I'd like to put the built-in display into standby (E.G. xset dpms force off) and keep the display off even if the mouse moves. That is, I want to ignore mouse movement for the purposes of waking the display. How can I achieve this?

The use case is: I'm using Synergy to control other machines, and the built in display on the host generates a lot of heat. if I'm not actively using it, I'd like the display to sleep while focused on another machine.

The accepted answer in Can I force screen blank and ignore input? doesn't work for me because I want X11 to be able to receive mouse input, I just don't want that mouse input to wake the screen (I.E. that suggestion causes Synergy to lose access to the mouse input)

  • Thanks @StephenKitt I didn't find that one, not sure how... it's the exact same question. – Josh Jan 24 '18 at 15:57
  • You’re welcome. I’m not sure it will work with Synergy though :-/. – Stephen Kitt Jan 24 '18 at 16:01
  • @StephenKitt sadly, it doesn't work... then Synergy loses access to the mouse. It may be that what I want to do isn't possible... – Josh Jan 24 '18 at 16:02

    Right, I wondered as much. I’ll flag the question for re-opening. – Stephen Kitt Jan 24 '18 at 16:06
