[Bug 1535219] Re: HP ZBook 15u mic mute button doesn't work

Fri Apr 8 10:11:33 UTC 2016

This bug was fixed in the package systemd - 229-4ubuntu1

---------------
systemd (229-4ubuntu1) xenial; urgency=medium

  * Merge with Debian unstable. Remaining Ubuntu changes:
    - Hack to support system-image read-only /etc, and modify files in
      /etc/writable/ instead.

    Upgrade fixes, keep until 16.04 LTS release:
    - systemd Conflicts/Replaces/Provides systemd-services.
    - Remove obsolete systemd-logind upstart job.
    - Clean up obsolete /etc/udev/rules.d/README.
    - systemd.postinst: Migrate mountall specific fstab options to standard
      util-linux "nofail" option.
    - systemctl: Don't forward telinit u to upstart. This works around
      upstart's Restart() always reexec'ing /sbin/init on Restart(), even if
      that changes to point to systemd during the upgrade. This avoids running
      systemd during a dist-upgrade. (LP: #1430479)
    - Provide shutdown fallback for upstart. (LP: #1370329)
    - Break lvm (<< 2.02.133-1ubuntu1) and remove our dummy /etc/init.d/lvm2
      on upgrades, as it's shipped by lvm2 now.
    - Make udev break on mdadm << 3.3-2ubuntu3, as udev's init script dropped
      the "Provides: raid-mdadm".
    - Clean up /var/log/udev on upgrade (which is written under upstart, but
      not under systemd). (LP: #1537211)
    - Migrate existing s390x network configuration to new names. (LP: #1526808)
    - systemd.postinst: Bump Version comparison for migrating the UTC setting
      from /etc/default/rcS to /etc/adjtime, to run it for upgrades to 16.04.
    - VMWare BIOS reports implausibly high onboard numbers. This got fixed in
      upstream commit 6c1e69f9. Migrate names in ifupdown accordingly.
      (LP: #1550539)
    - udev: Don't kill peer processes if we don't run in a cgroup. This happens
      when running under/upgrading from upstart. udevd and everything else run
      in the root hierarchy on all controllers then, and the alleged cleanup of
      "our" cgroup becomes a system-wide killing spree. (LP: #1555237)

systemd (229-4) unstable; urgency=medium

  * Fix assertion crash when processing a (broken) device without a sysfs
    path. (Closes: #819290, LP: #1560695)
  * Fix crash when shutdown is issued from a non-tty. (LP: #1553040)
  * networkd: Stay running while any non-loopback interface is up.
    (Closes: #819414)
  * Fix reading uint32 D-Bus properties on big-endian.
  * Fix crash if an udev device has many tags or devlinks. (LP: #1564976)
  * systemctl, loginctl, etc.: Don't start polkit agent when running as root.
    (LP: #1565617)
  * keymap: Add Add HP ZBook (LP: #1535219) and HP ProBook 440 G3.
  * systemd.resource-control.5: Fix links to cgroup documentation on
    kernel.org. (Closes: #819970)
  * Install test-udev into libudev-dev, so that we have it available for
    autopkgtests.
  * Add "udev" autopkgtest for running the upstream test/udev-test.pl.

Title:
  HP ZBook 15u mic mute button doesn't work

Status in systemd package in Ubuntu:
  Fix Released

Bug description:
  This is mostly similar to this one:
  https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1334968

  I have an HP Zbook 15u laptop with a mic mute button at fn+f8. I
  didn't work for me with xubuntu LTS 14.04.03

  What is wished: keyboard shortcut fn+f8 should produce XF86AudioMicMute X key code which mutes microphone.
  What is happening: keyboard shotcut has keycode 465 which does nothing, while muting microphone through GUI enables led on the keyboard.

  How to debug similar issues and fix:
  Enable keyboard debug, find your scancode, remap it to f20, restart X.

  Now in step by step instruction:
  NB: keyboard sends scancodes, kernel makes keycodes from those. Keycodes are remapped in X before getting into applications

  1) enable keyboard debug to make things easier: edit /etc/default/grub, add the following options
  GRUB_CMDLINE_LINUX="atkbd.softraw=0", Reboot to enable this.
  2) install "evtest" utility
  3) using "evtest" find your keyboard (was /dev/input/event3 for me)
  4) look for the key down and key up scancodes for fn+f8 button. Fixed version looks like this:
  Event: time 1453101052.604985, -------------- SYN_REPORT ------------
  Event: time 1453101053.883744, type 4 (EV_MSC), code 3 (MSC_RAW), value e0
  Event: time 1453101053.883744, type 4 (EV_MSC), code 3 (MSC_RAW), value 01
  Event: time 1453101053.883744, type 4 (EV_MSC), code 4 (MSC_SCAN), value 81
  Event: time 1453101053.883744, type 1 (EV_KEY), code 190 (KEY_F20), value 1
  Event: time 1453101053.883744, -------------- SYN_REPORT ------------
  Event: time 1453101053.955411, type 4 (EV_MSC), code 3 (MSC_RAW), value e0
  Event: time 1453101053.955411, type 4 (EV_MSC), code 3 (MSC_RAW), value 81
  Event: time 1453101053.955411, type 4 (EV_MSC), code 4 (MSC_SCAN), value 81
  Event: time 1453101053.955411, type 1 (EV_KEY), code 190 (KEY_F20), value 0

  the "code 190 (KEY_F20)" will be different for you.

  5) using "eventX" from the above, find corresponding device using "find /sys/ -name event3". 
  6) find out udev modalias for your keyboard: "udevadm --debug test /devices/platform/i8042/serio0/input/input3/event3 2>&1 | grep dmi/id", The long path is from p.5 'find' output
  7) create and change /etc/udev/hwdb.d/60-hp-mic-mute-hotkey.hwdb file. Add following lines there:
  keyboard:dmi:bvnHewlett-Packard:bvrM71Ver.01.07:bd07/28/2015:svnHewlett-Packard:pnHPZBook15uG2:pvrA3009D510303:rvnHewlett-Packard:rn2216:rvrKBCVersion96.55:cvnHewlett-Packard:ct10:cvr:
   KEYBOARD_KEY_81=f20
  The long identifier is from udevadm point 6 output.  "81" is the scan code. f20 - is an alias for the keycode we wish to have (can be replaced with '190' keycode itself)
  8) udevadm hwdb --update; udevadm trigger /dev/input/event3
  9) test with evtest that you have appropriate keycode for the button. To make it work in X11 you have to restart X (or reboot, don't know for sure)
  10) test with xev after reboot: fn+f8 should work as intended this time. (xmodmap maps f20 to XF86AudioMicMute). 
  11) for xfce4 you might need to map XF86AudioMicMute to a pactl action, but this is xfce specific.

  For the maintainers:
  Mose of HPProBooks, EliteBooks, ZBooks has the same issue. Could anyone contact HP and request some help with all those keyboards?...

  Please, add ZBook into keyboard.hwdb file.
