I downloaded Sindi's netpbm package and followed your directions,
including starting X this time with -swaprgb. (After trying it
first without it.) It's the best result so far, but still a long
way from looking 'real'.
There's much better color, but washed out, and the whole image is
crosshatched. Like there was a window screen between it and me.
Looks pretty good from 20' away....
Now my xterms have a blue title bar instead of a red one.
Thanks to Sindi for that package and the good docs for it.
