I'm using an Optimus laptop (Asus N43SL)
nvidia-prime is installed, so my nvidia dedicated graphics card (GT 540m) is in use.
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.
