Get the csf bin to lib/firmware

update/upgrade
sudo apt install ubuntu-desktop
reboot

Log in to wayland
sudo apt-get install glmark2-es2-wayland
glmark2-es2-wayland

This time runs no prob but before on 2x different try I got a total catastrophic lockup and decided to compile by waf myself.
Guess not waf but just a spurious crash.

Still get artefacts on the background image but always ignored that.

So dunno as tried it again expecting a crash and worked fine GLmark2 Score 872
