Your font problem occurs because either your font path is incorrectly set
up and/or you are missing some fonts. I suspect the later because HP failed
to supplied some standard MIT fonts including all "lucida", "olcursor",
"olgl10", "olgl12", "olgl14", and "olgl19". The lucida fonts are normally
found in  75dpi and/or 100dpi whereas olg* are normally located in misc.

First check to see if these fonts are listed in "/usr/lib/X11/fonts/misc" and
"/usr/lib/X11/fonts/*/75dpi[100dpi]". If they aren't there, you have to obtain
the standard MIT bdf fonts. Check FAQ Subject 45 for MIT software and FAQ
Subject 32 for some "scf" font info.

If they are there, then it is probably your path.  To check the font path
currently being used by your HP server, type xset -q. Make sure that "misc"
and either "75dpi" and/or "100dpi" are listed in the Font Path. Look at FAQ
Subject 31.

Our problem here is not with HP but rather with DEC.  When running XView
applications (based on X11R4) and displaying them on a Dec (running X11R3),
I had to first add the above fonts but after that, the following error has
occurred:

    XView warning: xv_rop: can't handle drawables of different depth
    XView warning: xv_rop: xv_rop_internal failed
    X Error:  BadAtom
      Request Major code 17 ()
      Request Minor code 0
      ResourceID 0x7f0000
      Error Serial #383
      Current Serial #383

The application actually displays, but once an event occurs, it crashes with
the above message.

I posted this on the net but have not received any replies yet.

Good Luck.
