Mike,
Make sure the graphics driver is up to date. I know you mention you
have no problems running from the UI, but please try anyway.
If that is not the solution, then there seems to be a mismatch between
your head and headless environment. Somehow the display settings for
headless mode are not correct. Make sure you have the GLX module
installed for your X server.
Best,

We have just recently installed IDV 3.1u1 for Linux and have been able to
get everything to work except for generating PNG graphics when running IDV
from the command line. I am trying to open a simple bundle and generate a
basic output graphic using an ISL file:
runIDV -islfile scripts/MUtest2.isl
We have been able to successfully run a very similar .isl file that creates
a PNG file when ISL is launched with the GUIs. (run IDV, create a simple
plot on the default loaded map, then Open menu > ISL file)
We are stumped as to why we can create a PNG running the software through
the GUI, but get this OFF_SCREEN error when run through the command line
with the -islfile argument.
here is the error:
[root@ddc-ls-eddy IDV_3.1u1]# ./runIDV -islfile scripts/MUtest2.isl
Java 3D WARNING : reported GLX version = 1.2
GLX version 1.3 or higher is required
The reported version number may be incorrect. There is a known
ATI driver bug in glXQueryVersion that incorrectly reports the GLX
version as 1.2 when it really is 1.3, so Java 3D will attempt to
run anyway.
JAVA 3D: OpenGL 1.2 detected; will run with reduced functionality

Thanks for the help,
