First, you need some cpu temperature monitor software. For Ubuntu you need to install a package called lm-sensors. It’s available in Ubuntu’s main repository. All the commands listed in this howto should be executed from the terminal. sudo apt-get install lm-sensors Then you need to run sensors-detect.
In today’s entry, I’m going to show how to edit the main menu in Ubuntu. More generally, this should be valid for anyone running the Gnome Desktop Manager. For this example, I’m going to add a new launcher for Firefox.
