In the past 3-4 months I've noticed that on the main site, there is a ratio of about 5:1 referring Nvidia graphics questions than anything else, and I'm wondering why? I do understand that NVidia being a very large distributor, there will be more people asking questions, but even with comparison to questions relating FGLRX (Or even AMD cards in general,) NVidia are around 8x more prominent and visible. Is this because NVidia drivers are more complicated, or that less people use AMD? It's also getting annoying with the 100 questions a day on the same "NVIDIA DRIVERS NOT INSTALLING.. HELLLLLPPPPPPPP" and then marking duplicate after duplicate. This is a kind of rant, and I'm sorry for that but I really don't know why so many people have questions on NVidia!
Well, people who have no experience with Ubuntu think "I know! I'll install Ubuntu," and then it all goes downhill from there.
In all seriousness, though, I think it's a mix between inexperienced users coming to Ubuntu, the popularity of NVIDIA and the fact that NVIDIA cards tend to have bad times on Ubuntu. For whatever reason, the proprietary drivers sometimes don't work, and the generic ones sometimes fail as well.
Because NVIDIA is so popular, a lot of people using Windows have the brand. When they decide to install Ubuntu, whether because they used it sometime in the past or because they like the look of it, there's a high chance they'll have problems with NVIDIA and Ubuntu. (Sorry for the redundancy)
inexperienced/new users +
NVIDIA's popularity +
NVIDIA's trouble with Ubuntu =
many NVIDIA & Ubuntu questions.
