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

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 a gap between Ubuntu and Kubuntu laptop support.
