![]() To build the apps, I used the default compiler, X11, OpenGL and Qt of lxplus. QGLTempContext: Unable to create GL context.Īnd if I kill XQuartz, and restart the apps, they display properly.

The Geant4 output looks correct in both cases. I see this issue when connecting to lxplus from my local mac machine (OSX 10.15.7), but not when connecting to lxplus from another linux machine (Debian 10.9 for that matters), so this is probably not an issue with the installation, but rather with the display forwarding on mac and/or with XQuartz (I am using the most up-to-date version: 2.8.1). ![]() I can successfully compile and run the basic examples interactively ( >$ examples/basic/B1/exampleB1), the interactive window pops up and everything looks good except for the empty viewer-0. I am working remotely on lxplus and use the software from CVMFS. I am new to Geant4 and I am trying to run the first examples given in the documentation. ![]()
