harvey186 Sorry I missed the mouse mention. The only other thing I can suggest is booting from the latest Budgie iso and see if it wakes up intermittently then. That might point to an issue with something you have done or with something an update has done.
It could be useful to try booting from another Linux distro entirely and see if random wakes happen with that. Nothing needs to be installed to do this and it might help identify where the fault is.

    Suspend mode or maybe hibernation?
    How do you activate it? By closing the lid or by command? Are there any wakeups configured in your BIOS? Wake on LAN, etc...?

      AlphaElwedritsch I'm talking about automatic suspend mode

      AlphaElwedritsch any wakeups configured in your BIOS?

      nope, as I have written, if I start the windows partition it works fine. So it has nothing to do with BIOS setup.

      AlphaElwedritsch By closing the lid

      If I close it, it will ever wake up again and I have to power off and reboot

        BuzzPCSOS It could be useful to try booting from another Linux distro

        there was a mint installed before. And with Mint I haven't had any issue

        OK, then it should be a Hardware specific issue or a budgie specific issue. Because it works for me without problems on my HP laptop on plasma and gnome.

        harvey186 Would help people with make and model
        But anyways turn off auto power save and see if it works.

        BuzzPCSOS What does that have to do with it?
        The problem is not that the laptop switches to suspend mode. It's that it automatically wakes up again.
        Switching this switch does not change this.

          I dont perform magic one way to know is for him to try it
          instead of debating it.

          AlphaElwedritsch An issue with me jumping in from a notification and confusing it with another thread where the user could not prevent the PC from going to sleep.
          Late night, still need to drink more coffee.
          The more you do the greater the chance of experiencing failure. The biggest failure is to not trying to do anything at all.

            (more times than I can count, eliminating variables is the path to success especially in linux)

            harvey186 Just some extra info see if your issue perssists with or without it plugged in
