[Bug 995715] Re: X defaulting keyboard locale to US at login after upgrading distribution if a Logitech Unifying Receiver is plugged in

 

In my experience, a keyboard using Logitech Unified Receiver (k400) uses
different locale than the other (USB) keyboard during the login at
LightDM, even if both are connected before and during booting. After
login they begin using the same locale. (Mythbuntu 14.04 here)

Title:
  X defaulting keyboard locale to US at login after upgrading
  distribution if a Logitech Unifying Receiver is plugged in

Status in xserver-xorg-input-evdev package in Ubuntu:
  Confirmed

Bug description:
  After upgrading Kubuntu Oneiric to Precise, X locale is defaulted to
  en_US regardless of system-wide and user-specific options.

  I found out about this issue when I tried to login via the KDM greeter
  and it was not recognizing my password. I got pam authentication
  failures in the auth.log, but authorizations files were just fine. In
  fact, I could login from the console and within KDE itself. When I
  tried typing into the KDM username box, I found out that special
  characters were not corresponding to my it_IT layout. My password was
  including the special character @ that was typed as ; thus not
  accepting my password. I worked this around by changing password to
  not include any special character.

  I installed LightDM and the problem persisted, so I thought about an
  evdev bug.

  I posted this issue on the Kubuntu Forums at first, where you can find
  more information and logs [
  http://www.kubuntuforums.net/showthread.php?58623-Can-t-login-via-KDM-
  after-upgrading-to-Precise ].

  Recently, German users were experiencing the same problem [
  http://forum.ubuntuusers.de/topic/kein-login-in-kdm-nach-upgrade/ ]
  where I found out that the only thing in common is a wireless
  keyboard.

  I bought a Logitech K800 (which uses a Unifying Receiver) when I was
  running Oneiric, making this the first time I upgraded a distribution
  while a wireless keyboard is connected. If that happens to be the
  problem, it could mean that my keyboard locale was not recognized
  during the upgrade process.

  I'm attaching some configuration files and logs, please tell me if you
  need more information.
