I was hoping someone with specific FC (or MythDora) knowledge would help
out (since I know nothing of either), but since they haven't, yet, I'll
mention that the "normal" approach for starting X is to run a script
startx (often /usr/bin/startx), which will then execute a program called
xinit (which may be /usr/bin/xinit, if on a recent X.org, but may be
buried in a /usr/X11R6 subdirectory on some systems). Often the call to
xinit includes arguments for the server (sometimes hard-coded in the
script/program that calls xinit, sometimes provided through command-line
arguments or environment variables).
If you're using gdm or another display manager, though, there may be
more to worry about in addition.
So, you may need to widen your search a bit, too.
