Suspend notification wakes external monitor.

[lb design]

Right before my laptop suspends gnome-shell shows a notification "Automatic suspend - Computer will suspend very soon because of inactivity" https://i.imgur.com/b4SxVk2.png

That notification wakes my external monitor only to present itself then suspends the laptop leaving the monitor to restart it's 30 min. turn off cycle. There should be a way to disable that notification.

1. Are you saying the external monitor was sleeping when the laptop screen wasn't?

2. Please report the issue to the upstream developers at:

   https://gitlab.gnome.org/GNOME/gnome-shell/-/issues

   and then tell us the new issue ID.

Created a new issue on gitlab.gnome.org #3021

The notification wakes my external monitor only to present itself then suspends the laptop leaving the monitor to restart it's 30 min. turn off cycle. My monitor is set to go black as I set in gnome-settings, then turn of after 30 min set on the monitor itself.

I might word that better. The external monitor goes black on inactivity and is on it's way to sleep only to be waken up by the suspend notification. Then it goes black again and have to wait 30 min before it goes to sleep.
