In terminal examples anything shown in bold is a comment and is not to be run, e.g:

sudo apt-get install fish # Then scratch your ear

So in the above # Then scratch your ear is not to be run in the terminal

In Unbuntu Unity editions the 'gconf-editor' has been replaced by the 'dconf-editor', a small difference but a frustrating one the first time you want to tweak the system. The dconf-editor retains the same look as its predecessor but many of the entries have changed names.

HOWTO: DISABLE:

Overlay Scrollbars and Revert To Classic Style

sudo apt-get remove overlay-scrollbar

Autorun Media

By default items such as optical media will autorun when placed in a drive, to disable this behaviour open 'dconf-editor' and locate the following key:

org.gnome.desktop.media-handling

Tick the box for 'autorun-never'

Keyboard Applet

System Settings -> Text Entry, uncheck "Show current input source in the menu bar".

Also while on this screen if desired you can remove any extraneous keyboard modes.

Global Menu

All Settings >> Appearance >> Behaviour (tab) >> Show the menu for a window >> Select 'In the window's title bar'

Login Sound

Go to the system icon in the top right hand corner of the screen (the icon to the left of your username), click on it and then click on 'Startup Applications'

In the 'Startup Applications Preferences' window under 'Additional startup programs' locate 'GNOME login sound' and untick the checkbox.

12.04 - Login sound has now been removed by default.

USB Drives from Automounting

By default any external USB drive when plugged in will be automatically mounted, to disable this behaviour run 'dconf-editor' locate the following key:

org.gnome.desktop.media-handling

Untick the box for 'automount' and 'automount open'

HOWTO: ENABLE:

Root User and Set Password

Unlike many other Linux distributions Ubuntu does not by default come with a Root (super user) account.

sudo -i
passwd root

Follow the prompts to add the password for root.

Lightdm To Allow Manual Logins

sudo nano /etc/lightdm/lightdm.conf

[SeatDefaults]
greeter-show-manual-login=true
greeter-hide-users=true

Save (CTRL+o) and exit (CTRL+x)

Close the terminal and restart system

Quicklists: An Overview

It is possible in Unity to edit the information seen when you right click on a launcher icon.

NOTES:

You can add whichever folder shortcuts to the launcher just ensure you follow the same formatting, i.e.

[Writer Shortcut Group]
Name=Writer
Exec=libreoffice -writer %U
TargetEnvironment=Unity

The entries at the end of the line 'X-Ayatana-Desktop-Shortcuts=' can be edited to show the shortcuts in whatever order you require; i.e. alphabetically.

The '[.... Shortcut Group]' entries do not have to match the order shown in the 'X-Ayatana-Desktop-Shortcuts=' line.

After editing Quick Lists you will need to log out/restart after your final edit before the tweak will become live.
