My question is, what is the difference between the kmp-default and kmp-pae kernel modules and how do I tell which one I’m using? Also what is the x11-video-nvidia package used for? Which of these packages do I have to uninstall if I want to try and install the nvidia driver manually?
Nooooo… x11-video-nvidia is the Xorg component needed to interface with the kernel driver. This is required.
It’s strange that you would have both installed… But it means that you have both kernels installed. Did you upgrade from the betas or RC to 11.0? Otherwise, don’t worry about it. Won’t impact your system. You can install the one you don’t need, but don’t do that until you determine with kernel you’re using (-pae or -default).
