Comment 305 for bug 1220426

Note: Bug is still alive in october 2015 - that is nearly 25 months old !

== My config
Fully up to date 14.04.
Nvidia GTX 950M + Integrated Intel
Asus ROG G551J
Elantech Touchpad

== Elantech Touchpad, the common hardware
After seeking on the net, I've find (here: https://devtalk.nvidia.com/default/topic/766166/elantech-touchpad-related-nvidia-driver-freeze/) that many people who experience the bug have an Elantech Touchpad and are using the synaptics drivers.

To check if you're in the same situation:
$ cat /sys/class/input/mouse0/device/name
->> ETPS/2 Elantech Touchpad

== Proposed workaround

It seems that the following workaround works, although I can't promise anything. We are however all expecting that NVidia developers fix their drivers properly.

    $ sudo apt-get remove xserver-xorg-input-synaptics-{your-flavour}
    $ sudo apt-get install xserver-xorg-input-mtrack-{your-flavour}

Hope you're doing better with that solution ;-)
