I tried for a couple of days to get the NVidia drivers to work with 2013.02 - no luck.
Could only get it to work with Vesa.
Xorg.config setup can't find [nvidia.so] among other problems, so reloaded / updated 2012.12 and it is working ok.
The 2013.02 ISOs shipped with nvidia173-14.36
-1 which is broken (fails to load module nvidia.so).
This package has been removed from the repo.
Depending on whether you are using
PASS or the public mirrors you will have either:
nvidia173-14.36
-2 or
nvidia173-14.31.1
available for installation. Either of these will work with FX series cards.
If using public mirrors you will need to remove the nvidia173 packages and then you will see nvidia173-14.31.1 available for installation.
(Hopefully 173.14.36-2 will make it to the public mirrors soon
