I am the original reporter of this bug. I am working on a fresh install of Ubuntu, a fresh install of java JRE 1.6, and a fresh install of Gephi 0.7a. when I launch Gephi (via ./bin/gephidesktop), no graph window appears. I select the Window:Graph menu option and Gephi throws this exception. I've repeated this after a reboot of Ubuntu.

Hi, do not use OpenJDK but only the official JRE. See http://gephi.org/users/install/#linux

Hi,

I am having the exact same problem here, except that I am not using OpenJDK but the Sun JDK.

$ java -version
java version "1.6.0_15"
Java(TM) SE Runtime Environment (build 1.6.0_15-b03)
Java HotSpot(TM) 64-Bit Server VM (build 14.1-b02, mixed mode)

Running "$ ./bin/gephidesktop" starts gephi but does not show the Graph window. Selecting "Window -> Graph" will result in the same exception as pasted above!

Any ideas? Best
Daniel

That issue is resulting from somthing bad happened during init, I would need the complete log to get the original error source.

Could you locate the message.log file and paste it here ? Thanks

As requested: the messages.log file. Hope this helps...

I've run into the same problem as above.

Please note that I run gephi-0.7-alpha4 on Ubuntu via VirtualBox (Host: Mac OS 10.5.8/ Guest: Ubuntu 10.04). I've to use this computer at work.

Strangely enough, I managed to run gephi-0.7-alpha4 on my home PC (OS: Ubuntu 10.04) without any problems. Unfortunately, I can't use my PC at work.

Btw I also tried gephi-0.6-beta3.linux.i586 and had the same error.

Thanks a lot for your help.

Ari

Hi, this seems to be a graphic-related error.

The original error is "java.lang.IllegalArgumentException: GLDrawableFactory.chooseGraphicsConfiguration() was not used when creating this Component" and it comes from the X11 code that is managing the OpenGL initialization.

So this problem is related to JOGL (our OpenGL) library and your system. I recommend to update your graphic drivers and latest JRE.
