2D works out of the box on Fedora Core 2 with X.org 6.7.0. The install process completed and booted to a Gnome desktop without any special configuration. Enabling 3D acceleration requires installing a closed source driver from NVidia. Although installing the driver was not a problem for me, it is an extra step. Fully open drivers can be packaged with a distribution and generally work without additional configuration. Because of the extra configuration required compared to cards that have fully open 3D acceleration, I give the card an 8 even though it is stable and performs well (subjectively, I've done no benchmarking).

ENABLING 3D ACCELERATION USING YUM AND LIVNA.ORG

In order to enable 3D acceleration I installed the kernel modules from livna.org. The advantage of doing this is that the NVidia modules are package managed and maintained in sync with new kernel packages. By the time I did this I had already set up yum to work with the Livna repositories, and after installing the package no additional configuration was required (no kernel recompile, no editing xorg configs).

The unofficial Fedora FAQ has instructions:

If you aren't already using the livna.org repositories with yum, then don't miss the links included in the nvidia answer explaining how to set that up. First a brief explanation of how to use yum:

Then an excellent yum config file, I was able to copy this into /etc and go:

ENABLING 3D ACCELERATION USING THE NVIDIA INSTALLER

Nvidia also provides a driver installer which supports many of their cards and allegedly works with most distributions. I haven't used it, but it is available at:

The current x86 driver as of 9/29/04 claims support support for the Quadro2 Pro:
