If you'd like, try out our new live usb images for graphics testing from
here https://people.freebsd.org/~johalun/images/ They all come with all
versions of drm drivers, Xfce and Sway installed.

The 13.0-CURRENT one with drm-v5.0 drivers should have better support
for Vega graphics. Unfortunately it still comes with old Xorg so
Xwayland won't work properly. You'll need a 16GB memstick to fit the image.

These are still WIP so I'd really appreciate if you could test boot one
on your system and tell me how it works.

Thanks!
