Não é possível alternar o touchpad com xinput após a atualização do Ubuntu

Question

Eu encontrei um mau funcionamento estranho do meu touchpad e xinput. Depois de uma das atualizações mais recentes (período de 07/11/14 a 14/07/14), meu touchpad deixou de ser alternável quando manipulado com xinput.

Sistema: Ubuntu 14.04, Kernel 3.13.0-33 Lenovo Yoga 13 TouchpadDevice: SynPS / 2 Synaptics TouchPad

Saída de xinput list

    Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]

O que eu fiz: 1) inicializado sistema - > funciona com touchpad 2) Propriedades verificadas de XInput com xinput --watch-props 12

Uma verificação com xinput --test 12 não está relatando nenhum evento.

Então ... longa história curta: O dispositivo tem os mesmos valores de antes ... MAS não está mais funcionando.

Também verifiquei synclient -l , mas o único valor importante "TouchpadOff" está definido em "0" Eu também desabilitei a opção "desabilitar enquanto digito" no gnome-control-center para evitar qualquer interferência. E eu verifiquei o enable-disable toggling com synclient touchpadoff=0 e synclient touchpadoff=1 , que funciona sem falhas. E finalmente tentei alternar o touchpad com o pequeno botão em "Mouse / Touchpad" no "gnome-control-center" que, ao criar os mesmos eventos que eu, resulta nos mesmos eventos e resultados xiput.

A pergunta é: Existe algum outro valor de qualquer outro aplicativo que seja usado / responsável pela ativação / desativação e ... se houver ... como posso rastreá-lo?

Ah .. ah .. FYI: Touchpad retoma seu trabalho após o relogging.

Muito obrigado por ler isso até agora ... e com antecedência por sua ajuda, um suporte.

Eu compro um teclado Logitech Keyboard Touchpad K400r ( link ). Trabalhando, mas sempre uso um comando no terminal com meu touchpad laptop Dell Inspiron 1750:

synclient LockedDrags=1

mas não está funcionando na logitech.

Agora eu faço isso:

wachin@wachin-id:~$ xinput list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Logitech Unifying Device. Wireless PID:4024 id=10 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Video Bus id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ Integrated_Webcam_1.3M id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)] ↳ Dell WMI hotkeys id=13 [slave keyboard (3)]

Eu vejo que a Logitech é pressionada, agora, neste momento, estou escrevendo com eles. Em seguida, coloco o terminal:

Eu não sei o tipo de entrada para este dispositivo. Agora eu coloco no terminal:

xinput list-props "Logitech Unifying Device. Wireless PID:4024" "Synaptics Locked Drags" 1

e disse isso:
