How to Install AMD Drivers on CentOS Stream 9 – Step by step

Verifying Driver Availability

2. 2. Verifying AMDGPU Driver Availability

   The AMDGPU driver is included in the Linux kernel and should be available on CentOS 9 by default. To verify if the driver is loaded:

   lsmod | grep amdgpu

   If the command returns output, the AMDGPU driver is already loaded. If there is no output, you can manually load the driver:

   sudo modprobe amdgpu

   To ensure the driver loads automatically at boot, add it to the list of modules to be loaded:

   echo "amdgpu" | sudo tee -a /etc/modules-load.d/amdgpu.conf

   Then, reboot your system:

   sudo reboot

3. 3. Confirming AMDGPU Driver Operation

   After rebooting, confirm that the AMDGPU driver is active:

   lsmod | grep amdgpu

   You can also check the X server log to ensure the driver is being used:

   cat /var/log/Xorg.0.log | grep amdgpu

   Additionally, to check the GPU’s status and utilization, you can use:

   glxinfo | grep "OpenGL renderer"

   If the output mentions your AMD GPU, the driver is functioning correctly.

Now, your CentOS 9 system should be utilizing the open-source AMDGPU driver for your AMD Radeon graphics card.
