Disable screen power management except when screen is locked
I was wondering whether there was a way in i3 to disable any kind of display power management, like dimming the screen, letting it sleep, or starting a screen-saver, except for when the screen is locked.
The reason for asking is that I spend a lot of my day staring at text, and the screen suddenly going black really disrupts my workflow. However, I don't really mind if it goes to sleep when I have locked it and been away from my desk for a while, and because I'm using i3-lock it is probably less annoying for those working besides me that there isn't a glaring white screen lighting up their side view for hours. And because I use several machines with different underlying systems it would be would be great if there was a system-independent solution in i3.
