This is the expected (and documented) behavior: http://rpmfusion.org/Package/xorg-x11-drv-nvidia#head-ba705670506fd0e4b957d 0609fb0c2839dbf2563 nvidia-config-display will only temporarily disable the driver, to permanently disable you need to set livna-config-display's "active" state to "off". I know it's not the best behavior form a user friendlyness perspective, but it's the only option as otherwise, this situation will become pretty common: 1. User runs "yum update" and grabs the latest kernel without kmod 2. User shuts down for the night 3. User powers up next morning 4. Kmod doesn't exist for new kernel, "nvidia-config-display disable" called 5. Drivers are never re-enabled By having the nvidia service call "nvidia-config-display enable" by default and "nvidia-config-display disable" when a kmod is missing, we can have the nvidia driver automatically disable itself when a kmod is missing and then re-enable itself for the user when the appropriate kmod is installed.
