Nvidia GT820M Using Nvidia 340.29 installed via Additional Drivers in Settings.
Ubuntu 14.04 LTS.
It freezes when I try opening menus or some 5-10 minutes into using the
laptop. Using an external mouse, and laptop never freezes even for a
millisecond.
The mousepad is the culprit. If I don't use the mousepad, nothing
happen, even though its not disabled.
It doesn't bother me much, as I carry my bluetooth mouse with me
anywhere I go ('Blendering' sake) but will be nice to have a solution to
it.

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.
