Caffeine

https://launchpad.net/caffeine/

Caffeine is a small daemon that prevents the desktop from becoming idle (and hence the screen saver and/or blanker from activating) when the active window is full-screen.

Also provided are an indicator, caffeine-indicator, that gives a manual toggle, and caffeinate, which allows desktop idleness to be inhibited for the duration of any command. See their man pages for more information.

If you think you’ve found a bug

Try running, in a terminal:

window_id=`xwininfo | grep "Window id" | cut -d " " -f 4`

Now click on the terminal window, and then run:

xdg-screensaver suspend $window_id
xdg-screensaver resume $window_id

This performs the same steps at a lower level as turning Caffeine on then off again manually. If this gives the same problem as using Caffeine, then the bug is definitely not in Caffeine.

Testing translations

If you want to test out a translation without changing the language for the whole session, run caffeine as e.g.: LANGUAGE=ru ./caffeine

To compile the translations: ./update_translations.py (this is done automatically when building the package, so no need to do it normally).

You will need a language pack for the given language. Be aware that some stock items will not be translated unless you log in with a given language.
