I just installed a new motherboard for my computer (Asus M2N68-VM) My screen resolution is 800x600 I went to the Nvidia site and downloaded a file to install the drivers (NVIDIA-Linux-x86-177.80-pkg1.run). How can I install this file? The instructions on the Nvidia site say:

Type "sh NVIDIA-Linux-x86-177.80-pkg1.run" to install the driver.

When I do this, this is what I get. This file is on my desktop.

randy@randyubuntu:~$ sh NVIDIA-Linux-x86-177.80-pkg1.run
sh: Can't open NVIDIA-Linux-x86-177.80-pkg1.run

What should I do? Am I installing the right file? Is there something I need to do after installing this motherboard? Please help. My screen size is way too large.

Thanks!!!
