Close, that is because of the wakeup. (I think)
See all of your devices that make your computer:
cat /proc/acpi/wakeup
Toggle all of them one by one:
echo GPP0 | sudo tee /proc/acpi/wakeup
(where GPP0 is the item in the left hand column)
Cat again if you want to see if it’s disabled
Keep going until you find the one that is ‘waking’ your computer back up after a sleep.
When you find the right one, add it to your crontab so it turns it off on every boot:
sudo crontab -e
@reboot echo "GPP0" > /proc/acpi/wakeup
I only found out about it recently. It is still pretty offensive, but in a hilarious way.
I did watch the dub, which based on some of the subs I’ve seen, the dub is filthier!
