Comment 9 for bug 1334968

This happens also on a ZBook 15.

This is what showkeys outputs when I press F8, Fn-F8, Ctrl-C

$ sudo showkey -s
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
0x9c
^[[19~0x42
0xc2
 0x39 0xb9
0x1d
^Ccaught signal 2, cleaning up...

 $ sudo showkey -k
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode 28 release
^[[19~keycode 66 press
keycode 66 release
keycode 465 press
keycode 465 release
keycode 29 press
^Ccaught signal 2, cleaning up...

Fn-F8 doesn't do anything in showkey -s, it displays the 465 events in showkey -k

I'm on 12.04 LTS with the latest HWE kernel (almost, I should reboot to start using the 3.13.0-32.57~precise1 that came with the updates days ago).
