I downloaded Ubuntu 13.04 and I loaded up the live system. It loaded up fine but when I clicked on the Ubuntu logo purple and pink lines appeared on screen and they didn't go away so I thought that if I installed the OS it would be fine so I installed the OS, logged in and lo and behold the purple and pink lines where back.

My video card is nVidia N force (I think) Anyone having the same problem???

Graphics driver issues can cause the artifacts you describe. If this is a fresh install, I'd recommend running

sudo apt-get update && sudo apt-get upgrade

(to update the OS, including it's drivers)

and then going to "Additional drivers", at the start, and see what Ubuntu offers.

Now, to be completely honest, at my office we have 4 GeForce6100 cards (nForce chipset) and NONE of them work properly, with any driver, in Ubuntu 12.04. Using 3D mode causes random crashes that requiere logout/reboot, while 2D mode works OK.

We chose to stick to 2D using the current nvidia drivers (via sudo apt-get install nvidia-current and then sudo add-apt-repository ppa:x-swat && sudo apt-get update && sudo apt-get upgrade).

Good luck!

update your Nvidia driver. To do so, open a command terminal window, and type: sudo apt-get install nvidia-current press enter then type sudo apt-get install nvidia-current-updates press enter then, reboot
