Ok, here’s a bit more on the issues: I see in Xorg.0.log that it appears to have loaded the NVidia drivers I built from proprietary. But, and this may, or may not be significant, the user’s home directory is, of course, NFS mounted.

And his old machine that dies was running CentOS 5.

Is it possible that some of the gnome settings are breaking things with CentOS 7‘s default gnome? If so, what kinds of things should I be looking for?
