I have a fresh install of 16.04 on a new Levono Ideapad 500S. I've been trying to make the brightness keys work and have finally managed to hook up the brightness up key to work as expected.
However, I need to change the keycode of my brightness down key in order for it to work, but
setkeycodes does not seem to be doing anything.
showkey and pressing the brightness down button thrice gives me:
$ 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 0xe0 0x6f 0xe0 0xef 0xe0 0x6f 0xe0 0xef 0xe0 0x6f 0xe0 0xef
which led me to believe that the scancode of it is
e06f. However, running
sudo setkeycodes e06f 224 and then running
showkey -k still shows the old key code (which was 112).
Can setkeycodes not override an already set keycode from some other source? If so, how can I change the brightness down key's keycode.
