[Mauro S <1220426@xxxxxxxxxxxxxxxxxx>]

Clevo laptop, Ubuntu 14.10,  NVidia GEForce GTX870M with nvidia
331.113-update drivers (selected from system settings) plus Intel
integrated graphics, same issue.

VT switching and external USB mouse workarounds work.

I have another Clevo laptop identical but with NVidia GEForce GTX970M
instead, nouveau drivers, no freezes using touchpad.

Unfortunately I cannot try nouveau on GTX870M because isn't supported.

Any news about applying laurence's patch to xserver?

Title:
  [nvidia-prime]Freeze while using touchpad

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

Bug description:
  Using Asus N43SL laptop as an example, with nvidia-prime installed, so
  the dedicated NVIDIA graphics card (GT 540m) is in use, once in a
  while, my screen will freeze when I use my touchpad.

  WORKAROUND: Use USB mouse.

  WORKAROUND: Uninstall nvidia-prime and use integrated graphics.

  WORKAROUND: Do a VT switch via Ctrl+Alt+F1 then Ctrl+Alt+F7.

  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:
