typing dkms status in a terminal window. The ouput will have the driver(s) listed and their status. If it says anything other than "installed" the driver is not ready to be used. You must reboot before the driver is available.

Once you have the driver installed, open a terminal again and type sudo nvidia-xconfigure and this should create a usable (but very basic) /etc/X11/xorg.conf file. Then type sudo service kdm restart and you should be up and running after you log back in. You'll see nvidia-settings in your menu under Settings so you can change the resolution if needed and some other basic stuff.
