[X2Go-User] High performance OpenGL issues

This is normal since there is no proper GL support in X2Go (through lib-nx) by now.
This is a work in progress from the Arctica team by now but not completed yet.

Objet: [X2Go-User] High performance OpenGL issues 



Hello, 

I am trying to have high-performance OpenGL graphics in X2go, from a modeling software : it is based on Jogl; for instance, you can rotate objects in the GUI. I am having issues. 

I am using : 
- X2go client 4.0.5.1 on Windows 7 
- X2go server v 4.0.1 on RHEL 6 with KDE 

When I start the software on a physical machine with RHEL 6 and an updated NVIdia driver, on the physical screen, it works perfectly. 
When I start the software on the physical machine but with the display in the X2go client, the software crashes almost immediately 
Strangely, when I start the software on a virtual machine running RHEL 6 inside Vsphere, with the display either in the console or X2go, it works perfectly. 

So I assume that it may be related to other libraries brought in by the driver. 
I already figured out that I can work around the libGL.so from NVidia, if I add to the environment : 

export LD_LIBRARY_PATH=/usr/lib64 

In this way, the software uses the system's libGL.so, I can see it with ldd /usr/bin/glxinfo 

Unfortunately, this is not sufficient. Does anybody have a solution ? or a hint ? 

Best regards 

R. Grasso
