I've got a Hyper-V on a WINDOWS 10 Surface and I'm using Ubuntu 15.04 as a guest OS. I've successfully resized the Ubuntu screen in a Hyper-V with Windows 8 and 14.04 using the recommendations found in these forums. In the current case however I've had no luck resizing. With the huge pixel count on the Surface 4 it make the guest Ubuntu a real pain in the ass to use.
I'd welcome any suggestions.
