CUDA 5.5 on optimus laptop with ubuntu 12.04 LTS

Install a pristine Ubunto distro (check tutorials)

Get make and gcc

4 sudo apt-get install build-essential

Check version

7 gcc –version

Check nvidia card present

8 lspci | grep -i nvidia

Stop X server

9 sudo service kdm stop

Remove current nvidia drivers

19 sudo apt-get --purge remove nvidia-current

Get xorg tools

20 sudo apt-add-repository ppa:xorg-edgers/ppa

21 sudo apt-get update

Get bumblebee

22 sudo apt-get install bumblebee-nvidia nvidia-319 nvidia-settings-319

23 sudo apt-add-repository ppa:bumblebee/stable

24 sudo apt-get update

25 sudo apt-get install bumblebee virtualgl linux-headers-generic

Remove nvidia-current which came with bumblebee

28 sudo apt-get --purge remove nvidia-current

Install nvidia-319 (automatically gave me 325 after all...)

29 sudo apt-get install nvidia-319 nividia-settings-319

Modify /etc/bumblebee/bumblebee.conf to replace “nvidia-current” with “nvidia-325”

sudo nano /etc/bumblebee/bumblebee.conf

Make changes valid

36 sudo reboot

Check success:

40 optirun nvidia-settings -c :8

41 locate xorg.conf

Install CUDA toolkit

43 sudo service kdm stop

44 cd Downloads/

45 l

Here, tell cuda NOT to install the driver

46 sudo sh cuda_5.5.22_linux_64.run

Add paths to .bashrc

48 nano .bashrc

Validate:

49 sudo reboot

Check how it works (did not install OpenGL et al., I dont use them)

50 cd NVIDIA_CUDA-5.5_Samples/

54 cd 1_Utilities/

56 cd deviceQuery

58 make

64 optirun ./deviceQuery
