Would you explain the difference please? And what is the sequence
to change to akmod?
Sure.... The kmod-nvidia packages on your system contain the actual kernel modules
for the nvidia cards. With 3 kernels installed on my system I see...
[egreshko@meimei ~]$ rpm -qa | grep ^kmod-nvidia
If you don't have akmod-nvidia installed on your system and you get a kernel update
from the fedora repo but the rpmfusion doesn't have the corresponding kmod-nvidia you
will have to wait until they do....as you know.
But, if you install the akmod-nvidia package with supports your HW you won't have to
wait as it will build and install the needed kmod-nvidia when the kernel is updated.
akmod-nvidia-375.66-3 supports the latest nvidia hardware but there are also
other versions to support earlier HW. My older laptop has
akmod-nvidia-340xx-340.102-3 due to the older HW.
All you need do is install the appropriate akmod-nvidia package and the required
dependencies will be installed.

It's the 'silent' that bugs me and makes me ask WHY :-)
I think it has to do with the difficulty in putting out messages in the asynchronous
environment in which the packages are built/installed. However, it is easy to check
if all is well by just doing a "tailf" on /var/cache/akmods/akmods.log during
after the kernel update and wait for "success" such as this....
