[Bug 37139] Re: mouse movement wakes screensaver

[Timo Aaltonen]

comment by upstream:
"We ignore movements less than 50 pixels.  So, I don't understand why walking by
should deactivate the screensavers.  If the reporter is talking about DPMS
itself and not the screensaver window then that's another story.  Currently,
DPMS policy is handled within the X Server.  I don't know of any way to tell it
to ignore events.  Is that what the reporter is talking about?"
