Bug Description

Testing oxide 1.1.0 from the phablet-team PPA, while playing back a video screen blanking happens, and I’m seeing the following message in the log:

[0704/163250:ERROR:object_proxy.cc(566)] Failed to call method: com.canonical.powerd.requestDisplayState: object_path= /com/canonical/powerd: org.freedesktop.DBus.Error.UnknownMethod: No such method 'requestDisplayState'
[0704/163250:ERROR:oxide_power_save_blocker.cc(116)] Failed to inhibit screen blanking

It appears the display handling was removed from powerd in version 0.16+14.10.20140620-0ubuntu1, apparently we should now invoke the unity D-Bus API for this:

    com.canonical.Unity.Screen
        /com/canonical/Unity/Screen
            com.canonical.Unity.Screen
                keepDisplayOn() -> int cookie
                removeDisplayOnRequest(int cookie)
