I have a laptop with an nVidia 9300m GS 512mb graphics chip. When I install the nvidia drivers, either of the options (current or post release), it repeats my screen 6 times on the same screen, with grey bars separating them horizontally and a thicker black line vertically. How do I fix this?

Update:

it appears to believe it is a "separate X screen" with a resolution of 640x480 (won't let me set it higher, should be 1366x768) It recognises the chip and the laptop models exactly so should work.

Try removing the xorg conf file. See if it works.

sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

Reboot the system.

If above doesn't work, probably your graphics card is not supported any more.

Use x-updates ppa to get updated drivers.

Type in terminal,

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates      
sudo apt-get update && sudo apt-get upgrade 
sudo apt-get install nvidia-current

Or you can also use proprietary nvidia drivers from here(64bit) . However your product isn't listed here. It is 9300m GS & 9300m G
