Installed Slack-11.0 with 2.4 kernel.
Everything OK.
Installed the current 2.6.18 kernel + sources.
This kernel recognizes my on board NIC (sky2).
All hardware is recognized with udev.
Have now installed:

Tried to compile NVidia with NVIDIA-Linux-x86-1.0-8762-pkg1.run
Error: unable to determine the version of the kernel source located in /lib/modules/2.6.18/source

Then tried to compile with NVIDIA-Linux-x86-1.0-5336-pkg1.run
It starts building the kernel but ends with: Unable to build NVidia kernel module

Any idea what's wrong?

Hi,

Try to run NVIDIA installer with option "--kernel-source-path=KERNEL-SOURCE-PATH".

example:
sh NVIDIA-Linux-x86-1.0-****-pkg1.run --kernel-source-path=/usr/src/linux-2.6.18

By the way, the latest stable driver version is 1.0-9629.

I've just looked at my system and /lib/modules/2.6.17.13/source is a symlink to /usr/src/linux-2.6.17.13

I would start by confirming that this symlink is correctly set up on your machine.

Thank you

link was OK : linux -> linux-2.6.18/

Downloaded NVIDIA-Linux-x86-1.0-8776 and compiled without problems.
