I bet none of it is video-card RAM; a significant (not necessarily
majority, but significant) portion of the RAM `used by X', though,
is shared libraries that are also used by other processes--and those
are basically `gratis' since you'd be using them regardless.

You need to pick over it with something like memstat; on my laptop,
for example, the top allocations associated with an Xorg process
(hosting an xterm) are, as per mstat:

       9404k: PID  6649 (/usr/bin/Xorg)
       4401k: /usr/lib/dri/i915_dri.so 6649
       3364k: /lib/libc-2.7.so 1 1226 2874 2892 2930 3297 3312 3331 3347 3365 3366 3402 3511 3544 3550 3947 3970 4031 4054 4056 4112 4226 4243 4260 4261 4318 4320 4321 4344 4374 4376 4388 4402 4547 4560 4595 4621 4804 4805 4806 4807 4808 4955 5144 5151 5243 6561 6598 6648 6649 6655 6656 6683

The leading number is the amount of memory allocated privately by that item,
and the trailing numbers after shared libraries are the PIDs of all
of the processes using the shlib.

Also, bear in mind that much of the memory-allocations associated
with *X client* applications are inside the X server process....
