<div dir="ltr"> Hi, we finally found the problem: x11-server was compiled without glamor driver. Before we enabled glamor we have only software rendering on x11, but checking mesa3d documentation: to use OpenGL with Lima driver and x11 there is needed modesetting & glamor drivers (the last one where missed by a libepoxy library dependency) Then the message "libEGL warning: DRI2: failed to authenticate" no longer appears... but now all OpenGL apps crash (with a "Segmentation fault") We checked the /tmp/Xorg.0.log file and found only one error message: ... (EE) AIGLX error: sun4i-drm does not export required DRI extension (II) IGLX: Loaded and initialized swrast ... The solution was found thanks to the following post, short story: the xserver doesn't recognize drivers with hyphen in the name (sun4i-drm), we use xorg version 1.20.9 and have found there is needed a patch (located in the post) "<a href="https://forum.clockworkpi.com/t/apt-full-upgrade-getting-the-new-software-updates-from-debian/5664">https://forum.clockworkpi.com/t/apt-full-upgrade-getting-the-new-software-updates-from-debian/5664</a>" Once we aplied the patch there are no more error messages on Xorg.0.log ... (II) AIGLX: Loaded and initialized sun4i-drm (II) GLX: Initialized DRI2 GL provider for screen 0 ... All seems to be fine, but OpenGL apps still crash. If we use kmscube test (after killing xorg server to permit the access) the app works fine (60fps) We will keep on searching for a solution. Any help or clue would be greatly appreciated. Thanks for your help and time!
