If you use an Nvidia card in your system and install Fedora 12, Fedora will use the Nouveau driver by default. Follow these steps to disable the Nouveau driver and install the Nvidia proprietary driver.
-Download the latest Nvidia driver from their web site
-Drop to init 3 (CTRL + ALT + F2, login as root, run "init 3")
-Install the driver using:
./NVIDIA-Linux-x86_64-190.42-pkg2.run -k $(uname -r)
Here is a list of VGA modes. Replace 31B with the desired mode:-I also removed the nouveau x11 package, but it isn't necessary
1600x1200 - 346
1280x1024 - 31B
1400x1050 - 348
1024x768 - 318
800x600 - 315
rpm -e xorg-x11-drv-nouveau --nodeps
