On Xubuntu, can you try downgrading the package xubuntu-default-settings
from version 18.04.2 to version 18.04.1? Maybe it's related to what I'm
seeing in bug #1752798
(you can find the older package here:
https://launchpad.net/ubuntu/+source/xubuntu-default-
settings/18.04.1/+build/13749132 )

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. 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.
