Sorry ! I don't spend much time on Usenet unless necessary, so I'm used
to sending also answers via email. Been a bad Useneter :-( , won't do it
again ;-)

IDL will always let you set device, direct=24. It does not mean the
visual is available, until you really use it (use device,/help to test
that).

As for Accelerated X, I do not have any experience. If the available
mode for Accelerated X is Directcolor, 24 bit, it is very strange, since
this is the default mode for IDL. What are the modes proposed by
xdpyinfo ? It may be that the DirectColor mode proposed in AcceleratedX
is not 24 bit (?), so that IDL reverts to TrueColor ??
Depending on what xdpyinfo gives, you could use a PseudoColor mode, and
still be able to have a private color map.
