    20 normal shutdown vs poweroff

    EDIT - see last post - artifact of "suspend".
    -



    I am plagued with frequent spontaneous restarts after I choose menu/shutdown.

    I have played with some settings but can find no relief.

    I started using sudo poweroff instead and so far get no restarts.

    Is this safe? It seems a bit more abrupt, but so far linux hasn't complained. Why isn't it always used?

    EDIT: this did not work - it's a suspend artifact.

    I saw that problem, in my case it was running 18.04 on a newly built Ryzen 2200G based desktop using the integrated video. I tried various fixes but was never able to solve the problem reliably. I kept tinkering until I broke the install. Installing 20.04 fixed the problems; newer kernel, newer ACPI and video firmware. I don't know that your problem has the same basis.

    Some googling seems to be problem for a few people, some have suggested wifi being on is one cause. Think I had similar problem years ago and had to blacklist a driver.

    This is actually a brand new build as I gparted wiped my SSD, rebuilt GPT, and redid win8, win10, and mint 20 to get good efi, mbr and system partitions. I have tried many things.

    uplug rj45 before shutdown.

    sudo ethtool -s enp0s25 wol d - but it just turns it back on.

    nmcli c modify "Wired connection 1" 802-3-ethernet.wake-on-lan ignore - but makes no difference.

    turn off all USB.

    share a fix so I can try it!!!

    It still does it 70% of the time.
    EXCEPT when I do sudo poweroff.

    EDIT
    this is an artifact of "suspend" in Ubuntu base.

    go to power mgt and change suspend to something else.
