As the nouveau driver for nvidia cards (installed by default with FC13) does not adequately support dual monitors I would like to replace it with a nvidia driver. I'm using this documentation: http://rpmfusion.org/Howto/nVidia http://www.mjmwired.net/resources/mjm-fedora-nvidia.html Here's the procedure I've decided to follow, although I still have some questions, mostly based on discrepancies between the two sets of instructions: 1. determine card model and level of support [98] ~ $ /sbin/lspci -nn | grep 'VGA\|NV' 06:01.0 VGA compatible controller [0300]: nVidia Corporation NV44A [GeForce 6200] [10de:0221] (rev a1) I found the card name and PCI ID (221) listed at http://www.nvidia.com/object/IO_18897.html: GeForce 6200 0x0221 So apparently this card (GPU) is supported. 2. modify grub.conf to disable nouveau driver Both instructions say to add this to the end of the entry for the active kernel: rdblacklist=nouveau ...but the rpmfusion.org/Howto/nVidia instructions differ in saying to add instead: rdblacklist=nouveau nomodeset QUESTION: Google tells me that specifying "nomodeset" basically tells the system to use an older set of software/drivers which does work but may be slower or have some other issues that people would like to eliminate. Is the "nomodeset" parameter necessary in this case? The rpmfusion.org/Howto/nVidia instructions also say that SElinux protection should be lowered: setsebool -P allow_execstack on QUESTION: Is this really necessary? Does it risk compromising the security of my system? 3. Select and install proper kmod (Fedora Kernel Module) which matches the driver. This kmod must match the specific driver for the PCI ID determined earlier. As far as I can tell from www.mjmwired.net/resources/mjm-fedora-nvidia.html (and since my system has been using PAE kernels) the proper kernel module to use is: kmod-nvidia-PAE ...which I can install using yum (as I already have the rpmfusion repository configuration files): su -c 'yum install kmod-nvidia-PAE' ...and then reboot. MOST IMPORTANT QUESTION: Suppose this doesn't work and the reboot hangs (presumably with the X startup). Will I be able to use a previous kernel (on the grub menu) or will yum have automatically associated kmod-nvidia-PAE with all the retained kernels? Or is the back-out procedure (from run level 3) to (1) yum remove kmod-nvidia-PAE (2) take out the extra parameters on the kernel line in grub.conf, and (3) reboot? Thanks for the help!
