Enable Nvidia Optimus with Ubuntu 12.10Nvidia Optimus is a software/hardware solution that automatically switches between a low end graphics card and a high-end Nvidia graphics card based on demand. This solution allows laptops with longer battery run time. Because this solution utilizes both software and hardware, the correct software is necessary for any given operating system. Nvidia provides the software for Windows 7 and Windows 8. No official software exists for Ubuntu and other Linux distributions. The good news is that the Bumblebee project aims to provide high quality integration between Linux and Nvidia Optimus. It means they will provide the software solution that is missing on Ubuntu. It's really quite easy to install. But the Bumblebee project has some missing information on its installation page. So, here are the five simple commands to install it on Ubuntu 12.10 (you must execute them in the Terminal):
Once you completed the installation, you can use "glxspheres" (which is installed along with Bumblebee) to test the installation. You can also get some performance data with it. To run glxspheres with the low-end graphics card, simply type "glxspheres" in the Terminal. To run glxspheres with the high-end Nvidia graphics card, use the "optirun glxspheres" command. Remember, whenever you want to use the high-end Nvidia graphics card on your notebook command, you must issue the command with "optirun" in front. Jake The following are performance data that I pulled off my Asus G46VW-BSI5N06 gaming ultrabook after enabling Bumblebee: Intel HD 4000Polygons in scene: 62464 Nvidia GTX 660MPolygons in scene: 62464 Note: I installed and ran these numbers over VNC. Not sure if VNC has any impact on the numbers. But you can clearly see that the high-end graphics card blew the low-end graphics card out of the water. Jake Looks like running glxspheres through VNC makes a huge difference. Running it directly on the laptop monitor, without going through VNC provides a huge improvement: Intel HD 4000Polygons in scene: 62464 Nvidia GTX 660MPolygons in scene: 62464 Jake
