I've got an nvidia tnt1, redhat 6.2 with X4.01 running. I seem to have gotten the X kernal driver up and running just fine. Got NVIDIA_kernel-0.9-5.tar.gz ran the install script changed one line in my XF86Config and off I went. The GLX driver is another matter entirely. I blew out the links to various libGL.so.*'s as per the faqs request and ran a make; make install (they seem to have done the same thing) and added Load "glx" to my XF86Config, but quake2 just crashes with a segmentation fault. What's more an app I got with the SDL graphics library called testgl reports I've got no Opengl support. Maybe I blew out something I shouldn't have, but I'm pretty sure I didn't do anything that wasn't in the FAQ from nvidia, and if I did I'd have expected the GLX install script to put it back (or at least I'd expect and error about a missing file, not just a segmentation fault). I know the TNT_USERS_README mentions a problem with memory and mentions os-registry.c. But that file isn't in the GLX tar, was it in the kernel driver tar (which I've since deleted). Any help would be appreciated, since I'm way over my head here. Thanks in advance :-).
