Comment 11 for bug 735756

At least we've got some progress!

Do you get anything for the hotkeys that aren't working from keymap or input-events? You'll probably have to check a different input device than your AT keyboard. If findkeyboards doesn't show anything new use lsinput and look for a device named "Toshiba input device".

If you don't see events for the keys, check dmesg for strings like "toshiba_acpi: Unknown key" followed by a scancode value. If you're seeing these report back the scancodes and intended functions, and I can augment the scancodes toshiba_acpi knows about to include these keys.
