Steam Link, screensaver comes back on no matter what

When I use my Steam Link to connect to my Linux gaming rig, the screensaver keeps coming on and interrupting my gaming. I'm using xscreensaver because I love it (lots of fun screensavers), so asking me to stop using that, no thx.

My expectation is that my gaming rig would register the gamepad inputs I give and such so it doesn't think I'm "idle".

Can we get this handled? Shouldn't be too much work.
