How to prevent my screen from either dimming or the screen-lock starting when watching YouTube?
- by Steven Roose
My screen brightness used to dim after a few seconds to preserve battery. This is default in Ubuntu 12.04. However when watching video it should not dim.
This works correctly when I watch videos using native applications like VLC. With in-browser video, however, the screen is not prevented from dimming.
This is very annoying as you have to move…
