How to see available VGA/GPU/OpenGL/Displays available on our Linux Server ?

Today in this article, we will see how to check the available VGA/GPU/Graphics cards with our Linux system.

Let us have a look at different commands available to achieve this.

1. Using lspci command
We can search in lspci command the VGA cards available.

[root@ngelinux001~]# lspci |grep -i vga
02:00.0 VGA compatible controller: NVIDIA Corporation GM204GL [Quadro M4000] (rev a1)

 

2. Using nvidia-smi command if this is NVIDIA card.

[root@ngelinux001~]# nvidia-smi

[root@ngelinux001~]#  lshw -C display
