But since you're using elrepo you have an easy solution provided by these nice folks: they've created a new set of packages that will stay at the 304 level while getting any upstream updates. You should probably do something such as: rpm -e --nodeps nvidia-x11-drv kmod-nvidia yum install nvidia-x11-drv-304xx kmod-nvidia-304xx
