Linux port of what?  If you are talking about McIDAS, then I am amazed
and disappointed that the work that we did on this is being ignored.

>He cannot get an 8 bit pseudo-color visual.  Do you know the magic?

One can, as root, run Xconfigurator and specify the set of visuals that are
wanted and which will be the first.  The key is to do this in a text

o while logged on through in a graphical environment, hit CTRL-ALT-F1
  this should give you a full screen text window
o you login as root
o type 'init 3' to go to init level 3 (get out of graphics mode)
o run Xconfigurator and setup up the visuals
o after convinced that the test works as desired type 'init 5' back in
  the text window

The thing about Linux is that McIDAS works pretty well in the 24-bit 
mode.  A chat with either Russ or Chad or both at the Long Beach AMS
meeting seemed to indicate that Rod had been working on areas of the code
that were deficient with regards to McIDAS in 24-bit modes.  I think
that you will find that if you are using GNOME, you will definitely
want to be working in a more-than-one-byte visual environment.  In
a 24-bit mode, one can run other Unix apps like Netscape without
worrying about running out of colors.
