Title:
  [nvidia-prime]Freeze while using touchpad

Status in X.Org X server:
  Confirmed
Status in xorg-server package in Ubuntu:
  New

Bug description:
  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.
