I compiled my custom kernel, in RedHat Null.
It worked for my new kernel, doing this
"rpmbuild --rebuild NVIDIA_kernel-1.0-2960.src.rpm"
"rpmbuild --rebuild NVIDIA_GLX...."
and then, install it from /usr/src/redhat/RPMS/i386
1. Kernel not configured, and Nvidia_kernel will not compile
2. Diferent version, between Nvidia_kernel and kernel (ie. install it in 2.4.18-11custom instead of 2.4.18 ). Look your /lib/modules directories and version from /usr/src/linux/Makefile
3. if doesn't work, and you installed Nvidia driver, try to force it,
add "/sbin/insmod -f NVdriver" at the end of /etc/rc.d/rc.local
(Is not a valid solution, but work until you find where is the error)
4. I am not an linux expert, and my english is very bad. No more sugestions
