Package: gnome-power-manager Version: 2.22.1-3 Severity: critical Tags: patch Justification: causes serious data loss
Hi, on a fresh install gnome-power-manager 2.22.x first collects statistics on how the battery 'behaves' to create what it calls a profile. Once created this is used to predict how long the system can be used until the battery runs low. During the initial "learning phase" gnome-power-manager correctly detects a low battery situation but then decides not to execute the corresponding action (warning + suspend/powerdown). At this point the debug log states: "profile is not accurate. Not doing policy action" Essentially, it doesn't trust its statistics yet. This happens independently of how the various related gconf keys are set. Unfortunately, this is also true for 'use_time_for_policy' which, if false, I would expect to render the battery profile irrelevant. On my system it takes gnome-power-manager several days to collect enough data for it to trust the profile and actually shut the system down when the battery is low. Up until that point there's no protection from low battery conditions. The system will simply turn off. Any data that hasn't been written to disk is irrecoverably lost. In Ubuntu this is tracked in Launchpad #135548 [1]. A proposed patch [2] makes gnome-power-manager fall back to percentage based decisions while a new battery profile is built during the course of a certain number of apparently required learning cycles. I've been using a version of gnome-power-manager with both 11_policy_actions_fallback.patch and 12_fix_notification_messages.patch applied for several month - originally on Fedora 9 [3], now on Debian lenny/sid - and it fixes the problem for me and AFAICT doesn't cause any regressions. I believe there's also a patch in later upstream versions of gnome-power-manager to address the issue but I haven't had a chance to look into that yet. Please see if this can be fixed. It would be unfortunate if more people lost data to this bug.
