Thank all of you for your helpful advice. What I did was essentially what you all suggested. I have my 32 bit production machine that uses the same 340.XX driver. I opened a terminal on that machine and did: [mlapier at mushroom ~]$ rpm -qa | grep nvid nvidia-detect-346.35-1.el6.elrepo.i686 kmod-nvidia-304xx-304.125-1.el6.elrepo.i686 nvidia-x11-drv-304xx-304.125-1.el6.elrepo.i686 [mlapier at mushroom ~]$ That gave me the list of packages that live on that machine. I went to /var/log/yum.log on the 64 bit machine to see what had been installed. I ripped it out by the roots and then installed the same 64 bit packages that live on my 32 bit machine. yum install nvidia-detect, kmod-nvidia-304xx, nvidia-x11-drv-304xx Now yum update finds no nvidia packages to install, and it will stay that way. All better Again, thank you all for your willingness to help and for your on target suggestions.
