Hibernate GNOME extension

This is a stupid simple extension for enabling hibernation option for GNOME desktop environment

Before installation

IMPORTANT: this extension requires you to have configured and preinstalled some software!

Install components:
```
# for Debian based distros:
$ sudo apt install pm-utils hibernate
```
find and install pm-utils and hibernate for your system
Configure swap partition or swapfile: basically you need to have swap space with size like your RAM, or bigger Then you should find UUID of your swap (if you are using swap file, then swap file offset too) use:
```
# to get UUID:
$ findmnt -no UUID -T /path_to_your_swap
# to get swap file offset:
$ filefrag -v /swapfile | awk '{ if($1=="0:"){print substr($4, 1, length($4)-2)} }'
```
for more information see this

Grub configuration: edit /etc/default/grub file you need to find or add GRUB_CMDLINE_LINUX_DEFAULT option to this file Set UUID (and offset if you are using swapfile) like this:

# if you use swap partition:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=YOUR_VALUE"
# if you use swapfile:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=YOUR_VALUE resume_offset=YOUR_OFFSET"

Finally run:

$ sudo update-grub
$ reboot

Test hibernation: to test if hibernation works run this command:
```
$ sudo systemctl hibernate
```
If hibernation works, then you can install this extension, if not, google your problems...

Installation

Clone extension project:

$ git clone https://github.com/IntegerVector/hibernate-gnome-extension.git

run install script:

$ ./install

It will pull changes from main branch and install extension to you system, so it also updates extension

Finally, you can enable extension using "Extensions" app (or tweak tools in older GNOME versions).

Removing

turn extension off, then run remove script:

$ ./remove

then you can remove project folder.
