The last version of Ubuntu, 11.04 introduced a new shell, Unity. This shell lets you install indicators, that will appear in the top right corner of the display. Though this shell looks a lot like the old Gnome 2 shell, you can’t install the old gnome indicators. Here are some useful Unity Indicators, that I install every time I put Ubuntu on a computer:
Weather Indicator
sudo add-apt-repository ppa:weather-indicator-team/ppa sudo apt-get update sudo apt-get install indicator-weather
CPU Frequency Indicator
sudo add-apt-repository ppa:artfwo/ppa sudo apt-get update sudo apt-get install indicator-cpufreq
Sysmonitor Indicator
sudo add-apt-repository ppa:indicator-multiload/stable-daily sudo apt-get update sudo apt-get install indicator-multiload
Workspaces Indicator
sudo add-apt-repository ppa:geod/ppa-geod sudo apt-get update sudo apt-get install indicator-workspaces
Use Startup Application Preferences, to make the indicators run when the computer starts.
Add: indicator-cpufreq, indicator-multiload
If you use other interesting Ubuntu 11.04 indicators, please leave a comment, so I can update the post!
