Sorry I should have explained. A VT1000 is a {personal opinions on} slow,
crappy,[personal opinions off} 1 bit per pixel X terminal. With 2MB memory.
It can display a few xterms and stuiff, but for real graphical apps it is a
non starter. However it certainly is an X server, of sorts. However it has
no display postscript and certainly no PEX.  So either

a)  xdpyinfo is in error and asking the wrong questions, or
b)  the server is in error and giving the wrong answers.

I tend to favour the latter theory.  Why have DEC made their servers behave
like this? After all DEC wrote X11 (ref: Schlieffer et al, X Window System,
introduction) How is an application supposed to determine the capabilities
of the server??
