So. I'm dumping this here since I'm running testing.
I can suspend fine - but just once. After I resume, I am not able to suspend anymore. Dbus says I'm not authorized. Curiously enough ck-list-sessions shows no authenticated sessions anymore either (which it normally does; normal output below).
Session1: unix-user = '1000' realname = 'Whoopsie Daisy' seat = 'Seat1' session-type = '' active = TRUE x11-display = ':0' x11-display-device = '/dev/tty3' display-device = '' remote-host-name = '' is-local = TRUE on-since = '2012-02-08T19:16:59.409512Z' login-session-id = '4294967295'
Restarting Dbus does not help, ck-list-sessions still returns nothing after that. Both consolekit and policykit are running.
So, any takers?
