The systemd service for use in ubuntu/debian linux with gnome session to periodically checks system inactivity and put system into sleep or hibernate

The hibernate should be configured as described in https://ubuntuhandbook.org/index.php/2021/08/enable-hibernate-ubuntu-21-10/

dependencies: systemd, gnome, rtcwake

install:

1. clone the repository

2. Follow the instruction https://ubuntuhandbook.org/index.php/2021/08/enable-hibernate-ubuntu-21-10/ to enable hibernation

3. edit hybrid-sleep.sh to:

3.1. set ALLOWED_IDLE_TIME and ALLOWED_IDLE_TIME_AC in milliseconds. After the ALLOWED_IDLE_TIME the pc will be put into sleep

3.2 set AC_SLEEP_TIME and BAT_SLEEP_TIME in minutes. The BAT_SLEEP_TIME is the time period after which the pc will be hibernated after putting into sleep. the behavior is similar to systemd suspend-then-hibernate service. The AC_SLEEP_TIME is used to periodically wake up to check if the pc is still connected to AC

4. run sudo ./install.sh

call sudo ./install.sh each time after changing values described in p 3.
