The thing is ugrading Ubuntu 18.04 disables my GPU hardware acceleration. glxinfo_before_upgrade OpenGL vendor string: X.Org OpenGL renderer string: Radeon RX 560 Series (POLARIS11 / DRM 3.23.0 / 4.15.0-10-generic, LLVM 5.0.1) OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.3.3 glxinfo_after_upgrade OpenGL vendor string: VMware, Inc. OpenGL renderer string: llvmpipe (LLVM 5.0, 256 bits) OpenGL core profile version string: 3.3 (Core Profile) Mesa 17.3.3 This problem is reproducible. Steps to reproduce: 1. Install Ubuntu 18.04 daily live. I've tried Kubuntu 18.04 Feb 26's daily live(the installer in Mar 1 crashes which prevents me from installing it) and Xubuntu 18.04 Mar 2's daily live. Ubuntu is utilizing my GPU in live cd session and after the fresh install Ubuntu is also utilizing my GPU. 2. Reboot into the newly installed system, do a dist-upgrade and reboot again. Opengl renderer falls back to llvmpipe.
