Yes, I am. ".Xdefaults" can control the visual class. But if I start
with a class, I cannot change to another.

[zhang@dao:~/IDL]$ idl
IDL Version 5.5a (linux x86). (c) 2001, Research Systems, Inc.

IDL> device,get_visual_name=temp & print, temp
DirectColor
IDL> DEVICE, TRUE_COLOR=24
IDL> window
IDL> device,get_visual_name=temp & print, temp
DirectColor
IDL> exit
[zhang@dao:~/IDL]$ (change .Xdefaults)
[zhang@dao:~/IDL]$ idl
IDL> device, get_visual_name=temp & print, temp
TrueColor
IDL> device, Direct_Color=24
IDL> device, get_visual_name=temp & print, temp
TrueColor
