Enable Ubuntu 18.04/22.04 hibernate

To make things easy: create a swap drive instead of using a swap file.
Then follow: https://fitzcarraldoblog.wordpress.com/2018/07/14/configuring-lubuntu-18-04-to-enable-hibernation-using-a-swap-file/

NOTE: don't use resumedelay because it'll increase the boot time.  Use resumedelay=1

Enable the hibernation menu:

sudo gedit /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
