Wayland w/ Jetpack 4.2 and Ubuntu 18.04

Hi. I’ve got a Jetson TX2 with Ubuntu 18.04, and I have Wayland running on it by booting into the console and doing this:

mkdir /tmp/xdg
chmod 700 /tmp/xdg
sudo XDG_RUNTIME_DIR=/tmp/xdg weston-launch

Weston seems to come up great, but when I run vulkaninfo it lists the below instance extensions. Note that VK_KHR_wayland_surface is not listed, and xcb/xlib are.

Is there any way to get this working? Thank you very much for any assistance.

This is a known issue and will be fixed in next release.
