Linux alternative for Jiggler?

cfr · 2012-03-18 19:53:05

I'm wondering if there is a Linux alternative for Jiggler. Jiggler is a small OS X application which basically keeps your computer awake or your display from going to screensaver or switching off by "jiggling" the computer every so often if there has been no user activity. For example, you can tell it to "jiggle" every 2 minutes and it will then make sure that something happens at least every two minutes to keep the machine fully alert. You can also set it to "jiggle" only if certain applications are running although this bit isn't especially important to me - I don't think I ever used it.

What is nice about Jiggler is that you can start it when giving a presentation, for example, without having to reconfigure all of your energy-saving and display settings. If you then spend a while talking about a slide or in discussion, you don't have to keep returning to your laptop to bring the display back to life.

How about just run a script that toggles the dpms? That sounds like a much cleaner, saner and less hackish way.

Caffeine for gnome seems to be what you're looking for. http://aur.archlinux.org/packages.php?ID=29762

Couldn't have been more apt.

Thanks very much. I had no idea what dpms was. Man pages suggest that this concerns whether or not the computer controls the power state of a display. So if it is enabled for a display, blanking, sleep etc. will be triggered for that display after a certain time according to the system's standard power management configuration. If it is not enabled, these will not affect that particular display. Is that correct?

So I could essentially disable dpms for the relevant VGA display. (I'm not bothered if my laptop display goes to screensaver etc. - just that the main output on the screen doesn't disappear.)

Is it possible to do this by simply writing "Off" to /sys/devices/pci0000\:00/0000\:00\:02.0/drm/card0/card0-VGA-1/dpms? Or would that be much too easy or otherwise ill advised?
