/usr/bin/X isn't the binary of the X server itself but of the Xwrapper.
Generally, there's a couple of gotchas when starting the X server from
gdb, so I usually attach to the X server after startup with something
like

sudo gdb -p $(pidof X)

It'll hopefully be easy to reproduce with gdb attached then. :)
