Hello Linux Geeksters. As you may know, Caffeine is an interesting app that prevents the activation of screensaver or lock screen when full screen windows are opened.

Unfortunately, the latest versions of Caffeine do not come with the AppIndicator that allowed the users toggle the screensaver, so a third party developer has forked it under the name of Caffeine Plus, which has the features of Caffeine 2.7 (prevents the screensaver to appear when full screen apps are opened) + a the toggle screensaver AppIndicator.
The latest version available is Caffeine Plus 2.7.2, which has been added to the WebUpd8 PPA from its Git repository, coming with the below changes:
- Fix a crash when there is no active window
- Fix Caffeine not terminating when the session ends
- Fix a crash when a window disappears during full-screen check
In this article I will show you how to install Caffeine Plus 2.7.2 on Ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr, Linux Mint 17.1 Rebecca, Linux Mint 17 Qiana, Pinguy OS 14.04, Elementary OS 0.3 Freya, Linux Lite 2.0, LXLE 14.04, Peppermint Five, Deepin 2014 and other Ubuntu 14.04 derivative systems.
Because it is available via PPA, installing Caffeine Plus 2.7.2 on Ubuntu 14.10, Ubuntu 14.04 and derivative systems is easy. All you have to do is add the ppa to your system, update the local repository index and install the caffeine-plus package. Like this:
$ sudo add-apt-repository ppa:nilarimogard/webupd8
$ sudo apt-get update
$ sudo apt-get install caffeine-plus
Optional, to remove caffeine-plus, do:
$ sudo apt-get remove caffeine-plus
