Hello, You can try to add a test after this line: https://github.com/eduble/gl/blob/94485a1c9f3eb4f62e5a21a018c814b4232b6b0a/libegl/devices/generic.py#L51 Something like that:

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