Gephi has no graph window in Redhat Linux

[Rodger22]

Dear Experts,

Previously, I was test driving gephi on Windows.
I looked at the sample Power Grid in many different outputs.
That part worked fine.

But then the NEO4J plugin did not work on Windows 7.

---

So, I got another disk, and installed Redhat Linux 6.4 on it.

uname -a
Linux black.testrac.com 2.6.32-358.11.1.el6.x86_64 #1 SMP Tue Jun 11 10:24:58 PDT 2013 x86_64 x86_64 x86_64 GNU/Linux

lsb_release
LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch

Then installed: gephi-0.8.2-beta.tar.gz

----

Gephi starts fine.

But now, on Redhat, the graph software, gephi, has no graph window!!!!


---

On Redhat, I go

Menu
Window
Graph

But there is nothing!



What platform is gephi designed to run on?
I suspect that it is Apple/Mac. Is this true?


Is it possible to use Gephi on Redhat?
If so, how?


Thanks a lot!

Hello Everyone,

Here is an update:


On Redhat 6.4:

I can't remember where I found this tidbit, but it was relevant.

cd /gephi/gephi/bin

LIBGL_DEBUG=verbose ./gephi &


Loading native libraries
libGL: OpenDriver: trying /usr/lib64/dri/nouveau_dri.so
libGL error: dlopen /usr/lib64/dri/nouveau_dri.so failed (/usr/lib64/dri/nouveau_dri.so: cannot open shared object file: No such file or directory)

In the meantime I also did some more install trial and error.

I installed Suse on spare disk. Then installed gephi.

I couldn't get gephi to run as a regular user.
There was always an issue with the display, no matter what it was set to.

No protocol specified
Error: Can't connect to X11 window server using ':0' as the value of the DISPLAY variable.
See the /home/oracle/.gephi/0.8.2/dev/var/log/messages.log for details.


However, gephi did run as root.
It showed the graph window, the controls,
and the examples as they look in windows.


Go figure.

BTW, I'm using the video card:
NVIDIA Quadro FX580

Seems like this is another one of those Linux issues where it has
nothing to do with the software. But with fundamental issues
with the underlying platform. Like, video displays



So everybody, any ideas?

What is the secret to getting gephi to work with Redhat?

[Rodger22]

After a lot of investigation, I figured it out.

Hope it's useful.
