Comment 24 for bug 1546641

I'm seeing this on a Sony Vaio VPCSB.

I'm also getting a problem with System Settings which may be related. Clicking on Power, the System Settings window freezes and then disappears. If I run unity-control-center from a terminal it prints the following as it dies:

libupower-glib-WARNING **: Couldn't connect to proxy: Error calling StartServiceByName for org.freedesktop.UPower: GDBus.Error:org.freedesktop.DBus.Error.TimedOut: Failed to activate service 'org.freedesktop.UPower': timed out
