powertop custom startup service

powertop-custom.md

on ubuntu 22.04 i need to have powertop run on startup as a service as powertop --auto-tune to set all devices on "good" power saving status but this also disables mouse and keyboard so its very annoying to have to wake up the device before using it again after 5 seconds

powertune.sh script sets all devices on powersave except usb

edit powertop.service to start yourt script in the correct location in ExecStart=(path to script) copy the service to: /etc/systemd/system/powertop.service

systemctl daemon-reload systemctl enable powertop.service

also look for help here: https://askubuntu.com/questions/112705/how-do-i-make-powertop-changes-permanent
