I am trying to run Anki on one of my computers running the latest update of CentOS 7. However, starting it in a terminal window shows it fails with the following messages: libEGL warning: DRI2: failed to authenticate libEGL warning: DRI2: failed to open swrast (search paths /usr/lib/x86_64-linux-gnu/dri:${ORIGIN}/dri:/usr/lib/dri) libEGL warning: GLX: glXQueryVersion failed libEGL warning: DRI2: failed to authenticate libEGL warning: DRI2: failed to open swrast (search paths /usr/lib/x86_64-linux-gnu/dri:${ORIGIN}/dri:/usr/lib/dri) libEGL warning: GLX: glXQueryVersion failed qt: QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled qt: QXcbIntegration: Cannot create platform offscreen surface, neither GLX nor EGL are enabled qt: QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled mpv not found, reverting to mplayer qt: WebEngineContext used before QtWebEngine::initialize() or OpenGL context creation failed. qt: QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled Aborted (core dumped) Anki 2.1.15-alternate comes with the QtWebEngine and I have this app running on two other computers running CentOS 7. Thus, not a general problem but probably related either to the graphics driver on this system xorg-x11-drv-ati or some configuration mismatch. It was suggested on the Anki support forum I ask in the distribution forum since they had no explanation...
