I have installed Ubuntu 12.04.2 on my system (Dell XPS L702x). My system has nvidia optimus and I am not able to install optimus in order to avoid loud fan and other things like very short battery life.

I ran lspci -vmk | grep -A 8 -B 2 VGA in order to see what drivers are used for the hardware, the result of the command is the following:

Device: 00:02.0
Class:  VGA compatible controller
Vendor: Intel Corporation
Device: 2nd Generation Core Processor Family Integrated Graphics Controller
SVendor:    Dell
SDevice:    Device 0571
Rev:    09
Driver: i915
Module: i915

Device: 01:00.0
Class:  VGA compatible controller
Vendor: NVIDIA Corporation
Device: Device 124d
SVendor:    Dell
SDevice:    Device 0571
Rev:    a1
Driver: nvidia
Module: nvidia_current_updates
Module: nouveau

I have followed the instruction at Ubuntu Help Wiki to install optimus but when I run sudo apt-get install bumblebee bumblebee-nvidia linux-headers-generic-lts-quantal, I get the following error message:

The following packages have unmet dependencies:
 bumblebee-nvidia : Depends: nvidia-current but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

After following the instruction at Is a NVIDIA GeForce with Optimus Technology supported by Ubuntu? the issue seemed to be solved, but now I am continuously getting Internal error, by the error report system I was able to get the following information: ExecutablePath - /usr/share/apport/apport-gpu-error-intel.py Package - xserver-xorg-video-intel (not installed) ProblemType - Crash etc...

Do I have to install xserver-xorg-vido-intel ? Can you please help me? thank you!

follows the new output of lspci -vmk | grep -A 8 -B 2 VGA

  • How specifically did you try to resolve the unmet dependencies, such that it "lead [you] to being unable to run [your] system"? And what do you mean by that, exactly? If you can provide more information, this can be reopened; right now, you have not yet explained how and why the solutions there didn't work. As for whether or not Bumblebee works on Precise, maybe How well do laptops with Nvidia Optimus work? will help. – Eliah Kagan Apr 03 '13 at 21:49
