I would like to display RGB images, with, for instance higher values for
the Red component causing redder colors, and higher values of the blue
component making them bluer. I used to be able to do that pretty easily,
using the

tv,image,/true

However, since I've been moved to a Linux workstation, it doesn't work.
I could provide detailed symptoms if you want, but it's obviously a
configuration problem, so maybe the easiest way is to ask how I need to
configure my IDL session to display these things properly. Attached is a
copy of the xdpyinfo output for my system. What device commands should I
use?
