I'm sorry if I seemed fired up - I wasn't, just overdue for my morning brew. You see, I'm supposed to uphold and maintain those Guidelines and there's that one that says: "Write in English". That's why I trashed your post. Guess I should have realized why you posted that way but I thought you'd started in Spanish and then switched over to English and maybe didn't know how to delete it..and...oh I don't know what the hell I was thinking, obviously not much.
And as to your cards, prior to this I'd always simply downloaded the Nvidia drivers (not yours though) and then did the old 'kill X', 'sh *.run' and let Nvidia build it for me. Now, that simply won't work with the architecture of FC5. So, I'm banking on the Livna group to come out with suitable drivers for every version of the Nvidia cards and, if 'yes' is right on about page 6-8 of Firewing1's thread, those drivers may already be in the development section of Livna's repository.
Another suggestion would be to tack a request for help on that card to the end of Firewing1's thread. The guy is always willing to work out problems and is one of the best coders that I know of. If there's a solution, I think he's the one to find it.
Now, all that typing has made me thirsty again. Time for a brew!
