[Gate-users] Debian and OpenGL

[Ray Raylman]

Hi-

We have installed GEANT4 on a Debian system.  When we perfom one of the
initial testing sequences for GEANT4 we get the following error:

*************************************************
Idle> /vis/open OGLIX
G4OpenGLViewer::G4OpenGLViewer couldn't open display.
G4OpenGLImmediateX::CreateViewer: error flagged by
negative view id in G4OpenGLImmediateXViewer creation.
Destroying view and returning null pointer.
ERROR in G4VisManager::CreateViewer during
OpenGLImmediateX viewer creation.
 No action taken.
WARNING: No viewer created.
*************************************************

Doe anybody have a suggestion on what the problem is?

Thanks, Ray
