The basic examples hang, when started in interactive mode, after typing /run/beamOn 10
and the tracks are not drawn. but when i desable vizuallization by commenting " /vis/open OGL 600x600-0+0" in vis.mac file (ie: #/vis/open OGL 600x600-0+0) all works ok.
(I use geant4.10.05 and QT versian 5.9.5 and I install geant4 with these component: GDML=ON MULTITHREADED=ON INSTALL_DATA=ON OPENGL_X11=ON RAYTRACER_X11=ON USE_QT=ON)
Are there other Ubuntu users who see the same problem? How can I fix this?
Thank you.
It’s important to install the graphics driver appropriate to your graphics hardware. We find that the generic driver issued with OSs such as Ubuntu do not always work correctly. You will have to Google your specific system.
Hope that helps.
I think that was the cause of the graphics card driver. I installed Ubuntu 16.04 and the problem was fixed.
That’s good news. Thanks for letting us know.
