Now that I got my new system running Fedora 13, I needed to configure my Nvidia card to support my two monitors.
It was pretty straightforward, and I found a post that does an excellent job of summarizing it at http://fedorasolved.org/video-solutions/nvidia-yum-kmod
I will comment on one thing though – when I did the install, I used the basic kernel for my i686 32-bit CPU. I found that my 4 GB of RAM only showed up in the system information page as 2.7 GB! I looked into this a bit, and it turns out that if you want greater than 3GB of memory supported, you need to have a 64-bit machine, OR you can handle this in software with the PAE kernel.
PAE stands for “Physical Address Extension” and all you have to do in install the PAE kernel, and then also the PAE Nvidia modules, and everything will work fine!
I know have my machine up with 8GB of RAM and working perfect! I read that the PAE kernel will cause a performance hit (sort of like doing RAID via software versus hardware I suppose), but I don’t see anything like that on my system.
