By the way, you could do something like the following if you actually
want this from the Linux command line:
~$ idl -quiet -e "exit, status=pref_get('IDL_GR_X_RENDERER')"

0

0 for hardware, 1 for software:
IDL> print, pref_get('IDL_GR_X_RENDERER')
0
Use 'IDL_GR_WIN_RENDERER' on Windows.

See the RETAIN keyword for WINDOWS, WIDGET_DRAWS, etc. I have the same
problem on my Linux machine and I always have to specify software
rendering to make things work properly.
I don't know if my answer is what you are looking for...
