I'm trying to get Vulkan running on my linux laptop. I've tried this:
https://launchpad.net/~canonical-x/+archive/ubuntu/vulkan
from here: https://01.org/linuxgraphics/blogs/jekstrand/2016/open-source-vulkan-drivers-intel-hardware
But the packages have been purged from the PPA. How can I get Intel Vulkan drivers for Ubuntu 16.04?
