附：Unity 7.4.5 Update
The Unity 7.4.5 update isn’t big on new features but it is big on bug fixes and general all-round improvements.
While our original article on the update gives a more rounded overview of the changes on offer in this update, they can be summarised neatly:
General bug and performance fixes
A lock screen security fix
Improved low graphics mode
The New Low Graphics Mode in Unity
Unity gained a low graphics mode option a few years back. When enabled it disabled advanced window animations, Dash blur effects, and so on.
As well as disabling a couple of extra effects, the way you enable low graphics mode on Ubuntu changes with this Unity update.
Rather than use the CompizConfig Settings Manager (CCSM) app like before you now need to tweak a gsettings value.
Run the following command from the Terminal to enable low graphic mode in Unity 7.4.5:
gsettings set com.canonical.Unity lowgfx true
To undo/disable low graphics mode in Unity 7.4.5 run this command:
gsettings set com.canonical.Unity lowgfx false
Canonical added a low graphic mode option in the System Settings app in later versions of Unity, however feature doesn’t feature as part of this update.
You can view the raw change log if you want to cast an eye over every change, period and tilde involved.
How to Install Unity 7.4.5
The Unity 7.4.5 update is available to install on Ubuntu 16.04 LTS (only).
The update has begun rolling through the normal software channels but it may not be available to everyone right away.
To see if the update is available for you:
Launch ‘Software Updater’
Click ‘Check for Updates’
Install available updates
As the Unity desktop is a Compiz plugin you’ll will also find updates to other Unity desktop components, including Compiz and Nux, listed.
If you’re running a later version of Ubuntu with the Unity desktop you already have the bulk of the changes in this update as they’re either cherry picked from later releases, or are specific fixes for the Xenial Xerus.
