Using Caffeine With Ubuntu or Other Linux Distribution
Caffeine is an application that can be used to ensure that your monitor stays active. Although you can disable the screen saver and sleep functionality, caffeine is still another option which you can use at your leisure. This way, you can open and use caffeine only when you want to make sure the monitor will not sleep and stays active. One instance you may want this to occur is for watching movies.
