Moode 4.2 Problem with 5" HDMI screen

[Tim Curtis]

You could try verifying that local ui is running and there are no obvious catastrophic errors or the like but as I mentioned earlier without one of these screens in hand I'm not able to attempt a repro.

systemctl status localui

Example from system running a Pi-Touch

Code:

pi@rp5:~ $ systemctl status localui
