1. Install Gnome Shell

   GNOME Shell is the default interface in GNOME 3, and it’s a clear break from GNOME 2. Install Gnome Shell, run the following command:

   dnd-riyaniezt:~$ sudo apt-get install gnome-shell
   

   After the installation/upgrade completes, Log out and log in back with Gnome session.

2. Upgrade Gnome Shell 3.12

   GNOME 3.12 was released a while back but it wasn’t included by default in Ubuntu 14.04. Install GNOME 3.12, run the following command:

   dnd-riyaniezt:~$ sudo add-apt-repository ppa:gnome3-team/gnome3-staging
   dnd-riyaniezt:~$ sudo add-apt-repository ppa:gnome3-team/gnome3
   dnd-riyaniezt:~$ sudo apt-get update && sudo apt-get dist-upgrade
   

   To install all the GNOME 3 apps (GNOME Clocks, Maps, Music, Polari, etc.) that aren’t installed by default as well as the default GNOME Shell extensions and GNOME Tweak Tool (which I’m sure you’ll need later on), use the following command:

   dnd-riyaniezt:~$ sudo apt-get install bijiben polari gnome-clocks gnome-weather gnome-maps gnome-music gnome-photos gnome-documents gnome-contacts epiphany-browser gnome-sushi gnome-boxes gnome-shell-extensions gnome-tweak-tool
   

   After the installation/upgrade completes, restart your system.

3. Gnome shell Extension Not Running Automatic On Gnome Shell 3.12.2

   Since gnome-shell 3.10, gnome extensions are disabled by default at every boot. I need to launch Tweak Tool to enable theme by hand every time.

   To activate/enable all extensions every time at startup, Open a terminal and create the following configuration file :

   dnd-riyaniezt:~$ sudo gedit /bin/gnome-shell-enable-all-extensions.sh
   

   Add the following lines to this file:

   #!/bin/bash
   sleep 2s # just in case
   cd ~/.local/share/gnome-shell/extensions
   array=($(ls -l --time-style=long-iso | egrep '^d' | awk '{print $8}')) # get only the folder names from current path
   ext_list=$(printf "'%s',"  "${array[@]}") # rebuild the string
   ext_list=${ext_list%,} # Remove the final character of the variable
   gsettings set org.gnome.shell enabled-extensions "[${ext_list}]"
   

   Setting up permissions for the script file:

   dnd-riyaniezt:~$ sudo chmod +x /bin/gnome-shell-enable-all-extensions.sh
   

   At last, puts the command in startup gnome-session-properties:

   /bin/gnome-shell-enable-all-extensions.sh
   

4. Brightnes control not running (with Intel card in Ubuntu 14.04)

   Open a terminal and create the following configuration file, if it does not exist:

   dnd-riyaniezt:~$ sudo gedit /usr/share/X11/xorg.conf.d/20-intel.conf
   

   Add the following lines to this file:

   Section "Device"
           Identifier  "card0"
           Driver      "intel"
           Option      "Backlight"  "intel_backlight"
           BusID       "PCI:0:2:0"EndSection 
   

   Save it. Log out and log in back.

Good Luck ! <DnD>
