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
two  options:

    -keeptty -dumbSched

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