Laptop Keyboard Keys f1-f12 don't work

[xyzyndrome]

My laptop is an Hp Pavilion dv5-2135dx and its f keys have several special functions like
F1:has a ? mark
F2:Reduces screen brightness
F3:Increases scren brightness
F4:Sets and external monitor
F5:Previous track
F6:Pause/play
F7:Stop
F8:Next track
F9:Reduce volume
F10:Increases volume
F11:Mute
F12:Wifi

Whenever I press f3 and f2 I get the brightness functions working well but whenever I want to alt+f4, I don't get anything.
I also need the F keys to setup my sound card on ALSA but I just can't figure out what it is I need to fix here.

Here is some output:


setxkbmap -print -verbose 10
Setting verbose level to 10
locale is C
Applied rules from evdev:
model: hpdv5
layout: us
Trying to build keymap using the following components:
keycodes: evdev+aliases(qwerty)
types: complete
compat: complete
symbols: pc+us+inet(evdev)
geometry: hp(dv5)
xkb_keymap {
xkb_keycodes { include "evdev+aliases(qwerty)" };
xkb_types { include "complete" };
xkb_compat { include "complete" };
xkb_symbols { include "pc+us+inet(evdev)" };
xkb_geometry { include "hp(dv5)" };
};


Any help is appreciated.

Is there a Fn lock key on your board? Some keyboards have this and it changes the function of these keys. I don't knorr if this is your problem but it's one that kinda took me for surprise when I discovered it. Another thought, since it is a laptop, is that maybe the keyboard is set to use the alternate functions of these keys by default and you must hold a fn key for the normal functionality.

Which desktop environment are you using? (If any.) GNOME and KDE both should bind these keys appropriately by default, assuming they are recognized. Otherwise, you have to bind them to their various commands yourself.
