Caffeine Plus is a small daemon that prevents the desktop from becoming idle (and hence the screen saver and/or blanker from activating). It does this automatically when the active window is full-screen, or on demand when enabled through its system tray icon.

This is a fork of Caffeine 2.7 which restores the system tray icon for toggling it on and off. Manual toggling is the primary use case for many users, but the original author is unwilling to restore that functionality.

I don't know Python, so this is a bit of copypasta from Caffeine 2.5 and the AppIndicator docs.

• Any Linux desktop system that offers the org.freedesktop.ScreenSaver DBus API. This includes, but is not limited to, Linux Mint 16 and Ubuntu 14.04. Probably works on lots of older distributions, too.

• Python (Python 3 if you run it directly from the source tree w/o installing)

• apt-get install python-xlib gir1.2-appindicator3-0.1 (python3-xlib if running w/o installing)

• sudo python setup.py install --prefix /usr

• (optional) To have Caffeine Plus run on startup, add it to your System Settings => Startup Programs list.
