Re: nvidia driver fails to load with the kernel-2.6.10-1.741_FC3 kernel

Hi All,
I have installed fc3 x86_64 on my compaq R3000.
I have upgraded my kernel recently to
kernel-2.6.10-1.741_FC3 and reinstalled the NVIDIA
drivers. But whenever I type the "modprobe nvidia".
It gives me the error message:
nvidia: Unknown parameter `'
FATAL: Error inserting nvidia
(/lib/modules/2.6.10-1.741_FC3/kernel/drivers/video/nvidia.ko
): Unknown symbol in module, or unknown parameter (see
dmesg)

Has anybody faced the same problem ?

Thanks & Regards,
Biswadip.

For 2.6.10 kernels you should apply a couple of patches to the driver before installing it. You will need the latest driver from nVidia (6629)The patches are attached. To install them, just do the do the following:

cd /path/to/nvdriver_.run_file
./NVIDIA-Linux-x86-1.0-6629-pkg1.run --extract-only
cd NVIDIA-Linux-x56-1.0-6629-pkg1
patch -p0 -i /path/to/NVIDIA_kernel-1.0-6629-1165235.diff.txt
patch -p0 -i /path/to/NVIDIA_kernel-1.0-6629-1171869.diff.txt
su
passord:
./nvidia-installer

These are the patches posted at the Linux forums on nvnews.net.
