Without more information than this it is awfully hard to guess what is
going on.  Let me try anyway:

1. Most Linux systems out of the box have the Xwindows set up for
16-bit "TrueColor".  I take the view that 16 bits is not, for
scientific purposes, TrueColor.  XAS works either with 8-bit
PseudoColor or 24/32-bit TrueColor.  You need to change the Xwindows
configuration file (carefully) to specify one of those.

2. The command not found suggests that in your logging in you do not
dot LOGIN.SH or source LOGIN.CSH in the $AIPS_ROOT area.  During
installation that is done so the aips command (a symlink in $SYSLOCAL)
was known because the LOGIN files put $SYSLOCAL in your path.  At the
later time this had not been done.
