Re: GTK2 + NVIDIA Modules ( Please Help )
Try gentoo linux if you reinstall. I got a AMD64 and I use gnome 2.4, everything works great. As far as the Xfree86 I thought that you had the module as "nv" at first but I found out you had the "nvidia" module (which is the correct module) installed instead. The driver should also be named "nvidia". If you need any help with installing gentoo let me know. Gentoo also has a great forum where you could ask questions.
I use GTK 2.2 works like a charm.
