For my own sanity I'm documenting how to enabled
The Vulkan on
The Ubuntu 19.04. I used information form
linuxconfig.org to make
The Vulkan happen.
sudo apt install libvulkan1 mesa-vulkan-drivers vulkan-utils mesa-vulkan-drivers mesa-vulkan-drivers:i386
And that's it (mostly). If you want you may install the latest MESA drivers via the below PPA. It's not necessary but I guess it can't hurt (can it?). Each line is a separate command.
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo apt upgrade
