For those affected and do not use a solution like Bumblebee
(https://github.com/Bumblebee-Project/Bumblebee), please run:

    update-alternatives --force --set i386-linux-gnu_gl_conf
/usr/lib/i386-linux-gnu/mesa/ld.so.conf

If you're running a 64-bit system, run:

    update-alternatives --force --set x86_64-linux-gnu_gl_conf
/usr/lib/x86_64-linux-gnu/mesa/ld.so.conf

This will set the default OpenGL library back to Mesa. Using a custom
Xorg configuration file, you can still utilize the nvidia drivers. Note
that Optimus is not supported for Linux so you've to use a solution like
Bumblebee or hybrid-windump.

Title:
  Recommended drivers don't work with Nvidia Optimus

Status in “jockey” package in Ubuntu:
  Confirmed

Bug description:
  Nvidia's hybrid graphics technology "Optimus" (combines GeForce with
  an Intel graphics chip) is currently not supported in the Nvidia Linux
  drivers. When you install the drivers Ubuntu won't startup into
  graphics mode anymore. If you don't install the Nvidia drivers Ubuntu
  just uses the Intel graphics, and everything works fine.

  The bug: when you install Ubuntu on a PC with Nvidia Optimus, jockey
  recommends you install the (non-working) Nvidia drivers.

  Solution: detect Optimus and only recommend the Nvidia drivers when
  it's not present.

  Tested on Ubuntu 10.10 final.
