when the freeze happens I switch to a terminal and then back to X:

https://devtalk.nvidia.com/default/topic/766166/elantech-touchpad-related-nvidia-driver-freeze/

sums it up...

[Vivian Stewart (vivichrist)]

So the quick fix would be:
1.) Run following command from terminal:
echo "options psmouse rate=60 resync_time=10" | sudo tee /etc/modprobe.d/psmouse.conf >/dev/null

2.) Reboot the system or reload psmouse module from terminal with following commands:
sudo modprobe -r psmouse && sudo modprobe psmouse

One of the psmouse attributes may be unnecessary

VIvian Stewart, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg 1387428

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful.

Thank you for your understanding.
