I managed to bind the volume keys, but not the mute key.
The volume is indicated as being muted, so that's the first hurdle.
I've read about xev, but the mute key isn't recognised.
Then I tried xmodmap -pke, which gave me this (supposedly unassigned key):
keycode 121 = XF86AudioMute NoSymbol XF86AudioMute.
To get around xev not recognizing the mute key (even though xmodmap says it's
assigned somewhere),
I tried this:
in etc/defaults/grub, I changed
GRUB_CMDLINE_LINUX=""
to
GRUB_CMDLINE_LINUX="acpi_osi="Linux""
and updated grub with sudo update-grub.
No success.
I know I have Pulseaudio installed, but alsa isn't selected in synaptic.
I've read that it's supposed to be part of the kernel, so it should be there.
I might be missing drivers.
Still with the idea of keeping my system as lean as possible (even though
it's an X200), what could I try now?
