Created attachment 137150 [details] 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: [ 6.245] (EE) AMDGPU(0): eglGetDisplay() failed [ 6.245] (EE) AMDGPU(0): glamor detected, failed to initialize EGL.

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. http://metadata.ftp-master.debian.org/changelogs/main/libg/libglvnd/libglvnd_1.0.0-2_changelog -- Timo Aaltonen <firstname.lastname@example.org> Fri, 26 Jan 2018 13:48:45 +0200 -- Timo Aaltonen <email@example.com> Sat, 03 Dec 2016 02:09:57 +0200

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. https://packages.debian.org/experimental/libegl-mesa0

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...
