Hi, Glad that it helps :). I am not sure if the interface actually doesn't work, because it might if the Optimus mode would switch to use the Nvidia card dedicatedly, but since that is not supported by the nouveau driver, it might not happen. Not sure what happened to the Bumblebee projects and the likes and if it would affect this. As long as an existing interface that is selected will always work, it could be omitted indeed.
