Fn + up/down works only in mplayer

[jimmij]

I cannot set volume with function key (Fn+up/down). Other things like brightness (Fn+left/right) or NumLk (Fn+F11) works fine. The only place where Fn+up/down works is mplayer. I believe I should bind Fn+up/down to pcm or master in alsamixer, but how to do that?

Mplayer recognizes some multimedia keys (like XF86AudioRaiseVolume) out of the box, but configuring them outside specific applications depends on the desktop environment you're using.

Personally, I use x11-misc/xbindkeys which is DE agnostic. In case you want to give it a try, here's a part of my ~/.xbindkeysrc as a tip on how to control the ALSA mixer (for card 0):

In fact I do not use any DE right now, just pure WM (sawfish). Under gnome Fn keys work fine, but I really hate recent gnome. I tried to use xmodmap which I believe is most basic way for linux, like

That's just it: you've told X that pressing 'a' should count as pressing 'XF86AudioMute', but neither Sawfish nor X is configured to do anything with it (except pass the keypress event to the active application). If, unlike mplayer, the application is not programmed to respond to XF86AudioMute, nothing will happen. That's why I suggested using xbindkeys to do something about those keypresses in my earlier post (or use the facilities of your WM, if it provides them).

By the way, your brightness keys probably work because they are recognized on a lower level (maybe ACPI or even hardware, It's the same on my laptop) and normal numlock behaviour is always the default.

OK, thanks for your help, it works.
