Nvidia driver install help?

I assume you started the run file by opening a terminal, cd'ing to the Downloads folder, and typing "./NVIDIA-Linux-x86_64-361.28.run" (or whatever yours is called). You could also type "sh ./NVIDIA-Linux-x86_64-361.28.run" . Adding the "sh " in front of the command would avoid a permissions problem if you are getting an error about that.

But - copy and paste everything that was output in the terminal after you typed the command. If there was a lot, just copy-and paste the last 20 or 30 lines at the end of the output.

FYI, every vendor seems to choose a different method to install drivers. Having a file called ".run" may be unique to Nvidia - just a way they chose to name it.
