Been there.  Several times.

Hopefully, you made a backup copy of the xorg.conf file before you
made changes.  If so, then you simply need to copy your backup version
over top of the new.

You don't specify which distro you are using.  Most newbies use Fedora
(thanks to Jarrod's great instructions) or KnoppMyth.  Since I am
using Fedora, I'll give you instructions for it. (I'm not home, so I
am working from memory here, please forgive me if my memory fails me.)

1. Boot your system.
2. After it appears to have fully booted.  Press ALT-F1.
   (This will get you into a character-based terminal session.  )
3. Login and then become superuser.
4. cd /etc/X11
5.cp xorg.conf.bak xorg.conf
   (substitutute the filename you used for your backup file)
6. init 3 && init 5
   (this will force X to restart)

Hope this helps.
