Any of you uses Fedora with an Nvidia-GPU?
The distro seems pretty cool, but i doubt I'll get everything to work, since fedora doesn't offer premade packages for proprietary drivers.

RPMFusion is your friend :)

I used to, years ago, before my GTX 560 TI burnt out and I switched to AMD (Haven't had an NVidia since).

I remember that NVidia had their driver available for Linux, but while it installed, anything beyond basic 3D acceleration (OpenCL etc) did not work for me.

Try the nuoveau driver (is that how it's spelt), I heard good things about it, but back when I needed it, my card was not supported for some reason (it probably is today, this was years ago).

Yes. I have fedora box with integrated intel graphics and nvidia. Somehow managed to switch off intel and use nvidia. Though original intention could have been to seamlessly move between intel and nvidia based on load. I think possible in linux (bumblebee?). Didn't investigate further.
