Thanks for posting those instructions and I might try later but for now I'm just dropping back down to 5.8.X when I'm using DisplayLink as I'm worried, (as per some on that original thread) that this 5.9 patch will break 5.8.X
5.9 seems stable and I haven't hit any issues so far but haven't got hours to debug at the moment so might just stick on 5.8 until things are a bit more complete.
