If you want to see the detailed information, such as GeForce GT 240, that is,. 0

We can see that the memory of GT240 is 256 MB.

However, in my system, two video cards are installed, and one card cannot be displayed. In this case, you can use the nvidia-smi command to check the nvidia graphics card, this command is also used to view the GPU.
