"Going into standby mode" at shutdown?

General Linux Question
1

Get threefold statements at shutdown of computer:

  1. Scanning for signal…;
  2. No DP signal from your device;
  3. Going into standby mode.
    -computer then shuts down.

What gets me is no.3.
Had same message in Windows 11 and now with KDE Neon.
At least KDE shuts down much faster!
But why state ‘standby mode’ instead of simply ‘shutting down’ (which it does anyhow)?

I had a laptop which did that , both during bootup and during shutdown.
I cant remember exactly, but it turned out to be something to do with elogind and I had to edit some config file (maybe elogind.conf) to stop it.
If you want I can search out the details.

Thanks!

Will check that out for sure! :wink:

Have a look at this old topic, it is all in there

‘Recovering ubuntu 18.04 system password’

Okay… figured out how to root… but quite unsure as to what exactly needs to be modified.

I am unsure too. This is just something you could try, it may not fix your issue

  1. you need to find where the login daemon config file is. It might be
    /etc/elogind.conf or /etc/systemd/logind.conf
  2. then look at the last reply in that old topic, and try the mods I show there. Copy the file before you modify it, so you can easily reverse anything you change.

No guarantees

Turns out, that it’s the monitor and not the desktop that’s putting out those messages.
