1- install sysinfo :

sudo apt-get install sysinfo

and then run it -->

sysinfo

2- Alternatively use :

sudo lshw -businfo | grep -i display

find your exact graphic card model and check the manufacturer website

3- there are other command as well like :

sudo apt-get install hardinfo

enter image description here

Hope that works ;)

    hardinfo is incapable of showing GPU VRAM. Where on your screenshot is total amount of VRAM displayed?? Commented Nov 3, 2016 at 13:49

Step 1. lspci | grep VGA Note down the numbers at the beginning of the output line. E.g 00:02.0

Just for information: this number provides the domain, bus, slot and function parameter for your graphics card [[[[<domain>]:]<bus>]:][<slot>][.[<func>]]

Step 2. Insert the above number after -s parameter So if the number was 00:02.0 then the command will be lspci -v -s 00:02.0

The following steps worked for me:- (Ubuntu 22.04 LTS)

  1. Use command lspci | grep VGA to find graphics card. You will get something like this 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b).
  2. Kindly focus on the 00:02.0 part, it might be different for you. Then use this command lspci -v -s 00:02.0. Use your own pattern in place of mine.
  3. Then you will get all information related to that graphics card like this My Screenshot of the result
