I have a color vaxII/gpx running ultrix 3.0 (field test 2) and the 
x server only supports a visual of depth 8. In addtion, the default
pixels for black and white are not 0 and 1 as I expected. When I draw
lines using GXxor they don't appear at all. I have set the plane mask
of the gc for the operation to 1 but this doesn't help. I'm not quite
up to speed with creating other colormaps (e.g. a colormap with only
two entries for the foreground and background colors) but this might
be necessary. When I run my application on a black & white sun3 everything
works fine. 

If you know how to fix this problem I would really like to hear from you.

Thanks,
