[PATCH 01/10] compositor: Track idle as a per-seat property

Bryce Harrington bryce at osg.samsung.com
Sat Mar 5 00:18:38 UTC 2016


Instead of having a single global idle tracker, track idling separately
for each seat.  Still treat inhibition on any one seat as inhibiting
the screensaver globally, for now.
