Impossible de basculer le pavé tactile avec xinput après la mise à jour d'Ubuntu

J'ai rencontré un dysfonctionnement étrange de mon pavé tactile et de mon xinput. Après une des dernières mises à jour (période du 07/11/14 au 14/07/14), mon pavé tactile a cessé d'être basculable lorsqu'il était manipulé avec xinput.

Système: Ubuntu 14.04, noyau 3.13.0-33 Lenovo Yoga 13 Touchpad Appareil: SynPS/2 Synaptics TouchPad

Ce que j'ai fait: 1) Système démarré -> le pavé tactile fonctionne 2) Propriétés vérifiées de XInput avec xinput --watch-props 12

MAIS: le pavé tactile ne réagit ni ne reprend sa fonction d'aucune façon. Re-run complet de xinput --watch-props 12 produit

Un chèque avec xinput --test 12 ne signale aucun événement.

Donc ... histoire courte: l'appareil a les mêmes valeurs qu'avant .. MAIS ne fonctionne plus.

J'ai également vérifié synclient -l mais la seule valeur importante "TouchpadOff" est définie sur "0". J'ai également désactivé l'option "désactiver lors de la frappe" dans gnome-control-center pour éviter toute interférence. ET j'ai vérifié le basculement activer-désactiver avec synclient touchpadoff=0 et synclient touchpadoff=1 qui fonctionne parfaitement. Et finalement, j'ai essayé de basculer le pavé tactile avec le petit bouton soigné sous "Souris/Pavé tactile" dans "gnome-control-center" qui, comme il crée les mêmes événements que moi, se traduit par les mêmes événements et résultats xiput.

La question est: Y a-t-il une autre valeur d'une autre application utilisée/responsable de l'activation/désactivation et .. s'il y a ... comment puis-je la retrouver?

Oh .. ah .. FYI: Touchpad reprend son travail après la reconnexion.

Merci beaucoup d'avoir lu jusqu'ici .. et à l'avance pour votre aide et votre soutien.

J'achète un clavier tactile Logitech Keyboard K400r ( http://www.logitech.com/es-es/product/wireless-touch-keyboard-k400r ). Fonctionne, mais j'utilise toujours une commande sur le terminal avec mon pavé tactile d'ordinateur portable Dell Inspiron 1750:

synclient LockedDrags=1

mais ne fonctionne pas sur logitech.

Maintenant je fais ça:

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)]

Je vois que Logitech est pressant, maintenant en ce moment j'écris avec eux. Ensuite, je mets sur le terminal:

Je ne connais pas l'entrée de cet appareil. Maintenant je mets sur le terminal:
