You need to run your XServer in either 8-bit or 24-bit
(what I recommend) mode. Not the 16-bit mode you are
probably in now. :-)
If any of you Linux-types want to write the definitive
answer to this question, I'll make every effort to save it
in a place where I can find it. (I'll even add it to
my web page, so we don't have to answer this question
any more. :-)
Cheers,
David

David,
this is the definitive answer ;-)
Although: I successfully got IDL to plot something on my laptop which
is running 16-bit mode by tricking it to believe it has 24-bit. I have
no idea if this is driver specific (ATI card) or a general XFree4
feature. All I did was to set the default depth in XF86Config to 24.
While the laptop then starts in 16 bit mode, it apparently adds a
24-bit mode to its `xdpyinfo`, and IDL seems to use that information
to determine if it can run. CAUTION: There are some side effects:
While !D.N_Colors reports 247,000 or some other high number,
!D.Table_Size is limited to, in my case even 64(!).
Oh... yes... and don't forget decomposed=0 ...
Cheers,
Martin
