no power saving on login screen

[jfaberna]

I have Ubuntu 20.04 on a ASRock 1165G7 NUC with 2 monitors and running the OEM kernel. If I'm logged into my account the system will properly go into power savings and blank and power off the monitors. However, if I logout the computer sits at the login screen and blanks the monitors after the timeout but does not power off the monitors.

I can't find the setting to control powering off the monitors at the login screen.

I don't think it would be a good idea to have such a feature.
Sometimes boot and shut down can take quite a long time.
(think of W10 updates).
And in such cases display can tell useful information instead of :
"Don't turn off your computer".
You can use auto login for a dedicated user.

logging in is a security issue. auto login is not allowed.
Booting is under 10 seconds.
I would never run W10.
