You can also do kate /etc/X11/xorg.conf if you are not very familiar with commang line and nano. Kate a gui text editor.
On a side note, if you wanna try an "out of the box" distro, try out sabayon linux.. Has drivers, beryl, games, codecs etc everything installed by default. Its much better for people who are trying to "evaluate" linux and find out its strengths and weaknesses.
