[Bug 46948] [Laptop Regression] Kubuntu doesn't honour Fn Key request

[Stephan Hermann]

Public bug reported:

Binary package hint: kubuntu-desktop

Kubuntu, at this state, doesn't honour Fn Key Request (most likely ACPI Events). So e.g. Suspend/Hibernate/Mute etc. are not working correctly.
This is a serious regression in Dapper, because it was working in Breezy.

The tested laptop is a Canonical Sponsored Laptop Toshiba Portege R200
(https://wiki.ubuntu.com/LaptopTestingTeam/ToshibaPortegeR200). Neither
KLaptopDaemon nor any other application is supporting the dapper
introduced new functionality in acpi-utils.

What is the problem?

If you press an Fn Key e.g. Hibernate, you can see in /var/log/acpi the
event coming to acpid and acpid is triggering the correct script in the
/etc/acpi/ (e.g. hibernate == hibernatebtn.sh). The executed script is
calling the `acpi_fakekey $LINUX_KEYCODE_SETUP_FOR_ACTION` command. This
keycode is a linux keycode, which is catched nowhere inside Kubuntus
KDE.

Running the real e.g. hibernate.sh script in /etc/acpi/, hibernation,
suspend to ram etc. is working correctly without any problems.

This problem was discussed many of times and due to time problems it is
not fixed.

For releasing a 3 year LTS release for Kubuntu, with printed shipit cds,
this is a serious regression and does not show any confidence into
Kubuntu as KDE release for the user.

I file this bug not as a rant, but as a documentation. 
If we want to have a working Kubuntu release which is working 100% out of the box, we should think about fixing those regressions asap, and postponing the official Kubuntu release a couple of weeks more.

KLaptopDaemon needs to be tought to honour those acpi requests and/or we
have to adjust KMilo.
