your conclusion is likely wrong. it usually are the updates
that mess up the installation, particularly if they update
the X server, since red hat doesn't distribute the binary
only driver from nvidia, only the dri/mesa derived ones.
those two have files that collide. the best chance is
probably to re-install the nvidia driver.
