Using lspci
lspci -k | grep -A 3 -E "(VGA|3D)"
returns:
0c:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Device 744c (rev c8) Subsystem: Gigabyte Technology Co., Ltd Device 240e Kernel driver in use: amdgpu Kernel modules: amdgpu
NOTE: This shows that the kernel driver is amdgpu.
- This indicates an AMD GPU.
Using lshw
sudo lshw -c video
returns:
*-display description: VGA compatible controller product: Navi 31 [Radeon RX 7900 XT/7900 XTX] vendor: Advanced Micro Devices, Inc.

- This shows that the kernel driver is amdgpu.
Check the kernel modules
Determine the PCI Bus
lspci | grep -i vga
returns:
0c:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 31 [Radeon RX 7900 XT/7900 XTX] (rev c8)
NOTE: This shows the unique PCI Bus address of 0c:00.0.
Use the PCI Bus to check what kernel modules are being used
lspci -s 0c:00.0 -v
returns:
