I love tiling window managers. I tried i3wm the other day and loved it. However, I spent all day trying to get my multimedia keys to work. They never did. GNOME and Unity both recognize the key presses and perform the appropriate action.
I am using a laptop where I have to hit an FN key and then the key that I want. There are really only four keys that I care about:
FN + F9 = touchpad toggle
FN + F10 = mute sound
FN + F11 = lower volume
FN + F12 = increase volume
I want a tiling windows manager that has all of these keys working out of the box. I am done trying to mess around with config files. I have tried to get them to work and they continue to give me headaches.
