When I ran to Nvidia's website to download their 64bit Linux drivers, it downloaded a file named "NVIDIA-Linux-x86_64-319.49.run". Since this wasn't a file extension I'd seen before, I assumed double clicking would do nothing (Incorrect; it actually tried opening it in a word processor which hilariously meets with a crashed word processor).
I installed new drivers through a terminal. For future reference, however, assuming this is an archive, and clearly Nvidia expects everyone to be able to crack it open on command, how would I go about making the .run file actually be useful? Was there a command to decompress it and install the drivers? Was it a script and I just have no idea how to execute it?
(Very new to Linux; Ubuntu's my first attempt at running a distro since ...oh, RedHat 6.something. Anyways, so much for context.)
