Hello Community,
I recently upgraded from Ubuntu 22.04 to 24.04 and my cycles render stopped using the GPU. This seems to be a common issue as the amdgpu-install script from the radeon package's apt source doesn't have support for noble (yet). The downloadable package direct from AMD doesn't mention 24.04 noble support yet either. I should mention that I did find that some had success with amdgpu-install but I only intend to use blender and don't game. That being said this may conflict with amdgpu-install (not sure) so YMMV. My primary use of the accelerated driver is exclusive to blender so this was initially a drag. Upon further investigation I can report that I was able to utilize my AMD Radeon 6600 though.
This may already be common knowledge, or have a well known fix, but I found only scant information in this regard.
Unfortunately during my quest to enable the GPU I did not keep good documentation, I will post what I did in the hopes someone else needing this will benefit.
AMD seems to be bringing better support for AMD GPU in the distro related to ROCm and hip. ROCm and HIP are used by blender to utilize the GPU in cycles.
My hardware/software:
Ryzen 5 3600
AMD Radeon 6600
Ubuntu 24.04
Blender 4.1
The solution for me:
sudo apt-get install libamdhip64-dev rocm-opencl-sdk rocm-core rocm-cmake rocm-smi rocm-device-libs-17 librocm-smi-dev
After the packages were installed the GPU option appeared and eventually after rebooting and fiddling with the Edit/Preferences (selecting Radeon under the HIP Tab in System). I was able to have a non-greyed out GPU selected under Render cycles settings.
To confirm that I was actually utilizing the GPU I ran System Monitor and radeontop. Before blender would peg all my AMD Ryzen cores, after the solution was implemented the load shifted over to radeontop.
Hope this helps someone.
