Some older Sony Vaios have 2 graphics adapters, usually one from Intel
and one from nVidia (e.g. on the Vaio SZ650N, there is an Intel GM965
and an nVidia GeForce 8400M GS), which you can select with a hardware
switch when the notebook is off: so-called STAMINA and SPEED modes.

Ubuntu supports acceleration of both chips with open source (Intel) and
proprietary (nvidia) drivers, but installing both means that the 3D
setup gets clobbered.  The current workaround is to have two xorg.conf
files, one for each adapter, a couple of backed-up 3D libraries and a
script that selects the right combination.  The script in its current
state is specific to particular nvidia driver versions (even a minor
version change would break it), so is limited, but does work.

Jaunty is slightly more difficult to configure than Hardy as installing
nvidia-glx-180 removes /usr/lib/libGL.so.1.2 (needed for the Intel 965),
which is not replaced by simply reinstalling the deb for libgl1-mesa-
glx.  Instead, you have to extract the file manually from the deb and
copy it to /usr/lib.

vaio.html#video for details.
