I had some trouble once I’d installed steam. It would fail to find the swrast driver. After some searching I found that the following command pulled through the required libraries:
sudo dnf install xorg-x11-drv-nvidia-libs.i686
This didn’t work quite so well on Fedora 23 so try this…
sudo dnf install nvidia-driver-libs
or use yumex-dnf to install nvidia-driver-libs.
After installing akmod-nividia package, you might run into a situation where you install a shiny new kernel but the akmod-nvidia package builds, but doesn’t install the drivers for the Kernel. To get it to install your built drivers do this:
cd /var/cache/akmods/nvidia; ls
sudo rpm -ivh kmod-nvidia-###########.rpm
sudo shutdown -r now
Where ############ is the latest number that corresponds to your new kernel number and the driver version.
You might want to check out the fail log to see why it failed. When this happened to me akmod had tried to install, but rpm was locked.
