xstdcmap is supposed to define the standard colormap properties
such as XA_RGB_GRAY_MAP.  If you have run it, and the property still isn't
defined, then xstdcmap may be broken.  It also could be that your server
does not expose a gray-scale visual, so xstdcmap does not try to define this
property.  xstdcmap also fails on my system, and I haven't delved in yet to
figure out why.

You can use xprop to help you
make sure the property isn't there (or is).
