+Subject: [PATCH] Ambient Mode: Wait for compositor when sending enable/disable
+ request. Low power mode wouldn't activate properly after boot sometimes, this
+ is likely due to the compositor not being available at the time. So wait
+ until we know that the compositor is available (ready to receive DBus
+ messages).
