I've been playing around with the dpms/blanking settings on a version of Linux built via yocto.
Something odd I've noticed is that "blank" and "dpms off" both put the monitor to sleep. I had thought blanking would just, well, blank the screen, and not actually power off the monitor. Am I mistaken?
$ xset s blank $ xset s activate
$ xset dpms force off
What I'd like is to just blank the screen on a short interval and then actually power off the monitor after a longer interval. Perhaps I should look at a minimal black screensaver instead of using the built in blank.
