Re: NVidia binary driver wrongly has been displaying 50Hz since 9xxx drivers
I used to worry about the refresh rate thing, until I realized it was merely cosmetic.
I'm not really clear on what the other parts of your comment refer to so I won't go further.
Any distribution that wants to can create a working nvidia installer, it's fairly trivial, just find someone willing to do the dirty work and that's it, one person maintains it, the users use it. Like anything else done with programming, no need to keep typing the same stuff over and over, just put it into a script then run the script, hardly rocket science.
