As i had windows 10 with GeForce graphics card, I installed ubuntu 14.04 LTS uninstalling windows. Now I have an issue (i.e) when I pass this command

lspci | grep VGA

my results be like

00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)

it isn't showing my NVidia grpahics driver. I tried all the answers given in ubuntu forums and stack exchanges still i couldn't get rid off it. Need solved solutions.

  • I think what you should type is: lspci | grep 3D – Rifaz Nahiyan Mar 26 '16 at 7:35
  • Yes Mr. @RifazNahiyan . Now it shows me 09:00.0 3D controller: NVIDIA Corporation GF117M [GeForce 610M/710M/810M/820M / GT 620M/625M/630M/720M] (rev a1) does this mean I have installed my graphics driver?? – Karthik Mar 26 '16 at 9:00

Open a terminal and execute :

lspci -k | grep -EA2 'VGA|3D'  

Output shows something like :

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
Subsystem: CLEVO/KAPOK Computer Device 3501
Kernel driver in use: i915

01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 860M] (rev a2)
Subsystem: CLEVO/KAPOK Computer Device 3501
Kernel driver in use: nvidia

Now you can see all the graphics drivers currently being in use.

In case it does not show Kernel driver in use: nvidia ...

Install the NVIDIA drivers and Optimus support - execute :

sudo apt-get update
sudo apt-get install nvidia-352 nvidia-prime
sudo reboot  

Update adressing your response that you have issues with the drivers :

Step 1 : Uninstall every NVIDIA related software that is currently installed.

Highlight the Ubuntu entry in the GRUB boot menu and press the E key.
Add nouveau.modeset=0 to the end of the linux line - press F10 to boot.

On the login screen press Ctrl+Alt+F1
Enter user name and password - execute :

sudo apt-get purge nvidia*  
sudo reboot  

Step 2 : Install the latest official NVIDIA drivers that support NVIDIA 820M.

Highlight the Ubuntu entry in the GRUB boot menu and press the E key.
Add nouveau.modeset=0 to the end of the linux line - press F10 to boot.

On the login screen press Ctrl+Alt+F1
Enter user name and password - execute :

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-361 nvidia-prime
sudo reboot
  • bur mine doesn't belong to 860M, mine is 820M. Will it be compatible with nvidia-352?? – Karthik Mar 26 '16 at 9:12
  • @Karthik : This is just an example from a machine that has NVIDIA GTX 860M graphics, most important is : "Kernel driver in use: nvidia" and nvidia-352 is the drivers version which is compatible with 820M as well. :) – cl-netbox Mar 26 '16 at 9:16
  • Thanks Mr. @cl-netbox it is showing me "Kernel driver in use: nouveau" i'll install and tell you – Karthik Mar 26 '16 at 9:18
  • Mr. Cl-netbox I have a problem now after installing nvidia-352. After rebooting my screen remains totally blank even backlite is turned but CPU busy running lights are working. What could be the problem? This happened more number of times. Should i reinstall the OS again – Karthik Mar 26 '16 at 9:41
  • Ok Mr. Cl-netbox I'll be waiting – Karthik Mar 26 '16 at 9:44
