Same problem here. After upgrading my laptop from Lubuntu 16.04 to Lubuntu 18.04, there is no hardware acceleration anymore. AMD STONEY was perfectly capable of this on the older release.
glxinfo shows: OpenGL renderer string: llvmpipe (LLVM 6.0, 128 bits) /var/log/Xorg.0.log shows: [ 16.679] (EE) AMDGPU(0): eglGetDisplay() failed [ 16.679] (EE) AMDGPU(0): glamor detected, failed to initialize EGL.

Tried creating a xorg.conf and forcing DRI to 3, but no dice. LIBGL_ALWAYS_SOFTWARE is not set, there is no /etc/X11/Xsession.d/50_check_unity_support, so it's probably not bug #1767468. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1752938 Title: Upgrading Ubuntu 18.04 disables GPU hardware acceleration Status in xorg package in Ubuntu: Confirmed Bug description: I don't know which package causes this problem.

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.
