Classic windump is really buggy and you can't turn off the Nvidia GPU 
without crashing X. Therefore, I'll refrain from talking about it and 
put forth a more sane approach that use Bumblebee X Server. All 
instructions assume an Ubuntu or Ubuntu-like system and multiple 
terminal tabs/windows. Please note that the solution I put forth has 
plenty of its own bugs like wonky mouse pointers and not always being 
able to fullscreen the Nvidia windows.

For Nouveau (assuming that you have a recent enough kernel and mesa), 
the process is pretty much the same. Skip the first 2 steps, install 
Bumblebee with the --driver=nouveau flag, and use xorg.conf.nouveau. 
VDPAU will not be available.

* Install nvidia blob from distro repos: sudo apt-get install nvidia-current

* Override mesa manually if installing the blob doesn't (assuming 
64-bit, 32-bit is just gl_conf): sudo update-alternatives --config 
x86_64-linux-gnu_gl_conf

* Download and compile my branch of windump: 
https://github.com/LLStarks/hybrid-windump

* Download Bumblebee from git and checkout the common-debug-functions 
branch: https://github.com/Bumblebee-Project/Bumblebee/

* Install Bumblebee from git and replace /etc/bumblebee/xorg.conf.nvidia 
with the one from my windump tree. Change the resolution in said file to 
your native LCD resolution.

* Configure Bumblebee to use your ACPI calls if you so desire: 
https://github.com/Bumblebee-Project/Bumblebee/wiki/ACPI-Removed

* Start Bumblee X Server: sudo bumblebee --startx

* Start mplayer (I recommend SMPlayer for this since mplayer will 
respond to all terminal keypresses and go crazy): DISPLAY=:8 mplayer -vo 
vdpau filename

* Run windump in a window so it's easier to test. If you run without a 
window, you'll either need to use CTRL+C or killall windump to escape if 
it covers then entire screen: ./windump -w1 :8 :0

* Start the compositor last otherwise mplayer will bitch. We'll need it 
for VDPAU to render properly: xcompmgr -d :8

* When you're done: sudo bumblebee --stopx
