I ran gnome-power-manager with --verbose, and the log seems to provide some hints as to the nature of the problem. I see the following sequence of events:
[system_timer] gpm-idle.c:171 (23:38:29): System idle timeout [gpm_idle_set_mode] gpm-idle.c:98 (23:38:34): Doing a state transition: 3 [idle_changed_cb] gpm-manager.c:876 (23:38:34): Idle state changed: SYSTEM [gpm_inhibit_has_inhibit] gpm-inhibit.c:336 (23:38:34): Valid as no inhibitors Saving to syslog: Suspending computer. Reason: System idle.[gpm_info_event_log] gpm-info.c:594 (23:38:34): Adding 5 to the event log [gpm_control_get_lock_policy] gpm-control.c:389 (23:38:34): Using custom locking settings (1) [gpm_screensaver_lock] gpm-screensaver.c:250 (23:38:34): doing gnome-screensaver lock [gpm_control_suspend] gpm-control.c:439 (23:38:34): emitting sleep ** (gnome-power-manager:28309): WARNING **: Method failed (An unknown error occured) [gpm_control_suspend] gpm-control.c:447 (09:37:37): emitting resume [...] [gpm_control_suspend] gpm-control.c:451 (09:37:37): emitting sleep-failure [...] [idle_do_sleep] gpm-manager.c:813 (09:37:37): cannot suspend (error: General failure: An unknown error occured), so trying hibernate This shows: 1. The system being idle for the specified period of time, and gpm deciding to sleep 2. The system resuming some 10 hours later 3. gpm detecting a failure to suspend, though in fact it was suspended for 10 hours 4. gpm trying hibernation instead, still trying to satisfy the original request to suspend I see that others have seen the opposite, so it may fall back from hibernate to suspend as well. I'm attaching the complete log. ** Attachment added: "gnome-power-manager debug log" http://launchpadlibrarian.net/15370014/gnome-power-manager.log.gz -- Idle/inactive action/autosuspend results in a suspend AND a hibernate https://bugs.launchpad.net/bugs/136871 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
