FWIW, the only reason I use akmods is for installation of the nvidia module when a new kernel is available. I don't do auto updates so I simply check /var/cache/akmods/akmods.log to make sure I see something similar to.... 22 Dec 10:05:25 akmods: Checking kmods exist for 3.12.5-200.fc19.x86_64 22 Dec 10:05:26 akmods: Building and installing nvidia-304xx-kmod 22 Dec 10:05:26 akmods: Building RPM using the command '/bin/akmodsbuild --target x86_64 --kernels 3.12.5-200.fc19.x86_64 /usr/src/akmods/nvidia-304xx-kmod.latest' 22 Dec 10:05:43 akmods: Installing newly built rpms 22 Dec 10:05:52 akmods: Successful. is recorded when a new kernel is installed. -- Getting tired of non-Fedora discussions and self-serving posts
