Installed nvidia drivers using #yum install kmod-nvidia only to find out a blank screen with blinking cursor on reboot.This problem is due to Nouveau driver taking control of the graphic card at an earlier point in the boot procedure.To fix this problem you should make sure that nvidia proprietary drivers are used rather than nouveau driver provided by default in Fedora 11+.

Follow the steps to fix this problem, before installing nvidia drivers  ::

#vi /etc/modprobe.d/blacklist.conf

and append the following line in the bottom — “blacklist nouveau

now open grub.conf file

#vi /etc/grub.conf

and add this to end of lines starting with word kernel — “nouveau.modeset=0 vga=0x318

now perform

#yum install kmod-nvidia

If you are stuck at blank screen on reboot go for alt+ctrl+f1 and follow the first two steps.
