How to Customize Ubuntu With the Unity Tweak Tool

To install the Unity Tweak Tool open the Ubuntu Software Centre, by clicking on the suitcase icon on the launcher, and search for Unity Tweak.

Click the Install button in the top right corner and enter your password when it is requested.

To open the Tweak Tool open the Dash and search for Tweak. Click on the icon when it appears.

The Tweak Tool has a series of icons split into the following categories:

• Unity
• Window Manager
• Appearance
• System

The Unity category allows you to tweak the launcher, the search tool, the top panel, the switcher, web applications and a few miscellaneous items to do with Unity.

The Window Manager category allows you to tweak the general Window Manager, Workspace Settings, Window Spread, Window Snapping, ​Hot Corners and other miscellaneous Window Manager items.

The Appearance category allows you to tweak the theme, icons, cursors, fonts and window controls.

The System category allows you to tweak the desktop icons, security, and scrolling.

To customize the launcher behavior click on the launcher icon in the Unity tool.

The launcher behavior screen is split into three sections:

1. Behavior
2. Appearance
3. Icons

By default, the launcher is always visible. You can, however, maximize screen real estate by making the launcher hide until the mouse pointer is moved to either the left side or the top corner.

To do this simply slide the auto-hide to On. You can then choose a fade transition theme and choose whether the user should move the mouse to the left or the top corner for the launcher to appear.

There is a slider control which lets you adjust the sensitivity. 

Also in the behavior section is a checkbox which allows you to minimize applications when you click on them.

The appearance section lets you adjust the background of the launcher. 

There is a slider to adjust the transparency level and you can set the background based on the wallpaper or a solid color.

Finally, the icons section lets you change the icon sizes within the launcher.

You can also amend the animation when an urgent action is required or when an application is launched via the launcher. The options are wiggle, pulse or no animation.

By default icons only have a colored background when the application is open. You can adjust this behavior so that icons have a background in the following circumstances:

• All applications

Last but not least, you can choose to have a show desktop icon in the launcher. By default, this is turned off but you can change the slider to turn it On.
