There are a few methods to disable xscreensaver.
Disabling XScreenSaver
You can disable the screensaver directly from “run” option
- Either run the command: xscreensaver-command -exit
Installing Caffeine
- opening terminal
- running this line:
> sudo add-apt-repository ppa:caffeine-developers/ppa
> sudo apt-get upgrade
> sudo apt-get install caffeine
- adding new application called caffeine
- then launch it via applications
- when it starts, a cup of coffee will be in the task bar
- just click on it and activate on login as well as flash video embedded
You can also opt to download the deb file from launchpad and running it to install the application. https://launchpad.net/caffeine
Note
Caffeine for 2.8 and above does screen-lock automatically. If the window is full screen, caffeine will trigger. Please read my other post to control caffeine via icon for 2.8 and later.
