From 79ead5309fe21e77cfe58adc6a9340953c2d52f4 Mon Sep 17 00:00:00 2001

Subject: [PATCH] power and media-keys: Use logind for suspending and
 rebooting the system

Use the new logind features to suspend and resume but making sure we opt out
of logind handling the sleep and power keys, and also inhibiting for lid close
auto-suspend if there is an external monitor connected.

Also use a delay inihibit for logind so that we can do actions on suspend like
blanking the screen using the screensaver and also poking the screensaver on
resume.
