This problem is still not solved. Workaround is to use ironhide (new
name of Bumblebee) or hybrid-windump. One of these programs should be
installed and used for 3d applications by default to make the use of 3d
applications possible on Multi-GPU systems.

On my system with a NVIDIA GeForce GT 540M I do not have working 3d
accelaration without ironhide or hybrid-windump. In addition, neither
the recommended NVIDIA drivers nor the original proprietary NVIDIA
drivers from NVIDIAs website work.

Title:
  Recommended drivers don't work with Nvidia Optimus

Status in NVIDIA Drivers Ubuntu:
  Confirmed
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.
