Comment 4 for bug 637695

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Please exercise the steps at https://wiki.ubuntu.com/Hotkeys/Troubleshooting to determine at which level your hotkey problems occur, and attach the collected information. Most probably the keys will produce an unknown or wrong key code with the "keymap" tool, in which case you need to follow /usr/share/doc/udev/README.keymap.txt.gz to determine the scan code - key code mapping for the broken/missing keys.

Thank you!
