Keyboard quirk is required for Mitac 8050QDA Fn Volume keys to function.

Hi klerfayt,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/lucid.

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 374884

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Yes, this is still a problem in Lucid. But I can't give you any more information because the given command to collect more data gives me an error. I am not sure what I am doing wrong:

$ sudo apport-collect -p linux 374884
Usage: apport-gtk <report number>

apport-gtk: error: no such option: -p

Have you tried without the -p ?

$ sudo apport-collect linux 374884
Usage: apport-gtk <report number>

apport-gtk: error: You need to specify a report number to update

@klerfayt: Would it be possible for you to test the PPA fix below under 10.04, and confirm that it fixes the problem on your Mitac laptop? Thanks very much. -Kamal.

Ubuntu 10.04 Beta users can install a test fix for this problem from this PPA:
  https://launchpad.net/~kamalmostafa/+archive/lucid-volume-keys

Feedback to this bug report will be appreciated.

Enabled PPA, ran system update and rebooted
Fn volume up/down/mute still excibit same problem

@klerfayt: Thanks for testing the PPA -- next steps:

1. Lets try apport-collect again -- the proper syntax should be: sudo apport-collect 374884 (no "-p" or "linux").

2. Please verify that the the PPA actually got installed: apt-cache policy udev (should include "Installed: 151-8~kamal~volkeys0")

3. Please follow this procedure, which will help me identify the key codes associated with the problematic keys on your laptop:

$ dmesg | grep keyboard
[ 1.095041] input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input5
(Note the number N in "inputN" at the very end of the line, where mine above says 5)

$ sudo /lib/udev/keymap -i input/event5 <--- replace the "5" with whatever your N was above.
(Now press each of these keys once: mute, volumedown, volumeup, and finally "Esc" to finish -- paste the resulting output here).

@klerfayt: Thank you for posting the information. I have modified the PPA test fix (from comment #7). Please update again, verify that "apt-cache policy udev" shows the updated version (Installed: 151-8~kamal~volkeys1), reboot, and then check the volume keys behavior once again.

Fn + Volume up/down/mute work correctly now

@klerfayt: Excellent. Thanks for the confirmation that the PPA fix worked. Note however, that earlier today a new version of udev was released (not including this fix) which supersedes the PPA (and will therefore break your volume keys again). I have now updated the PPA version again to deal with that. You should check that "apt-cache policy udev" indicates that you now have "Installed: 151-9~kamal~volkeys1" and update again if not.

I am working on getting this fix permanently committed upstream.

apt-cache policy udev
udev:
  Installed: 151-9~kamal~volkeys1
  Candidate: 151-9~kamal~volkeys1

Confirming that Fn + volume up/down/mute keys still work without any problems after updating and rebooting.
Thanks.

Attached patch adds this model (MTC/product_version=="A0") to the common-volume-keys release quirk.
Prerequisite patches:
  common-volume-keys.patch from LP: #565459
  udev-151-12~kamal~volkeys1.patch from LP: #420473 (for diff context)

@klerfayt: Note that I have updated the PPA test fix once more. Please update and confirm that version udev (151-12~kamal~volkeys2) still fixes the problem on your Mitac laptop. Again, thank you very much for reporting the problem and for your continued help testing the fix while we work towards getting it merged.

all fn volume keys - volumeup/down/mute - are still working without issues

Fix pushed upstream:

http://git.kernel.org/?p=linux/hotplug/udev.git;a=commitdiff;h=23c455b887e039183a1b2d78305df7b9f1cdad73

This bug was fixed in the package udev - 151-12

---------------
udev (151-12) lucid; urgency=low

  * Cherrypick keymap fixes from trunk:
    - Unite laptop models needing common volume-key release quirk. Many laptop
      models need the same volume-key release quirk. Currently, two models
      have identical force-release-maps/ keymap files (dell-studio-1557 and
      fujitsu-amilo-si1848) and two more need to be added (Mitac and Coolbox
      QBook). This replaces the identical force-release-maps files with one
      'common-volume-keys' file to make adding new models easier.
      (LP: #565459)
    - Add force-release quirk for Coolbox QBook 270-02 (LP: #420473)
    - Add force-release quirk for Mitac 8050QDA (LP: #374884)
