Once upon a time, Linux desktops were full of wobbly windows, desktop
cubes, and other over-the-top graphical effects. Ubuntu still includes
the Compiz software that makes this possible, but it’s been toned down
by default.
Ubuntu includes some basic graphical effects on its desktop, but
provides no built-in option for enabling and tweaking more effects. All
you need is a third-party tool to unlock the advanced features in
Compiz.
This guide was written for Ubuntu 13.04, the latest version of Ubuntu
at the time. Some of the steps or commands may be a bit different on
other versions of Ubuntu.
Installing CCSM & More Plugins
To configure Compiz, we’ll need the CompizConfig Settings Manager, or
CCSM. You’ll probably also want to install additional plug-ins for
Compiz so you have more advanced effects to play with.
To install CCSM and the extra plug-ins, just open a Terminal window —
you’ll find the Terminal application in Ubuntu’s Dash — and run the
following commands:
sudo apt-get install compizconfig-settings-manager compiz-plugins-extra
Enter your password, type Y when prompted to confirm, and Ubuntu will
automatically download and install the appropriate software.
Using CCSM
You can now open the CompizConfig Settings Manager application and
use it to configure Compiz. Just open the dash and search for CCSM or
Compiz to find and launch it.
CCSM warns us that it’s an advanced tool that we could use to break
our Compiz configuration. If you do manage to break your Compiz desktop,
you can fix it by resetting it to its default values — we’ll cover that
later.
CCSM provides a long list of different plug-ins. You should leave
“system” plug-ins like “Gnome compatibility,” “Copy to texture,” and
“PNG” alone. The most interesting plug-ins for configuring desktop bling
are found under the Desktop and Effects categories.
To enable a plug-in, just click the check-box to the left of it. To
configure an enabled plug-in, click its name. Different plug-ins have a
wide variety of different options — everything from different animations
to customizable speeds and hotkeys, depending on the plug-in.
Enabling Wobbly Windows
Check the Wobbly Windows checkbox under Effects and you’ll be prompted to disable the Snapping Windows plug-in.
Enabling wobbly windows is that simple — your windows will now appear
to wobble as you drag them, as if they were made of jello. It looks
better animated.
If you wanted to configure this plug-in more, you could click the
Wobbly Windows name and adjust a variety of settings, such as the key
that makes windows snap to the edges of the screen when held — Shift by
default — and even the friction value.
Using the Desktop Cube
The desktop cube requires Ubuntu’s workspaces to be enabled. First, open the Appearance tool from Ubuntu’s Dash and check the Enable Workspaces option.
To use the desktop cube, which uses an animated cube-rotation effect
when you switch between virtual desktops, as if each of your virtual
desktops is located on the side of a three-dimensional cube, enable the
Rotate Cube checkbox. You’ll be prompted to enable the Desktop Cube
plug-in and disable the Desktop Wall plug-in, which is used by default.
You’ll now need to click the General Options button in the General section.
Click over to the Desktop Size tab, set Horizontal Virtual Size to 4, Vertical Virtual Size to 1, and Number of Desktops to 4.
Your desktop cube should now be working. Use Ctrl+Alt+Left or Right
to switch between cube faces, press Shift+Ctrl+Alt+Left or Right to move
windows between cube faces, or hold down Ctrl+Alt and left-click drag
to manually rotate around your cube.
Other Plugins
Some plugins are more practical than others. For example, the Water
Effect plug-in allows you to hold Ctrl+Super (Super is the Windows key)
and move your mouse to create a water-rippling effect that follows your
mouse. It also allows you to press Shift+F9 to toggle a rain effect that
makes your desktop appear as a pond rippling as raindrops fall on it.
You’ll find many other plug-ins in CCSM for everything from adding
enhanced zoom functions for accessibility to painting fire on your
screen for no other reason than to show off. Feel free to explore the
available plug-ins and options.
Resetting Compiz to its Default Settings
When you’re done messing around — or if you managed to break
something — you may want to go back to Ubuntu’s default Compiz settings.
To do so, press Ctrl+Alt+T to open a terminal window. This keyboard shortcut may even work if your desktop is somewhat broken.
Run the following command in the terminal window:
dconf reset -f /org/compiz/
Log out of your Ubuntu desktop, and then log back in — Compiz should be functioning just like it was after you installed Ubuntu.
