Re: [idvusers] Error generating graphic from command line


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.

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.
