I don't think you need the updates - testing repo anymore. I just installed the 340xx driver the other day, on a box with a GeForce 8600, and it worked fine.  -------- Original message -------- From: Roderick Johnstone <rmj(a)ast.cam.ac.uk&gt; Date:03/02/2015 6:12 AM (GMT-05:00) To: rpmfusion-users(a)lists.rpmfusion.org Cc: Subject: Re: nvidia kernel modules and drivers for F20 Mike/Nicolas Thanks for your suggestions. I was able to resolve this with: For systems with older grahics cards: yum erase xorg-x11-drv-nvidia yum --enablerepo=rpmfusion-nonfree-updates-testing install akmod-nvidia-340xx akmods --kernel 3.18.7-100.fc20.x86_64 For systems with newer graphics cards: yum erase xorg-x11-drv-nvidia-340xx akmods --kernel 3.18.7-100.fc20.x86_64 I just run the akmods commands by hand to be sure that the kmod will be built ok before rebooting.
