After you have downloaded NVIDIA-Linux-x86-1.0-6629-pkg1.run, begin installation by exiting X, cd'ing into the directory containing the downloaded file, and run:
sh NVIDIA-Linux-x86-1.0-6629-pkg1.run
The .run file is a self-extracting archive. When the .run file is executed, it extracts the contents of the archive, and runs the contained `nvidia-installer` utility, which will walk you through installation of
the NVIDIA driver.
The .run file accepts many command line options. Here are a few of the more common options:
--info
Print embedded info about the .run file and exit.
--check
Check integrity of the archive and exit.
--extract-only
Extract the contents of ./NVIDIA-Linux-x86-1.0-6629.run, but do not run 'nvidia-installer'.
--help
Print usage information for the common command line options; and exit.
--advanced-options
Print usage information for the common command line options as well as the advanced options, and then exit.
Installation will also install the utility `nvidia-installer`, which may be later used to uninstall drivers, auto-download updated drivers, etc.
