It appears DPMS does not work with Xubuntu (19.10) on Raspberry Pi 4B.

The screen blanks but the HDMI monitor back light is still on (e.g. when the screen saver blanks or log out after DPMS configured)

Code:
xset dpms force off
does blank the screen but the backlight is still on.

This was a firmware issue but
Code:
tvservice -o
does switch off the hdmi and the back light goes off.
(Background info: I think this was fixed in Raspbian).

Any clues?
