Comment 117 for bug 271706

This is not a kernel problem.

This volume dial sends normal multimedia keyboard VolumeUp and VolumeDown
keypresses. But I guess with some additional keycodes. In GNOME Keyboard
Shortcuts these are correctly identified as XF86AudioRaiseVolume and

Under textmode console there is no problem. Turning the volume wheel yelds some
~ characters on screen only, but the keyboard is still working.
Under XOrg, once I move the volume dial, keyboard is not working anymore. Maybe
it is switched to RAW mode or something? (I don't know the exact X internals).

So, this is more likely XOrg/GNOME problem, not kernel.

I would gladly help debugging it, but I do need some guidance.
