My PC is running Ubuntu 22.04, with KDE Plasma 5.24. When I select Sleep from the Application Launcher, it always starts t go to sleep, but then it seems like a 50-50 chance that it will stay asleep. Many times, it wakes right back up again within 10 seconds. If I try to make it sleep two or more times, sometimes it will eventually sleep but not always.

I’ve done some searching and cannot find a resolution to this.

It seems I’m not the only one too - https://superuser.com/questions/1795451/kde-plasma-does-not-sleep

  1. Is there a sure-fire way to tell Ubuntu KDE to sleep?

  2. If not, what are some things which might wake it up again?

Thanks!

    Check the logs around that time. journalctl is your friend. Meticulously walk over the events from beginning to enter sleep to the wakeup. See where it stops sleeping and what event precedes it.
