I was going to do this video with Kali Linux but the dual screens on the Zephyrus Duo don’t scale properly as Kali will not allow you to enable Fractional Scaling. Which basically means the 1080p display is at 100%, the 4K display is locked to the same scaling so it doesn’t line up 1:1 top to bottom while dragging windows.
I show Fractional Scaling in Pop_OS! 20.10 in this video and how it works properly. Once this issue is fixed on Kali, I’ll be switching back.
sudo apt update && sudo apt install refind
