Bug Description

Binary package hint: udev

Hi,

Volume control keys do not work reliably on my netbook (Coolbox QBook 270-02).

Those keys are pressed as a combination of Fn + right and Fn + left.

When I press any of them, sometimes they are ignored, sometimes they generate and endless number of keypress/keyrelease event pairs while the rest of the keys stop to work.

Attached is the output xev gets (after killing the gnome-settings-daemon) while I do some single keypresses

Below is the output from /lib/udev/keymap -i input/event4.

root@melon:/usr/share/doc/udev# /lib/udev/keymap -i input/event4

There's a possibility that the acpi-support scripts also catch these events and duplicate the key presses.

Can you please try

sudo dpkg -P acpi-support

and check if it still behaves the same?

However, that wouldn't explain the irregular behaviour you sometimes get, like endless number of repeats.

udev's keymap itself seems to be right here (or, rather, not affected at all), the key symbols seem to be correct. So if acpi-support isn't the culprit, this would be a kernel bug.

removing acpi-support did not cause any appreciable difference, I am still getting the same erratic behaviour.

Do you know if there is any utility similar to /lib/udev/keymap but able to generate more detailed info I could use to monitor everything the kernel sends to input/event4?

Cheers

You can try using input-events from the "input-utils" package, but it's not that much more detail.

This seems to be a kernel driver problem now, reassigning.

input-events shows that no "release" events are being generated for those keys!

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)
