Once in a while, my screen will freeze, only when I use my touchpad. This does not happen with my USB mouse. This does not happen either when I uninstall nvidia-prime and use my intel integrated graphics (HD3000). I can temporarily solve the issue by doing a VT switch. In the attached Xorg.0.log, you can see "synaptics: ETPS/2 Elantech Touchpad: touchpad found" each time I did a VT switch and regained control.
