Comment 1 for bug 138319

Michael:
There's not quite enough information here to diagnose your problem. nvidia-glx (which corresponds to the 96xx drivers) will not work with your card (due to your cards newness - see https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia ). In theory nvidia-glx-new should work but you may be running into a known issue. Can you please attach the your
/var/log/Xorg.0.log
file that is produced directly after using the nvidia-glx-new driver (you may need to reboot to ensure you are using this 100 series driver) with nvidia in your xorg.conf?
