Black screen Ubuntu MATE 20.04.1 LTS

[sukerman]

I installed latest image, updated all files. Ubuntu MATE is unusable on RP 3+ in graphical mode so I switched to text only mode with

sudo systemctl set-default multi-user.target

I rebooted and on the monitor I get normal Ubuntu text mode.

I then ran :

MHS35-show

The RP rebooted and the screen is just black.
