This is a Vib Image to get the required linux-surface patches working on Vanilla OS, it's based off of the nvidia-exp Vib Image from Vanilla OS. The default nvidia Vib Image does not want to build with the latest linux-surface kernel.
Surprisingly simple, open the terminal and run abroot config-editor a file should open in nano (or any other text editor you have configured).
In the file change the name parameter to sakloui/surface-nv, then save and close.
Then run abroot upgrade and wait for it to finish and reboot. you can check if it's working by opening the terminal and running uname -a, if the surface kernel is shown then it should be working.
I currently haven't made a Vib Image for this, but you can create a template from here follow their steps, and copy most of the config from this repo.
