Humm. Seems like that's the startup script we have been
recommending for at least a month now. :-)

Cheers,

David

AHA! Yes that is it! I had decomposed=0 in there, and it locked IDL into
Direct Color, and causing device,true=24 commands to be ignored, and
hence the goofy diret color behaviour.

Now I get normal color. YAY!
Thanks a lot for help!

For any who are interested, here is my startup script:


;startup.pro
;calls my startup procedures for idl

; DISPLAY _________________

; fix the IDL 5.5/Linux colour problem
if strlowcase(!version.os) eq 'linux' then device,true=24
if strlowcase(!version.os) eq 'linux' then window,/pixmap &wdelete ; fix the IDL 5.5/Linux colour problem
if strlowcase(!version.os) eq 'linux' then device,bypass_translation=0
if strlowcase(!version.os) eq 'linux' then device,retain = 2


device,decomposed=0


print,'Startup ran'

This is funny I got colors with your script too, but what is the
difference to my
script

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
if strlowcase(!version.os) eq 'linux' then wdelete, !d.window
if strlowcase(!version.os) eq 'linux' then device,bypass_translation=0
if strlowcase(!version.os) eq 'linux' then device, retain=2
if strlowcase(!version.os) eq 'linux' then decomposed=0
delvar,depth



I have added the line at the correct place and this didn't work!

My result is that it is forbidden to ask for the visual_depth!!!

If I exclude this line and set myself depth to 24 all is good, but how
will I determine now between 16bit and 24 bit ?

Yeah.

In fact I had grabbed a very similar startup script about week
ago, and I think it failed because the order of steps that
I had was wrong (with the decomposed = 0 before true=24 statement,
which seemed to cause the true = 24 statement to be ignored,
(as is described in the IDL help).)

It is nice to finally have come full circle and completed the journey
to whence I started.

Cheers,
bob

PS Let's just say I find it a lot more comfortable in Win2000 (where
I almost know whats going on) than Linux.
