I just bought a new laptop (LAPTOP DELL INSPIRON 5558 15.6'' INTEL CORE I3-4005U 4GB 500GB NVIDIA GT920M 2GB FREE DOS). Since I am familiar with windows and have no idea of Ubuntu 14.04 lts I tried to learn them. My problem is that although I use the following command (lspci -vnn | grep -i VGA -A 12) on terminal, it does not show me the name of the card. What do I have to do??? Also any good advise to begin studying about Ubuntu and understanding some things will be helpful. Thanks

First install the NVIDIA drivers.
Open a terminal and execute : 

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

Now see graphics information.
Open a terminal and execute : 

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

Update - addressing your comment that you did not install drivers but NVIDIA X Server Settings :

To make sure that you will have a clean and properly working graphics drivers installation on the laptop, uninstall every currently and maybe only partly installed NVIDIA drivers related software.

Open a terminal and execute : 

sudo apt-get purge nvidia*  
sudo reboot

Install NVIDIA drivers and Optimus.

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

Now the output should read like this : 

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

  • I have not yet install the drivers. I tried to see my graphics information and that's what I see on my terminal screen: 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b) Subsystem: Dell Device 06ad Kernel driver in use: i915 -- 08:00.0 3D controller: NVIDIA Corporation Device 1299 (rev ff) Also nvidia x server settings is already installed, does that mean that the drivers are installed too? – spiros Jan 29 '16 at 15:12

  • To know your graphic card details :

Open a terminal Ctrl+alt+T and run this command:

`lspci -vnn | grep -i 3D -A 12`

To install the NVIDIA drivers run this command:

sudo apt-get update  
sudo apt-get install nvidia-352
  • Now reboot your laptop with sudo reboot (or normal GUI method)
  • As you asked, To learn about Ubuntu, I suggest you once Visit Official Ubuntu Documentation and Ubuntu Guide where you can learn lot of things about Ubuntu.
