Volume buttons: The keyboard has Fn key combinations for screen
backlight and so on. The audio volume buttons are not bound into the
hardware and must be handled by Linux. Ubuntu’s Gnome envronment handles
this without pain. In KDE (also needed in other environments) I had to
make a .Xmodmap file with these contents:
keycode 160 = XF86AudioMute
keycode 174 = XF86AudioLowerVolume
keycode 176 = XF86AudioRaiseVolume
After running
xmodmap .Xmodmap
KDE handled the volume buttons just fine.
… This broke again under 2.6.15 because the ALSA driver for the sound
chipset names the channels as “Headphone” (actually the headphone
volume), “PCM” and “Internal Speaker”. The KDE mixer wants only to
manipulate the “Headphone” volume at this time. This has not been
important enough the figure out.
