Comment corriger le problème de touchpad (synaptics) sur Acer aspire v 13? Parfois, le curseur saute comme un fou

Parfois, le curseur commence à sauter ici et là (très rapidement). La désactivation et l'activation du pavé tactile sont utiles, mais pour une courte période.

xubuntu 15.04, 3.19.0-30-generic

"xinput list" indique que le pointeur principal est UNKNOWN

user@laptop:~$ xinput list
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Logitech USB Optical Mouse                id=11   [slave  pointer  (2)]
⎜   ↳ SYN1B7F:00 06CB:2991 UNKNOWN              id=13   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
---

Y a-t-il quelque chose que je puisse faire?

J'ai ce même ordinateur portable, utilisez-vous UEFI ou le bios? Le bios (mode hérité) de cet ordinateur portable est défectueux et pose des problèmes de pavé tactile.

J'ai résolu le problème avec une meilleure isolation du trackpad. J'ai un Acer TMB-115M similaire à Aspire V3-111, la batterie se trouvant à l'intérieur du trackpad. Il y a un phénomène de résonance qui crée un problème de saut.

Normalement, le trackpad avec le cadre pour ordinateur portable est mieux intégré au service afin de résoudre ce problème.

Donc, mettre un ruban isolant ou du caoutchouc entre la batterie et le trackpad a résolu mon problème de saut.
