Dear Asti,
we don't have the problems with our linux systems you described.

May be it's a configuration problem of your startup routine.

Our garphic cards all in 16bit mode.

The following lines are from a more general startup file for different
platforms.
( http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl .all)

if strlowcase(!version.os) eq 'linux' then device,
get_visual_depth=depth
if strlowcase(!version.os) eq 'linux' then device, true_color=depth
if strlowcase(!version.os) eq 'linux' then window, /free, /pixmap,
colors=-10
if strlowcase(!version.os) eq 'linux' then wdelete, !d.window
if strlowcase(!version.os) eq 'linux' then device, decomposed=0,
retain=2

..

Hope this helps

Reimar
