The POP OS no longer utilizes my GPU following the update.
The POP OS no longer utilizes my GPU following the update.
Hi... I’ve been running PopOS 20.04 since its release via the OIBAF ppa on a R9 290. It worked smoothly with the Radeon API until two days ago when PopShop released an update. After applying it, my system became slow and laggy. I checked the sys details and saw it was using the LLVM 10.0.1 API. That confused me—why would an update break my OS? I’m new to Linux and only thought about reinstalling drivers, but that didn’t help. Now I’m stuck with the same issue. A recent Reddit video (link below) shows what happened and might offer a solution.

Let me know if you need further help!
I don't have any hardware specifications. Would you like me to suggest a rollback option instead?
During deeper checks, I discovered the "grub" was configured with the default "Quiet splash." I applied the command host +si:localuser:root; sudo gedit /etc/default/grub and modified the grub settings accordingly. Updated the line to include your preferences: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.si_support=1 radeon.cik_support=1 amdgpu.si_support=0 amdgpu.cik_support=0" (noting I don’t use an AMD GPU). After saving, exiting and running sudo update-grub brought a reboot. However, it still gets stuck on llvmpipe (LLVM 10.0.1, 256 bits). I’m running out of options except to reinstall from the beginning.
I managed to resolve my own problem once. I’m not sure if it was my mistake or the update, but it worked. I checked with dpkg -l | grep -i amdgpu and saw ROCm listed, so I purged the related packages and removed the PPA manually before rebooting. It was a relief when AMD® Hawaii appeared again—Phew! The main issue was that the ROCm PPA remained in my repository even after I removed it through the AMD Wiki, despite working fine until the latest update. Overall, I’m glad I fixed it myself, though I still don’t fully understand why it happened initially. If you’re curious about why I had the ROCm drivers installed, I own a R9 290 and was trying to enable AMDGPU for OpenGL 4.5. Many guides suggested using amdgpu-pro, but none of them succeeded until now. Now I’m also running Windows 10 for three games that need Vulkan support. I’m really proud of myself—no more total beginner!
AMDGPU offers practical help for Sea Islands (cik - your R9 290) provided your distribution builds the kernel with support turned on. Uncertain if it functions on PopOS, but worth a shot. https://wiki.archlinux.org/index.php/AMD...K)_support
HI Nayr438 .. It's been a while since we last spoke. I tried that guide but unfortunately it didn't work. It was actually the page that directed me to more information, which suggested using the amdgpu-pro API. I followed the guide without any changes. From what I've read, SI cards often have problems with the latest kernel versions. I've seen many similar posts going back to 16.04, repeating in 18.04 and now 20.04. I think it's just a matter of time before it gets fixed properly, maybe in another year or so. I recently got a spare SSD and plan to experiment with Manjaro soon—so things are never predictable!
