lxde/xfce exit with error on start-up on rock64

I’ve been enjoying DietPi on my RPi3B+ and decided to try it on a Rock64. Sadly, after initial setup and installation of a gui (lxde/xfce/mate), the gui will not start.

Does anyone have any idea as to how to fix this? DietPi is so lightweight that it might actually make a satisfactory desktop so I’m intrigued to test it in that capacity.


This will be resolved in our next update v6.17, please see below for solution:
