Xorg.0.log

In Debian testing many qt5 applications depends on the libegl1 package that is created from the libglvnd_1.0.0 sources. Original source is from Nvidia.
https://packages.debian.org/buster/libegl1

The presence of this package disables 2d and 3d hardware acceleration of the Mesa amdgpu  driver:

I am using Oibaf ppa Mesa git and this bug appeared in a couple of days. This work might have caused this bug:

Comment 1 Timo Aaltonen 2018-02-04 11:49:02 UTC 
mesa from oibaf ppa does not use libglvnd
Comment 2 fin4478 2018-02-04 18:13:17 UTC 
Debian Buster and Sid Mesa uses libglvnd, in other words  the libegl1 package. Thanks for that bomb in Debian. I did remove xorg and instaled it again, same problem with Buster and Sid, no hardware graphics acceleration. Siduction live uses Mesa 17.1.1 and there is no this bug.

Comment 3 Christian König 2018-02-04 18:24:32 UTC 
As Timo already explained the oibaf ppa doesn't support lbglvnd.

You can't blame anybody if you install packages which doesn't include the necessary support.

Installing libegl-mesa0 package from experimental repositry fixes the bug.

Just in case someone comes from Google looking for "(EE) AMDGPU(0): eglGetDisplay() failed, followed by (EE) AMDGPU(0): glamor detected, failed to initialize EGL.", "AMDGPU(0): 2D and 3D acceleration disabled" or "AMDGPU(0): Direct rendering disabled": I upgraded from Ubuntu 17.10 to 18.04, and for some reason, two nvidia packages, libnvidia-gl-390 and libnvidia-common-390, had been installed in my system. Removing those packages fixed the problem...
