I accidentally modified the xorg.conf file. Can I just delete it or I am toasted?

I don't have a copy - blaming on the vi. I was just trying to look at it.

What distro? You might be able to use the package manager to reinstall a base xorg.conf or do a full reconfigure.

How extensively was it modified?

CentOS 5.0

It's screwed up totally. How do I do a reconfigure? I haven't shut down the system yet.

Looks like this:

You can just run "system-config-display --reconfig" as root and it should create a new working xorg.conf for you.
