Thank you so much for your prompt reply; unfortunately it leaves me no
further ahead.
To clarify I run my system on solar power - battery/inverter, it's much
cleaner than the grid around here, and cheaper.
The computer is left turned on all the time but the monitors (2) are turned
off to save power.
When the monitors are turned back on HDMI does not come up. It used to on
older versions of Ubuntu but not now.
Hope this makes it a bit clearer.
