How to stop screen blanking during inactivity
Running -current, the screen goes black after a few minutes of inactivity, except when watching videos.
I'd like to disable this behaviour, but don't know how. Sometimes I want to read slowly or just watch a flash video and the screen blanking briefly interrupts me.
My window manager is ratpoison, but as this also happens when I'm using the TTYs, I don't think that's anything to do with it.
