[comp.windows.x] X on Convex

I am interested in implementing X on a CONVEX machine.
If anyone out there has any past experiences, advice, information,
horror stories,etc., I would appreciate hearing from you. Thanks in
advance.

P.S. To all those individuals who replied to my earlier question on the
     SUN 3/260-280 , thanks again.

We are Convex installation #6 (1985).  All versions of X since V9R4 have
compiled and run fine on the Convex.  Convex supports X11 for a small fee as
a product called CX.  We did find that the Convex ethernet packet size is
smaller than that in X and undetectected by X.  There are three solutions:
(1) Don't flush X data larger than 8K bytes at time.  (2) Recompile the Convex
UNIX kernal for a larger packet.  Convex TAC will do this for you.  (3) Recompile
X for a smaller packet.  (I don't off-hand remember the names of the Convex
system variable or X variable for the packete size.)
