Hi Stuart, Java3D 1.3 (compatibility mode) only was an option when installing IDV on a 32-bit headless CentOS server. When I tried installing IDV on a 64-bit headless CentOS with the exact same internal card (Embedded ATI ES1000 with 16MB memory), there wasn't an option for Java3D 1.3 (compatibility mode) and subsequently IDV won't run. Unfortunately, the embedded ES1000 is standard on a number of Dell PowerEdge servers. There are no known drivers which support GLX version 1.3+, at least that I could find. Evan -----Original Message----- From: Stuart Wier [mailto:wier@xxxxxxxxxx] Sent: Friday, December 04, 2009 1:27 PM To: idvusers@xxxxxxxxxxxxxxxx; elowery@xxxxxxxxxxxx Subject: Creating ISL script / xidv bundle -- "OFF_SCREEN_BUFFER_ERROR: Renderer: Error creating Canvas3D off-screen" The reply below from Evan Lowery indicates his solution to a similar problem which I have on running the IDV with an isl file on a headless Solaris ix6 system. He says the solution was "specifying Java3D 1.3 (compatibility mode) during install instead of the default Java3D 1.5." How to do this is not given (installing what - IDV?). Please tell me how to "specify Java3D 1.3 (compatibility mode) during install instead of the default Java3D 1.5." my error message is: runIDV -Dj3d.usePbuffer=false working_plan_view.isl Fri Dec 04 08:46:30 PST 2009: Loading bundle: ./idv_config_files/working_plan_view.xidv 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.

I have Xvfb running on my system, a matching $DISPLAY is set, and the error for no vfb does not appear. Stuart Wier * From: "Evan Lowery" <elowery@xxxxxxxxxxxx> * Date: Mon, 8 Jun 2009 07:41:52 -0400 All, Thanks for your help with this issue. I was finally able to get IDV 2.7b2 running on a 32 bit CentOS server by specifying Java3D 1.3 (compatibility mode) during install instead of the default Java3D 1.5, and using Xvfb when running ISL scripts. The error below no longer occurs and all ISL scripts run as they should.
