View graphics card and GPU information in CentOS

Lspci | grep-ivga can display the graphics card information on the machine, such as [root @ localhostconf] # lspci | grep-ivga01: 00.0 VGAcompatiblecontroller: nvidiaconfigurationdevice1081 (reva1). 0 VGAco

Lspci | grep-I vga

This will display the graphics card information on the machine, such

[Root @ localhost conf] # lspci | grep-I vga
. 0 VGA compatible controller: nVidia Corporation Device 1081 (rev a1)
. 0 VGA compatible controller: nVidia Corporation GT215 [GeForce GT 240] (rev a2)
08:05. 0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 10)

 

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

[Root @ localhost conf] # lspci-v-s 02: 00. 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.

We can see that there is also a video card that is GTX 570, and the video memory is 1279 M, that is, the. 0 we see with lspci.
