When you type 'NV138' into a search engine, the NVIDIA graphics card is identified immediately. OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3. OpenGL ES profile version string: OpenGL ES 3. OpenGL profile mask: compatibility profile

PenGL shading language version string: 4. OpenGL core profile context flags: (none)OpenGL core profile profile mask: core profile OpenGL core profile shading language version string: 4. This is the output from the physical computer: name of display: :1Įxtended renderer info (GLX_MESA_query_renderer):ĭevice: NV138 (0 x1d01) Version: 19. That's useful info when more than one card is installed on a computer. The '' text at the end of the first line indicates this is the 'operational' graphics card.

The card is an NVIDIA Corporation GP108, and, after a few seconds with a search engine, we found the NVIDIA tech page for that device. It gave us a lot of good information right away!

It doesn't matter! You can solve this conundrum either from the command line or through the graphical user interface (GUI).įor this article, we conducted our research on a variety of Linux distributions running in VirtualBox virtual machines. Let's assume the worst-case scenario and say the drivers for the graphics card were never installed, so you can't even look at those to get a clue. So how do you identify the graphics card in a Linux computer? To support something, you need to know what it is. The deer-in-headlights expression you receive in response speaks volumes. Hey, this might not be so bad after all! But then your short-lived flicker of hope is snuffed when you ask, 'What kind of graphics card do you have?' Still, you pitch in! You quickly determine the issue is likely a display driver issue. You're drafted to provide support for a nontechie relative or work colleague, and something tells you this isn't going to be painless. Why Do You Need to Know What GPU You Have? Need to identify the Graphics Processing Unit (GPU) in a Linux computer? Here's how you can identify the graphics card from the command line and in GNOME.
