Hello all,
I am facing the following problem:
I've installed the last Gephi release (Gephi 0.8.2-beta) for linux, which is an interactive visualization and exploration platform for all kinds of networks and complex systems, dynamic and hierarchical graphs (
http://http://gephi.org/).
The Gephi documentation specifies that OpenJDK is not supported, Sun JDK is required. In addition, OPENGL is required.
My system is the following:
Distribution: Fedora 19 (i686) (32 bits)
Cinnamon 1.9.2
Kernel: 3-11-3_201.fc19.i686.PAE/# 1
Laptop: HP Pavillon dv6000
Processor: Intel Core 2 CPU T5500 1.66 GH
Memory: 2 GB
Graphic card: NVIDIA G72M GeForce Go 7400
My laptop is on dual boot Windows Vista Home on which I have no problem with Gephi. It's only under Fedora 19 Linux distribution that I have a problem.
On Fedora, I hope I have correctly installed java as shown here:
[rene@localhost bin]$ alternatives --config java
Il existe 3 programmes qui fournissent « java ».
Sélection Commande
-----------------------------------------------
* 1 /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.60-2.4.2.7.fc19.i386/jre/bin/java
2 /usr/java/jdk1.7.0_40/jre/bin/java
+ 3 /usr/java/jdk1.7.0_45/jre/bin/java
I use the two following commands to run Gephi:
cd /gephi/bin
LIBGL_DEBUG=verbose ./gephi &
I get the following log:

In this forum, I found a thread very closed to my problem: "Getting 3D Acceleration working on Intel 82865G, no xorg.conf" (03-09-10, 03:46 AM)
I followed this thread without succeeding to fix my problem:

Could someone help me in solving this problem?
Many thanks in advance for your attention and your help.
