Bug Description

Binary package hint: acpi-support

My thinkpad X40 has a blue "Access IBM" button above the keyboard which in previous Ubuntu releases I mapped to Lock Screen.
In hardy, the key event is not being detected by GNOME's Keyboard Shortcut preferences capplet.

acpid sees it:

[Fri Mar 7 15:39:13 2008] received event "ibm/hotkey HKEY 00000080 00001018"
[Fri Mar 7 15:39:13 2008] notifying client 11989[0:0]
[Fri Mar 7 15:39:13 2008] notifying client 17907[110:122]
[Fri Mar 7 15:39:13 2008] executing action "/etc/acpi/thinkpad-thinkpad.sh"
[Fri Mar 7 15:39:13 2008] BEGIN HANDLER MESSAGES
[Fri Mar 7 15:39:13 2008] END HANDLER MESSAGES
[Fri Mar 7 15:39:13 2008] action exited with status 0
[Fri Mar 7 15:39:13 2008] completed event "ibm/hotkey HKEY 00000080 00001018"

So, acpid does basically this in this event:
sudo acpi_fakekey 148

REPRODUCE:
1. start "xev" (from x11-utils) in a shell/terminal
2. arrange the xev window and terminal so that you can see events from xev in the shell window
3. in another shell execute "sleep 10; sudo acpi_fakekey 148"
4. Move the mouse cursor/focus in the xev window
5. Check if a KeyPress and KeyRelease gets displayed when the acpi_fakekey gets executed

FWIW, the exact same behaviour can be seen with the blue ThinkVantage button on a Thinkpad X300 running hardy.

Since I can reproduce this on two thinkpads I think it's worth confirming. I've also had it reproduced by an X61s user.

Same problem in IBM Thinkpad X41, Hardy uptodate, Access IBM Blue Button is not detected. In Gutsy it was working.

Also in Thinkpad R52, Hardy uptodate (18. 3. 08). The button is not detected by xev.

Has this regressed with acpi-support 0.106?
Please test it using acpi-support 0.105, which you can get from https://edge.launchpad.net/ubuntu/hardy/+source/acpi-support/0.105

I think it's older than that, 0.105 was published 5 days after this bug was filed.

I'm not even sure it's acpi-support. calling acpi_fakekey manually for that code does nothing. maybe something changed in X's keyboard bits?

Yes, I can confirm that bug, too (ThinkPad R51, Hardy up-to-date). But is it connected to acpi-support?
acpi_listen shows some output when I press the Access IBM Button here:

andi@work03-an:~$ acpi_listen
ibm/hotkey HKEY 00000080 00001018
ibm/hotkey HKEY 00000080 00001018
ibm/hotkey HKEY 00000080 00001018
ibm/hotkey HKEY 00000080 00001018

But xev is silent, though.
I did not test it in gutsy.

While "xev" in Gutsy displays an event for "sudo acpi_fakekey 148", in Hardy no event gets displayed.
Therefore I'm assigning the bug to xserver-xorg: I don't know if this is correct, but I think it's nearer to the root cause.

Bug is actually in the kernel.
acpi-support is a collection of scripts, acpi-fakekey works in 2.6.22
I also ran Xorg7.4/1.3 on 2.6.22, fakekey still works.

It's only when changing to 2.6.24 does it break. I don't think the problem is X ignoring the event, but the kernel actually dropping the fake input. Looking at the source, there aren't any X components linked in.
