Trackpad cursor freezes on Ubuntu

Problem

When I move the cursor using the trackpad of my Aftershock notebook, it sometimes freezes in place. Keyboard still works. The problem happens only with trackpad, not with mouse. The only way to unfreeze the cursor is to switch to virtual terminal Ctrl + Alt + F1 and back to X Ctrl + Alt + F7.

Solution

Apparently, this is a common bug in Ubuntu as reported here. It happens only with NVIDIA drivers with NVIDIA graphics card. A fix has been created for the X Server here.

Until I move to a newer version of Ubuntu with this updated version of X Server, I will have to survive by switch to virtual terminal 😊

Tried with: NVIDIA 765M and Ubuntu 14.04
