Comment 78 for bug 145337

Issue is fixed, kmilo now receives fakekey-events and forwards to guidance-power-manager by a dcop call. guidance uses dbus in order to tell hald to actually change brightness.

changelog entry:

kdeutils (4:3.5.8-1ubuntu7) hardy; urgency=low

  * debian/patches/kubuntu_14_kmilo_powermanager.diff:
    Added Brightness Down & Up key actions (DCOP call to Guidance
    Power-Manager). Fixed all DCOP calls to recent change of
    application top level name (power-manager -> guidance).

Workaround for gutsy:

edit scripts in /etc/acpi to use dcop-calls instead of acpi_fakekey.
the dcop-commands by luka renko sometimes don't work until acpid is manually restarted (dcop can't attach to server).
the following calls work better as i see it:

dcop --all-sessions --all-users power-manager-`ps ax|grep -m 1 guidance|awk '{ print $1 }'` power-manager brightnessUp
dcop --all-sessions --all-users power-manager-`ps ax|grep -m 1 guidance|awk '{ print $1 }'` power-manager brightnessDown

I think this bug could now be closed.
