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:
dpkg -i package_file.deb
Run the amdgpu-install script:
amdgpu-install
NOTE: Run the amdgpu-install script without any arguments, should be sufficient.
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.
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'
Ensure there is no modprobe blacklist for amdgpu by running the command:
sudo rm /etc/modprobe.d/blacklist-amdgpu.conf
