HowTo: Install GNOME 3 Shell Extensions

Five must have Gnome shell extensions for Fedora 15 « Justin Stories

Earlier, I've blogged on the difficult to install weather extension (Rick Foos HowTo Blog: Gnome Shell Weather Extension ~ Web ...).

So how do you install GNOME 3 Shell Extensions?

First, Remember - Must Reset Desktop when Changing Shell Extensions
Alt-[F2], r

...Ubuntu is mostly the same with apt-get instead of yum...After you install the extensions, exactly the same...

# Install GUI to manage shell extensions.
yum -y install gnome-tweak-tool

# What are the available shell extensions?
yum list gnome-shell-extension-*

A list follows with some possibilities...

# If you're not one to mess around, install them all...You can always remove them later...
yum install gnome-shell-extension-*

# Enable/Disable Shell Extensions from a gui.

While many of them may not do what you expect, some are good.

Some extensions will need settings to be customized.

# Find where the settings for a shell extension are located.
# NOTE: Extensions may or may not have 'extension' in their schema name.
gsettings list-schemas

# Find the current settings, for an extension.
# if you have a keyword to grep, you can use that or copy one of the schemas from the list.
gsettings list-recursively $(gsettings list-schemas | grep weather) city '' position-in-panel 'center' show-comment-in-panel true show-text-in-panel true translate-condition true unit 'fahrenheit' use-symbolic-icons false woeid 'USTX0058'

# Find out what the valid settings are...
# Most useful for enums, otherwise just reports the data type and none exactly say what will happen...
gsettings range unit


# Change a setting
gsettings set unit 'fahrenheit'

Now you are an unintended expert in GNOME 3 shell extensions...This is a step backward, there was a GUI to add shell extensions in GNOME 2...I had no intention of becoming a shell extension expert...So I'm an unintended expert...
