Jaunty Thinkpad fn-f7 does nothing (should toggle video)

Thank you for taking the time to report this bug and help to improve Ubuntu.

As a T60 user working on a hotkey-handling spec for Ubuntu this cycle, I've followed the status of ThinkPad hotkeys very closely. I can assure you that the hotkey event is being generated correctly in jaunty:

$ xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'
keycode 235 = (keysym 0x1008ff59, XF86Display), state = 0x10
keycode 235 = (keysym 0x1008ff59, XF86Display), state = 0x10
^C
$

If kubuntu is not handling the XF86Display key, that's a kubuntu-specific issue; reassigning accordingly.

Ah, Qt and KDE don't have support for the key yet. Opensuse has a few patches though.

openSUSE qt4 patch: https://api.opensuse.org/public/source/openSUSE:Factory/libqt4/display-key-support.diff
openSUSE kde4libs patch (4.2.0 based): https://api.opensuse.org/public/source/openSUSE:Factory/kdelibs4/display-key-support.diff

Those patches also needed a kdebase-workspace patch that is no longer applied to KDE. (We had the kdebase-workspace patch in 8,10 for randr support, but removed it in Jaunty since it introduced some severe bugs.)

So degrading to confirmed.

I have the same problem here. I am using Ubuntu Jaunty with the updates from Feb 25th 2009. When I do:

$ xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'

no keycode is returned for fn-f7 combination.

Any solutions?

Thanks

I posted a script in

https://bugs.launchpad.net/ubuntu/+source/kdebase-workspace/+bug/281284/comments/22

that takes care of this and a couple of other hotkeys.

The fn-f7 keys have now been aded the the KDE and Qt keymaps, but KDE still needs to make them actually do something. But this should be tracked upstream.
