That's correct. If you use the nVidia-provided installer, then you'll
have to reinstall the nVidia driver after each kernel update, as the
driver is only built for the current kernel. You can avoid that, by
using the packages from rpmfusion.org, which update the driver with your
normal yum updates.
For CentOS I recommend the nVidia drivers from elrepo.org.

This sounds like it might be similar to the problem I sometimes find
when updating our 64 bit Redhat 5.6 machines:
When the kernel is updated, e.g. with yum, it seems necessary when
rebooting the machine and running the new kernel, to reinstall the
NVIDIA drivers. Most importantly, make sure that the 32bit compatibility
libraries are installed again. This seems to be necessary regardless of
which coot/pymol binary (32 or 64 bit) that I try to run.
These libraries seem to get missed when installing for a kernel which is
not currently running (using the NVIDIA installer -K option [or is it
the -k option; I can't check at home]), alternatively I've missed to
option to force the libraries to get updated as well as the drivers.
If reinstalling the NVIDIA package isn't immediately possible, just boot
up with the old kernel and all should be fine.
Quoting David Schuller <[email protected]>:
I'll look into this more on Monday. I should have mentioned that the
workstation in question had the proprietary nVidia graphics driver,
and that pyMol and Coot worked just fine before someone updated the
system software with yum.
thanks,

A friend updated software on his Fedora 14 workstation within the
last couple days, and now Coot and pyMol both fail to work. Coot
complains that it can find neither the double-buffered visual nor a
single-buffered visual. Has anyone else encountered this (yet)? Which
packages are the most likely suspects?
I'm using both on fedora 15 without problems. Your error message
suggests an issue with opengl - are the appropriate drivers/modules
available? "glxinfo | grep render" should say something like:
direct rendering: Yes
OpenGL renderer string: GeForce GTS 450/PCI/SSE2
