Jonathan's notes from talking to mjg59 KubuntuLaptopNotes

Summary

Make sure power management in Kubuntu is as good as it is in Ubuntu

Rationale

Power management in Kubuntu is flaky and unreliable. We should make sure it is a reliable as possible.

Use cases

Maisie wants to suspend her laptop but it doesn't work currently with Kubuntu.

Scope

Find the best programme for the job and fix it up for Kubuntu.

Design

Implementation

Code

Data preservation and migration

Outstanding issues

BoF agenda and discussion

What are planned changes in Ubuntu laptop support for Edgy (kernel/swsusp/uswsusp, powernowd, acpi-support, hotkey-setup, laptop-mode-tools, hal, pmi, )? Kubuntu should follow developments there as close as possible in order not to increase the gap between Ubuntu and Kubuntu laptop support.

KLaptopdaemon or KPowersave? More info on KubuntuPowersave page.

  • KLaptopdaemon directly works with /proc FS (acpi, apm) -> need to switch to hal (will work on more HW)

  • KLaptopdaemon config module is cluttered and complex -> needs simplification and good defaults (+autoconfiguration)

  • KLaptopdaemon is missing nice-to-have features of KPowersave (brightness control, scheme...)

  • Powersave uses own scripts for power management -> need to use acpi-support/pmi/laptop-mode-tools as base (will work on more HW)

  • KPowersave would need configuration module (kde-guidance?) to replace yast2 used in SuSE (+good defaults and autodetection)

Should work out the box and make use of Ubuntu work as much as possible.

Should offer stuff like a nice slider to dim the display.

Should integrate Suspend/Hibernate into KDE logout dialog - [https://wiki.kubuntu.org/KubuntuPowersave#head-ad7d472db3598a4e26e2854d975e69be09f94cb6 see proposed patch].

Should recieve wider community testing as part of LaptopTestingTeam (e.g. Canonical supplied laptops should be tested also with Kubuntu).

More info on power management: useful reading on [http://lwn.net/Articles/181888/ LWN].
