Comment 6 for bug 558628

Thanks for the link. I tested Fn + F3, Fn + F10, Fn + F11 and Fn + F12. Some output:

1) With

xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'

no hotkeys is shown.

2) /lib/udev/findkeyboards
AT keyboard: input/event5

3) I will attach the output file of sudo /lib/udev/keymap input/event5 > /tmp/orig-map.txt
4) sudo /lib/udev/keymap -i input/event5 does not shown no one of these hotkeys (nothing appears)
5) cat /sys/class/dmi/id/sys_vendor
ASUSTeK Computer INC.
6) $ cat /sys/class/dmi/id/product_name
1001HA
7) I will atatch the file udevadm info --export-db > /tmp/udev-db.txt

I hope this serves you.
