Could it be that you are accessing the machine where you try to start OpenCOVER remotely via SSH and your `DISPLAY` is set accordingly? This would explain why `xterm` works.\r\n\r\nFor efficient OpenGL rendering you should start OpenCOVER on the machine where you have your display device connected. But you also have to configure the X server on that machine such that OpenCOVER is allowed to access it. If you share the machine only with trusted users, something like `xhost +LOCAL:` directly after the X server has been started, should help. Where you have to put such a command depends on your display manager (XDM, KDM, LightDM, ...)."}}
