Comment 115 for bug 271706

On a Toshiba Satellite Pro U300 laptop (and others with the Pro series), there
is a volume dial on the side of the laptop, which is used to control the sound
volume.

It works on Fedora GNOME 2.22.1, but incorrectly.

Even slightest move up of the dial, moves the volume all the way up. The volume
control beside the clock shows the setting is in effect, also the volume icon
popup shows the volume all the way up.

The same happens with even slightest move the volume dial down. It turns the
volume all the way down, showing the mute sound icon beside the clock on the
panel and on the popup.

Aditionally the move breaks the keyboard handling. After the volume all up/down
keyboard is left in a non-working state. The signalling is still on because the
volume popup stil shows and disappears consistenly showing the max/mute icon.

I tried to see what keycodes the volume dial sends using 'xev', but since the
keayboard handling breaks during the dial move, I couldn't get much information
of it.

To get my keyboard working back, I need to switch to text console (Ctrl-Alt-F1)
and back to graphical console (Alt-F7).
