Check for GPU on CentOS Linux

Try lshw or lspci. They have to be installed if you don’t have already.

Install lshw

sudo yum install lshw //CentOS
sudo apt-get install lshw // Ubuntu

Then run this

sudo lshw -C display

The output would look like this

 *-display

Similarly, you can try lspci

lspci | grep VGA
