You were both correct I was in unity-2d, I knew I forgot to do something while setting up the new box to test this heh.

Though I suppose it's good to know that this only works for unity not unity-2d so my mistake wasn't all in vain.

Anyways, it did work and I've now installed it on my main Ubuntu computer and worked fine there as well. Thank you very much for this, I was immensely disappointed to lose this feature.
