I'm using a Bluetooth touch enabled mouse with Ubuntu and notice that it has some extra keyboard mappings in it, that have no practical use for me. Left swipe on the mouse gives a 'd' and right swipe gives an Backspace. I have try to alter the key mapping with xinput and input-kdb but without any luck so far.

$ xinput list "ThinkPad Bluetooth Touch Mouse"

Disabling the buttons didn't help (mapping them to 0), the various characters were still generated.

Using input-kbd to make changes to the keymapping resulted in a error.

Creating a file with 0x70007 = 240 mapping the d to KEY_UNKNOWN causes a

$ sudo input-kdb -f keymap 6

scancode 458759 out of range (0-19)

Is there another way of mapping these keyboards input stemming from the mouse, somehow?
