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).

Summary

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

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.
