How about tearing apart the startx?
In startx, there is some argument will be checked, like client argument,
server argument ...etc.
I don’t what module you want to debug and I guess maybe you can find out
where is the right position in startx or some other script file called by
startx which activates the module you want to debug.
If you find out where it is, mark the name and awake it after using gdb to
attach the debug-version Xserver.
Hope it will help you,

Thanks, I know startx is a script file.
My step is: 1) startx in the console
2) when FC4 enter into the x windows and
then in the other
PC use ssh to login
3) gdb /usr/X11/bin/X $(/sbin/pidof X)
From the steps, i didn't know how to postpone activating other modules
after awaking the Xserver, because i use startx script to load all modules
at one time;
Also many thanks
