NVIDIA have released driver 319.82, and now 331.38, and they install OK on kernel 3.12, but – unfortunately – still need the patch for kernel 3.13, despite the fact that 3.13 Final is due in about a week from now..
modprobe: ERROR: could not insert 'nvidia': Unknown symbol in module, or unknown parameter (see dmesg) make: *** [package-install] Error 1
The patch is mentioned in a previous article: http://rglinuxtech.com/?p=948
With the patch, the drivers compile and install OK with 3.13-rc8..
