Ubuntu – Unity Panel Indicators

Here is a quick guide on how to install some useful Unity Panel Indicators, as well as instructions on how to remove them if you don’t like them. For other cool things to do with Ubuntu check out this article and this one too.

System Load / Performance

The system load indicator shows you graphs of your system performance on your panel – like the old GNOME System Monitor applet used to. It shows a graph of your CPU activity by default, but it can show graphs for more than one type of resource at a time – from its preferences, you can enable graphs for network activity, memory, and other system resources.

$ sudo apt-get install indicator-multiload

Launch this indicator from the Dash after installation.

CPU Frequency

The CPU frequency scaling indicator shows you the current speed of your CPU and lets you control its policy – for example, you can force a certain CPU speed, enable power-saving mode, or enable high-performance mode.

$ sudo apt-get install indicator-cpufreq

Launch the indicator by running the following command after installing it:

indicator-cpufreq

Classic Menu

The classic menu indicator provides a classic, GNOME 2-style menu on your panel in Unity. Install it with the following commands:

$ sudo apt-add-repository ppa:diesch/testing
$ sudo apt-get update
$ sudo apt-get install classicmenu-indicator

Launch ClassicMenu Indicator from the Dash after installing it.

My Weather Indicator

Open a terminal (Ctrl+Alt+T) and use the following commands:

$ sudo add-apt-repository ppa:atareao/atareao
$ sudo apt-get update
$ sudo apt-get install my-weather-indicator

Using My Weather Indicator

Open Unity Dash (press Windows Key) and search for weather. Start My Weather Indicator:

You can configure several things at first start such as using the source of weather information, units, locations etc. One thing you must do is to check the “autostart” from General Options tab to start My Weather Indicator at start up.

Recent Notifications

The recent notifications indicator provides a list of recent notifications that Ubuntu has shown to you – anything that came through the notification daemon appears here. You’ll be able to view all your recent notifications, even if you were away from your computer when they appeared.

$ sudo add-apt-repository ppa:jconti/recent-notifications
$ sudo apt-get update
$ sudo apt-get install indicator-notifications

Log out and log back in. The indicator will automatically appear.

Caffeine

The caffeine indicator allows you to prevent Ubuntu from going to sleep. For example, this may be useful if you’re watching videos in an application that doesn’t automatically inhibit Ubuntu’s sleep behaviour. Use the following commands to install it:

$ sudo add-apt-repository ppa:caffeine-developers/ppa
$ sudo apt-get update
$ sudo apt-get install caffeine

Launch Caffeine from the Dash after installing it.

Keylock

The keylock indicator applet shows you whether your caps lock, num lock, or scroll lock keys are on. Use these commands to install it:

$ sudo add-apt-repository ppa:tsbarnes/indicator-keylock
$ sudo apt-get update
$ sudo apt-get install indicator-keylock

Launch Indicator-Lockkeys from the dash after installing it.

Removing PPA’s

Use the –remove flag, similar to how the PPA was added:

$ sudo add-apt-repository –remove ppa:whatever/ppa

So for example, to remove the Indicator-Keylock PPA the command would look like this :

$ sudo add-apt-repository –remove ppa:tsbarnes/indicator-keylock

You can also remove PPAs by deleting the .list files from /etc/apt/sources.list.d directory.
