Em uma máquina Ubuntu 13.04, tenho os seguintes dispositivos de entrada:
$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech USB LaserStream(TM) Mouse id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Power Button id=7 [slave keyboard (3)]
↳ CHICONY HP Basic USB Keyboard id=8 [slave keyboard (3)]
↳ HP WMI hotkeys id=10 [slave keyboard (3)]
A configuração padrão do mouse é:
$ xinput list-props 9

Eu posso usar xinput set-prop 9 <num> <values>
para definir algumas das propriedades, por exemplo a propriedade Evdev Axis Swap
. Nesse caso, as alterações se aplicam imediatamente.
No entanto, se eu digitar o seguinte comando, o valor mudará na saída xinput, mas o comportamento de rolagem do mouse permanecerá o mesmo:
xinput set-prop 9 289 0 0 5 4
As outras propriedades Wheel Emulation
também não têm efeito. O que estou fazendo errado?
