I'm using a Dell XPSL502 15' and it's facing hybrid graphics problem. I'm really desperate, I don't know what to do - how should I fix this?

This problem has occurred before on other Linux variatns for me too, e.g. Blackbuntu, Bachtrack, Debian 6.0.4 Squeeze, Chackra, ...

Please help me if you solved this problem.

I am having the same laptop and running 12.04 flawlessly. turned off NVIDIA GPU and now battery life time is more than 3hr.

I will assume you have a fresh install and have not installed nvidia drivers OR ironhide.

(If you installed ironhide please do a fresh install.This will save time and frustation.)

Instruction for installing Bumblebee to turn off discrete GPU and enable only when required

  1. Type the following in terminal,

    sudo add-apt-repository ppa:bumblebee/stable then sudo apt-get update

  2. To install Bumblebee using the proprietary nvidia driver:

    sudo apt-get install bumblebee bumblebee-nvidia

  3. Run following

    sudo usermod -a -G bumblebee $USER

  4. Reboot.

If you just want to disable nvidia card, no need to learn followings

Usage Instruction :

To run a program with nvidia card, use optirun command prefixed in terminal. Like to run glxspheres with nvidia card type

optirun glxspheres

To run firefox type : optirun firefox &

Note: If you intend to run 32-bit programs like Wine and using Ubuntu 11.10 Oneiric or later, install 32-bit libraries with: sudo apt-get install virtualgl-libs:i386 libgl1-mesa-glx:i386 libc6:i386

In this line: "sudo usermod -a -G bumblebee $USER"; On $user you have to put the name of your user, not "$USER" – Carlos Soriano Sánchez May 9 '12 at 11:18
No its not required as $USER is an environment variable that returns current user.check with sudo echo $USER or echo $USER – Web-E May 9 '12 at 11:27
Oh, sorry, I fixed it because in the web page of bumblebee say that it has to be changed by your user name. – Carlos Soriano Sánchez May 9 '12 at 22:48
