I noticed a problem with my keyboards mute/unmute button. It seems that it only mutes, but the solution is simple.
Do the following, edit the .config/openbox/lubuntu-rc.xml with nano.

sudo nano .config/openbox/lubuntu-rc.xml

scroll down untill you see this

<!-- Keybinding for Volume management -->
  <keybind key="XF86AudioRaiseVolume">
    <action name="Execute">
      <command>amixer -q sset Master 3%+ unmute</command>
    </action>
  </keybind>
  <keybind key="XF86AudioLowerVolume">
    <action name="Execute">
      <command>amixer -q sset Master 3%- unmute</command>
    </action>
  </keybind>
  <keybind key="XF86AudioMute">
    <action name="Execute">
      <command>amixer -q sset Master toggle</command>
    </action>
  </keybind>

and type in the following: -D pulse after the -q so it looks like this

<!-- Keybinding for Volume management -->
  <keybind key="XF86AudioRaiseVolume">
    <action name="Execute">
      <command>amixer -q -D pulse sset Master 3%+ unmute</command>
    </action>
  </keybind>
  <keybind key="XF86AudioLowerVolume">
    <action name="Execute">
      <command>amixer -q -D pulse sset Master 3%- unmute</command>
    </action>
  </keybind>
  <keybind key="XF86AudioMute">
    <action name="Execute">
      <command>amixer -q -D pulse sset Master toggle</command>
    </action>
  </keybind>

reboot and done!

This is a simple guide to enable hibernation on Lubuntu.
It took me eight hours to fix, hopefully it wont take you this long.

1. Make sure you have a swap partition! NOTE SWAP PARTITION it’s much simpler.
   There are multiple guides online to setup the swap area,
   see this as an example: https://help.ubuntu.com/community/SwapFaq
2. Enable the hibernate buttons by editing this file:
   sudo nano /var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla[Disable hibernate by default in upower]
   Identity=unix-user:*
   Action=org.freedesktop.upower.hibernate
   ResultActive=no[Disable hibernate by default in logind]
   Identity=unix-user:*
   Action=org.freedesktop.login1.hibernate;org.freedesktop.login1.handle-hibernate-key;org.freedesktop.login1;org.freedesktop.login1.hibernate-multiple-sessions;org.freedesktop.login1.hibernate-ignore-inhibit
   ResultActive=noto ”yes”
3. We will be using s2disk for our hibernation, install it with he following command:
   apt–get install uswsusp

   If the configuration wizard doesn’t start automatically type:
   sudo dpkg-reconfigure uswsusp
   

4. Now we need to tell the system to use s2disk so do the following:

   cp /lib/systemd/system/systemd-hibernate.service /etc/systemd/system/

   cp /lib/systemd/system/systemd-hybrid-sleep.service /etc/systemd/system/

   And edit the /etc/systemd/system/systemd-hibernate.service

   [Service]

   Type=oneshot

   ExecStart=/bin/bash /opt/sleepscripts/s2disk.sh

   And /etc/systemd/system/systemd-hybrid-sleep.service
   [Service]

   Type=oneshot

   ExecStart=/bin/bash /opt/sleepscripts/s2both.sh
5. Restart, and it should work
