[Pkg-utopia-maintainers] Bug#810714: upower: CriticalPowerAction respects systemd inhibitors

[Vinothan Shankar]

Package: upower
Version: 0.99.3-1+b2
Severity: normal

Dear Maintainer,


   * What led up to the situation?

   Running a laptop on battery with the GNOME Shell extension
   "Caffeine" active and a fullscreen application running.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

     Continued using the computer without seeing any low-battery
     alerts due to aforementioned fullscreen applications.

   * What was the outcome of this action?

   Computer continued to run until battery was well below the
   "critical" threshold, then shut down.

   * What outcome did you expect instead?

   The machine should respect UPower's CriticalPowerAction (which in
   this case is set to the default HybridSleep).

   * Additional Notes

   I have confirmed that Caffeine is the trigger for this behaviour:
   With no full-screen applications running and Caffeine not manually
   activated, the same computer correctly enters hybrid sleep on
   critical battery.  It is fully able to resume in that case, as well
   as if sleep (hybrid or plain) or hibernate is activated manually,
   so that is not the issue.  Presumably, however, any other inhibitor
   would result in the same behaviour.

   Were it not for Caffeine's default behaviour of inhibiting suspend
   and lock automatically when an application is fullscreen, this
   would not be such a problem, but a fullscreen application will also
   mask any low-battery warnings, so (without some kind of hardware
   alert, the way some laptops start beeping at low power) the
   shutdown will come without warning and without the ease of resume
   provided by suspend, hibernate, or hybrid sleep.
