Re: FATAL: Module nvidia_1_0_8178 not found
Back with more info.
I removed the lian 2.6.14-1.1656_FC4 Red Hat Fedora Core kernel that I just downloaded, init'd to Run Level 3 and re ran the nvidia NVIDIA-Linux-x86-1.0-8178-pkg1.run installation script, while happily running with 2.6.14-1.1653_FC4 kernel from Fedora Core update.
No probems this time. NVIDIA X Server Settings gui reports all OK and using driver 1.0-8178. I re-used my old xorg.conf which has twin view settings in it and which doesn't have a ModulesPath call out.
So I conclude nothing is amiss with the nvidia end of this. I'm finding fault with the latest kernel upgrade (the 2.6.14-1.1656_FC4).
I'll try creating a 8178 kernel interface for the 1656 kernel later.
