Is this a remote glx client? VTK requires OpenGL 3.2, which isn’t possible with remote glx.


Thanks a lot. Do you know if I am able to use opengl 3.2 on a server?

Yes, you can use OpenGL 3.2 on a server if you do off-screen rendering. Can you describe in more detail what you are trying to do?


I am using x2go to log in our linux server to build a c++ project. Our server has a Nvidia Quad graphics card.

Right now I am just trying to run the rendering test that consists in rendering a cone.

The initial project I am going to use itk to open a segmentation file and vtk to convert it to a polygon mesh.

I can’t install the opengL drivers. I have to ask the technichian to install them.

Anything more specific?

I’ve never used x2go. Is it documented anywhere that it supports OpenGL 3.2? Most remote viewing methods only support OpenGL 1.x, if they support OpenGL at all.

Installing OpenGL drivers will probably not fix the situation. You need to verify that x2go will work with OpenGL 3.2.
