Bumblebee is only a workaround. If you use the nvidia gpu with the
proprietary drivers with it, it will exhibit the same behaviour if an
application uses the nvidia GPU, from what I've heard. Furthermore,
Bumblebee does not have perfectly working optimus support. It appears to
be bottlenecked somewhere that is not the GPU for me, probably because
of virtualgl silliness. I appreciate the hint for anyone who's locking
for a sort-of workaround, but I don't think it's time to lose hope just
yet.

@bluevector: this is not a problem with opensource (as the nvidia driver
is closed source) and it is not a problem with Intel graphics (as the
nvidia drivers are causing the problem). It's entirely nvidia's job to
fix it, as they've chosen to keep their drivers closed source, and thus
forbidden everyone but them to fix the bug. It's entirely a problem
caused by proprietary software. Please direct your hate-beams at nvidia.

  [nvidia-prime]Freeze while using touchpad

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.
