Color problems with Linux [message #15091]

Greetings

One of my co-workers is having problems with IDL 5.2
under Red Hat Linux.

After placing the following lines in her .Xdefaults file

idl.gr_visual: PseudoColor
idl.gr_depth: 8

IDL starts up believing that it has 256 colors. The
problem is that the color table as displayed on the
screen contains a fixed random assortment of entries
(at least a hundred, it's hard to tell). Using LOADCT
or XLOADCT does change the values obtained with
TVLCT,r,g,b,/GET, but nothing changes on the screen.

As a result, image display is basically useless. This
is a significant problem for an astronomer who would
like to display images...

Any hints or suggestions would be most welcome.
