Comment 54 for bug 1765363

Hi Ryan, my solution uses bbswitch to turn off the card, which is what Ubuntu used before 18.04. If it works for your hardware in 16.04 (up to and including 17.10) it will work in 18.04. Also if it was working and then stopped working, it must be something you did.

If you'd like support with it, please post an issue on the github repo. Note that the readme has debugging steps. It doesn't actually do very much, so there is not much than can go wrong.
