Public bug reported:
HP Pavillion desktop 2015 ufei date. Never turned off because boot takes too
long.
Screens (2) turned off system left on when not in use.
Up to Ubuntu 19 and early versions of 20 both screens came back on.
With latest update HDMI does not restart.
If boot from power off both screens, HDMI and VGA are ok. Turn screens off and
HDMI will not display.
I note that Windows (horrible) has a switch that allows the HDMI to be
controlled but Ubuntu did it automatically but won't now.
Suspend has always killed the HDMI but there is not much difference in
power consumption between on with suspend and on with screens off.
Hope you can help, booting from full power off takes too long.
