The laptop has various special buttons to control the volume and CD playing. I haven't worried about getting the CD ones working, but I did want to get the volume buttons working; here's how to do it.
First, make sure you have the i8k code in your
kernel. You could, perhaps, compile
it as a module, but then you'd have to force it to always be
loaded; I just compiled it into the kernel itself. You can
check to see that it's installed by seeing if
/proc/i8k exists.
Next, download the i8kutils
package. Check to see if the Makefile is
appropriate; for me, KERNEL_SOURCE should have been
/usr/src/linux-2.4, but actually I doubt that would
have mattered when compiling it (since I wasn't compiling the
module from this package). Install it; make
install will put the utilities in
/usr/bin, so if you want them to go somewhere else,
just install them by hand. Also, do cp *.1
/usr/share/man/man1.
The main program to use is i8kbuttons. It's a
daemon that checks to see if the volume buttons are pressed, and
runs arbitrary code in response to presses. To start it, I
added the following line to /etc/rc.local:
/usr/local/bin/i8kbuttons -u "aumix -v +5" -d "aumix -v -5" -m "aumix -v 0" -r 100 &
(Note: the mute button is Fn-End.)
Like I said, I haven't worried too much about getting the other
buttons working; they don't require i8kbuttons to
support them, since they're regular keys. On my system, they're
keycodes 129-132 (you can check that with xev);
then you could use xmodmap to map them to keysyms
(e.g. to function keys F13-F16, or something), and then map them
to something (if you're using GNOME/Sawfish, look at Start
Here/Preferences/Sawfish window manager/Shortcuts).
