Public bug reported:
Binary package hint: udev
Hotkeys of multimedia buttons get assigned same scan code 0x00 in sudo
/lib/udev/keymap -i input/event8
Like this:
> ~$ sudo /lib/udev/keymap -i input/event8
Press ESC to finish
scan code: 0x00 key code: screenlock
scan code: 0x00 key code: 14A
scan code: 0x00 key code: prog1
scan code: 0x00 key code: email
scan code: 0x00 key code: www
scan code: 0x00 key code: nextsong
scan code: 0x00 key code: previoussong
scan code: 0x00 key code: playpause
scan code: 0x00 key code: stopcd
Though the key codes differ are mostly correct (except for screenlock, which is
run key (fn+space) and 14A which is for touchpad turn on/off) and I am not sure
about prog1)
the keydump consists of single line:
> ~$ sudo /lib/udev/keymap input/event8
### evdev 1.0.0., driver 'Asus Laptop extra buttons'
acpi_listen detects the keys as:
> ~$ acpi_listen

This does not allow to change the key bindings as all scan codes are the same.
Expected behaviour: different scan codes
** Affects: udev (Ubuntu)
Importance: Undecided
