ubuntu_wake

Instructions to wake ubuntu from suspend using only bluetooth and/or USB. TODO: confirm these steps work on a fresh installation.

on /etc/rc.local, put:

#!/bin/bash 

echo enabled > /sys/bus/usb/devices/usb3/power/wakeup

but pay attention to the usb3, check at lsusb I guess (https://jolahde.kapsi.fi/2018/02/05/enabling-usb-keyboard-and-mouse-to-wake-up-ubuntu-from-suspension/)

Disable autosuspend of bluetooth

Change the /etc/default/grub file and add the following line

GRUB_CMDLINE_LINUX="usbcore.autosuspend=-1"

then sudo update-grub
