ssh in from another system to avoid using the screen. Also you will need 
to use
some command line options to make using gdb usable start the Xserver 
with these

    -keeptty -dumbSched

-keeptty allows you to ^C to get into gdb at anytime
-dumpSched stops the smart scheduler interrupting each time you step
