As I'm obviously stupid, I don't know what you're after, because the AMD64 version of the nvidia driver is here
Plus, if you're new at this "linux lark", then the best resource you've got (already) is the urpmi package manager. That's usually found in configure my computer>software manager>rpmdrake+ .
With that in mind, open a terminal/konsole (whatever you want to call it - the TV screen like icon at the bottom of your display), you should have a command prompt like bash-2.05b$ or maybe Legacyc @ Legacycs pc $ (in other words it usually had a $ prompt for command line completion).
With that open, type in su (just the letters) and hit enter, then put in your root password when asked and enter.
Minimise that. Then go to this site
, and follow the instructions to the letter i.e. everything, from your architecture right the way down, ticking the boxes for all the sources and selecting a source from as close (geographically) to you as possible (in theory the closer the source, the faster the download). The only thing that I never bothered with was the compressed index and media source names (the very last boxes before stage 3).
When you've done that, and hit the stage 3 button, you just copy and paste the info from the output box in 3), to your terminal/konsole. Sometimes it would start automatically sometimes I had to hit enter after the copy/paste.
Then let it do it's thing.
If you then re-visit your software manager and look at what's available in the rpmdrake + boxes you'll be suprised what's available - I'd guess, that if "apt" has been ported/mandrakised, then it would be available there. If so, use that source as URPMI should do full dependency checks etc when it starts the download/install process.
Or, you can just follow the instructions that you find at the nvidia site, download both the driver and the readme. The readme has full instructions on how to install the driver.
Good luck !
