Ubuntu – Correct nvidia+intel graphics setup in 14.04

14.04bumblebeegraphicsnvidianvidia-optimus

Just upgraded to 14.04 to try to fix some other issues. Now, something has gone wrong with my graphics.

I have a Thinkpad T530 with Intel and Nvidia graphics cards.

$ inxi -SGx
System:    Host: xyz Kernel: 3.13.0-24-generic x86_64 (64 bit, gcc: 4.8.2) Desktop: N/A Distro: Ubuntu 14.04 trusty

I'm not sure what I did but now something is wrong with my graphics, as should be visible from the above commands. nvidia-detector says "none" as well.

I used to have bumblebee but then some website said to remove it and now something's clearly wrong. What's the right way to set things up? Should I try to add bumblebee back?

Here's what's installed now:

$ dpkg --get-selections | grep nvidia
nvidia-319                  install
nvidia-331                  install
nvidia-libopencl1-331               install
nvidia-opencl-icd-331               install
nvidia-prime                    install
nvidia-settings                 install
nvidia-settings-319             install

Best Answer

Before you proceed with the following please consider removing other nvidia drivers that might conflict.

For the latest proprietary Nvidia driver the following commands may be issued :

sudo apt-add-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install nvidia-current nvidia-settings

For Nvidia Optimus technology (Nvidia+Intel) and the benefit of Bumblebee features the following must be issued :

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

A final tip is to remember using optirun command in prefix of the 3D software command 

optirun somegame-or-command

You can also test 3D with the following commands

glxspheres 
optirun glxspheres
