My Ubuntu 12.04 Tweaks

This is just a list, partially for my reference, of the tweaks I'm using in Ubuntu 12.04. 

Install Gimp 2.8

1. Uninstall Gimp from your system:
sudo apt-get autoremove gimp gimp-plugin-registry

2. Add the following PPA:
sudo add-apt-repository ppa:otto-kesselgulasch/gimp
sudo apt-get update

3. Install Gimp:
sudo apt-get install gimp

Unity Minimize on Click

Add the PPA and get Unity with minimize on click patch using the following commands:
sudo add-apt-repository ppa:ojno/unity-minimize-on-click
sudo apt-get update
sudo apt-get upgrade

Install System Load Indicator

Install System Load Indicator in Ubuntu 12.04 LTS using the commands below:
sudo add-apt-repository ppa:indicator-multiload/stable-daily
sudo apt-get update
sudo apt-get install indicator-multiload

Install Jupiter (power saver)

Install Jupiter using the following commands:
sudo add-apt-repository ppa:webupd8team/jupiter
sudo apt-get update
sudo apt-get install jupiter

Integrate Google Calendar

Install "Lightning" and "Provider for Google Calendar" Thunderbird extensions.
sudo apt-get install xul-ext-lightning xul-ext-gdata-provider

Login to http://google.com/calendar, click the settings icon on the right and select Settings:
Now click on the "Calendars" tab and then on the calendar you want to sync with Thunderbird:
At the bottom of the calendar page, click the "XML" icon next to "Private Address" and copy the url:

 

In Thunderbird, select New > Calendar, then select "On the Network", choose "Google Calendar" and paste the link you've copied from Google Calendar:

 

When prompted, enter your Google account password. Next, you'll have to enter a name for the calendar, select a color, etc.:

 

Click "Next" and Thunderbird should start importing all your calendar events. This may take a while and the Thunderbird window may appear to freeze (but it's actually working in the background). In a few minutes (it depends on how many events you had in your calendar), Thunderbird should finish and the calendar you've added should be synchronized (2-way) with Google Calendar.

Get Global Menu for LibreOffice

Just like in the previous releases, LibreOffice doesn't use a global menu by default in Ubuntu 12.04 Precise Pangolin, but you can get it to make use of the global menu by installing the "lo-menubar" package:
sudo apt-get install lo-menubar

Install Ubuntu Tweak

To install the latet Ubuntu Tweak 0.7.0 which lets you edit quicklists, use the commands below:
sudo add-apt-repository ppa:tualatrix/ppa
sudo apt-get update
sudo apt-get install ubuntu-tweak

Enable Hibernation

you can enable hibernate in the Ubuntu power menu by running the following command in a terminal:
gksu gedit /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

And in the newly opened file, add the following:
[Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

Then save the file.

After logging out and logging back in, "Hibernate" should show up in the power menu.
