That's correct - you shouldn't have to modify anything - the package 
should take care of everything for you. With one caveat - the package 
was designed against a clean system and there is no way we can account 
for every possibility so it is possible that some users may have 
modified their systems in such a way that we had not envisaged or 
accounted for. This has happened, and with feedback from users we have 
been able to continually improve the packages to account for some of 
these situations.

To give you an idea what the package does; first any existing xorg.conf 
is backed up and removed and then a clean xorg.conf is freshly created 
with the necessary "Files" section including the correct path to the 
nvidia libs. The driver is then enabled and (on el6) the necessary steps 
are taken to disable the nouveau driver. This should give all users a 
basic working installation and subsequent updates should not break this.

Some of this has evolved over time and all might not have been in place 
when you first installed the driver if you've been using the packages 
since the initial release of 6.0 - it's been a process of ongoing 
development.

But the intention is always for the packages to operate in a seamless 
fashion - install, update, forget; other than any special user-specific 
configurations you may need to make to support things such as multiple 
displays etc. If the packages aren't operating as designed then please 
file a bug and we will investigate and fix any issues. WRT the bug 
above, I was unable to replicate the issue and it was my understanding 
the issue was caused by not rebooting after updating the drivers.

So to clarify, on a fresh install of EL6, installing the correct nvidia 
drivers for your device from elrepo followed by a reboot should leave 
you with a fully working system.
