Welll duh... That was indeed the "problem", except that they were in the
.Xresources file :-)

Do you have any resource settings for IDL in your $HOME/.Xdefaults file?
If so, I would remove them.
That said, the fact that it prints a resaonable display depth makes me
think that everything is probably okay (apart from the warning message).
On a related note, if you have not doen so already, you should apply the
patch described at

And that produces...
Warning: Cannot find Visual of class PseudoColor for display :0.0
Display depth: 24
Color table size: 256

Try this in your startup file:
if !version.os_family eq 'unix' then device, true_color=24
window, /free, /pixmap, colors=-10
wdelete, !d.window
device, decomposed=0, retain=2, set_character_size=[10, 12]
device, get_visual_depth=depth
print, 'Display depth: ', depth
print, 'Color table size: ', !d.table_size

Liam.
