NVidia
NOTE: With default install of Fedora Core 14 I could play Minecraft after switching to Nvidia proprietary driver.
Install Nvidia proprietary driver
Download Latest Driver
Download latest Nvidia driver from http://www.nvidia.com/
Disable nouveau
Boot to command line. One way to do this is to add an argument at Grub boot loader. At Grub boot menu select current kernel and press 'a' to enter kernel arguments. Add a 3 to end of line and press ENTER.
This should boot to command line. Now disable nouveau by logging into system & as root edit /etc/grub.conf by adding rdblacklist=nouveau to end of your latest kernel. Save and exit file.
# vi /etc/grub.conf
Create a new file in /etc/modprobe.d/ called disable-nouveau.conf:
# vi /etc/modprobe.d/disable-nouveau.conf
Add these two lines to your disable-nouveau.conf file then save & exit:
blacklist nouveau options nouveau modeset=0
Prerequisite software
Run these commands to verify if you have minimum prerequisite software installed:
size --version make --version insmod --version Xorg --version gcc --version ls /lib/libc.so.6
The default Fedora 14 install I used did not include several of the required packages. I installed gcc & kernel-devel which resolved the other dependencies.
# yum install gcc.x86_64 kernel-devel.x86_64
Reboot
Now reboot system so you unload the nouveau drivers.
# reboot
Enter the boot menu again just like above & add an argument of 3 to end of current kernel line (should be after rdblacklist=nouveau you added above).
Install driver
Log into system and become root. Enter the directory where you downloaded the current Nvidia driver and type:
# sh ./NVidia*
Follow on screen prompts then reboot like normal.
