Phoronix reported that AMDGPU loading at boot stopped the display on its Ubuntu 26.10 test system with a Radeon RX 9070 GRE. The publication used nomodeset to get the display working, but the card fell back to LLVMpipe, so Phoronix omitted graphics tests. The account was published on October 28, 2026; it describes a test on an AMD Ryzen 9 9900X3D2 system.
What happened during the Ubuntu 26.10 test
Phoronix said the display failure occurred when AMDGPU loaded at boot and described the behavior as a regression compared with Ubuntu 26.04 LTS on that same system.
The test setup paired an AMD Ryzen 9 9900X3D2 processor with a Radeon RX 9070 GRE. The reported result is specific to that configuration.
Why the run produced no graphics comparison
Phoronix used nomodeset to bring the display back. The Radeon then fell back to LLVMpipe, a software renderer, and the publication left out graphics benchmarks. As a result, this run offers no GPU-performance comparison among the distributions.
