Introduction

If you have a laptop and the hotkeys don't work please follow the steps described here: LaptopTestingTeam/HotkeyResearch.

Problems with keyboard detection typically fall into one off these categories:

1. Your keyboard doesn't work at all.
2. Your USB keyboard stops working after a while.
3. Some keys of your keyboard don't work (as expected).

How to file a bug report

Keyboard related bugs should initially be filed against xserver-xorg-input-keyboard. If the bug turns out to be a kernel bug or a bug in another package, bug triagers will assign the bug additionally to that package and mark the xserver-xorg-input-keyboard task as invalid.

General information

For all bug categories the following general information should be provided:

1. How is your keyboard connected to your PC: DIN, PS/2, USB, USB wireless, ...

2. For a USB keyboard enter the following command on a terminal/console:

   $ lsusb -v > ~/lsusb-v 

3. Open a terminal/console and enter the following commands (minimal information as described in KernelTeamBugPolicies):

   $ uname -a > ~/uname-a
   $ cat /proc/version_signature > ~/version
   $ sudo lspci -vvnn > ~/lspci-vvnn 

4. Attach ~/lsusb-v, ~/uname-a, ~/version and ~/lspci-vvnn to the bug report as seperate attachments.

In case your keyboard doesn't work at all

1. Provide the [#generalinfo general information].

2. If you have a PS/2 keyboard make sure it was connected before booting Ubuntu.BRFor debugging you will need 2 computers in the same network. The second machine can be a Windows machine, in that case you need to install putty.exe from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html.

3. If you have a USB keyboard unplug it an plug it in again to see if it starts working again.

4. Enter the following commands in a terminal/console:

   $ dmesg > ~/dmesg 

5. Attach ~/dmesg and your /var/log/Xorg.0.log to the bug report in seperate attachments.

In case your keyboard stops working after a while

1. Provide the [#generalinfo general information].

2. Direct after GNOME, KDE or Xfce login open a terminal and enter the following commands:

   $ dmesg > ~/dmesg_boot
   $ cp /var/log/Xorg.0.log ~/Xorg.0.log 

3. Wait until your mouse stops working. If you have a USB mouse unplug it an plug it in again to see if your mouse starts working again.
4. Open a Virtual Terminal by pressing Ctrl-Alt-F1.

5. Enter the following commands:

   $ LANG=C
   $ dmesg > ~/dmesg
   $ diff -ns ~/dmesg_boot ~/dmesg > ~/dmesg_diff
   $ cp /var/log/Xorg.0.log ~/Xorg.0.log_tmp
   $ diff -ns ~/Xorg.0.log ~/Xorg.0.log_tmp > ~/Xorg.0.log_diff 

6. Attach dmesg_boot, dmesg_diff, Xorg.0.log and Xorg.0.log_diff to the bug report in separate attachments.

In case some keys of your keyboard don't work (as expected)

1. Provide the [#generalinfo general information].

2. Open a terminal/console and enter the following commands:

       $ xprop -root | grep XKB > ~/xprop 

   • $ gconftool-2 -R /desktop/gnome/peripherals/keyboard/kbd > ~/gconf }}}

3. Attach ~/xprop and ~/gconf to the bug report in seperate attachments.
