Ubuntu - GPU - AMD GPU - Setup Radeon RX 7900 XTX
Approach
- Update the system.
- Shutdown the system.
- Swap GPU card.
- Boot the system.
- This should work fine, since minimum support is via the kernel amdgpu.
- Optionally, purge Nvidia packages.
- Install Mesa.
NOTE:
- The NVIDIA packages can be kept, and will not cause any trouble but will just waste space.
- Mesa is the open source implementations of OpenGL and Vulkan that AMD GPU users typically use.
Install the AMD setup script
Download the .deb file from https://www.amd.com/en/support/linux-drivers.
Install the .deb file:
wget https://repo.radeon.com/amdgpu-install/22.40.5/ubuntu/focal/amdgpu-install_5.4.50405-1_all.deb sudo apt install ./amdgpu-install_5.4.50405-1_all.deb
or
dpkg -i package_file.deb
Run the amdgpu-install script:
amdgpu-install
NOTE: Run the amdgpu-install script without any arguments, should be sufficient.
Alternatively, try this:
amdgpu-install --usecase=graphics,opencl --vulkan=amdvlk --opencl=rocr
Optionally, install fresh firmware files
Grab the latest firmware from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git.
Drop these firmware files into /lib/firmware/amdgpu/ and rebuild any initramfs:
wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20230515.tar.gz tar -xf linux-firmware-20230515.tar.gz sudo cp linux-firmware-20230515/amdgpu/* /lib/firmware/amdgpu/ sudo update-initramfs -uk 'all'
NOTE: The latest firmware files should probably support these new GPUs.
Enable the AMD Kernel Module
Ensure there is no modprobe blacklist for amdgpu by running the command:
sudo rm /etc/modprobe.d/blacklist-amdgpu.conf
Optionally Purge nvidia drivers
Remove the Nvidia packages and any Nvidia related kernel arguments you might have (DRM Kernel Mode Setting or whatever).
NOTE: The Nvidia drivers will not load if there is no Nvidia card installed.
- Leaving the NVIDIA stack installed ensures that it is ready if you ever need to switch to a backup GPU in a hurry.
Optionally Install Vulkin
Install the AMD vulkan package to get vulkan support.
Install Mesa
sudo apt install mesa-utils
NOTE: Mesa is the open source implementations of OpenGL and Vulkan that AMD GPU users typically use.
Check that the GPU is being picked up
glxinfo | grep OpenGL
returns:
NOTE: This should show useful info on the GPU.
Test the GPU
glxgears -info
NOTE: This should show some gears spinning around, together with frames per second.
