Hello,
You can try to add a test after this line:

gl/libegl/devices/generic.py

Line 51 in 94485a1

devstr = egl.eglQueryDeviceStringEXT(self.egl_dev, EGL_DRM_DEVICE_FILE_EXT)

Something like that:

    devstr = egl.eglQueryDeviceStringEXT(self.egl_dev, EGL_DRM_DEVICE_FILE_EXT) 
    if devstr is None:
        return "EGL device unknown"
