I found in changelog this: https://docs.mesa3d.org/relnotes/24.3.0.html Adam Jackson (8): meson: Introduce the legacy-x11 option glx: Move DRI2 client support behind legacy-x11 egl/x11: Move DRI2 client support behind legacy-x11 gallium/video: Move DRI2 support behind legacy-x11 ... Seems, the new Mesa compiled without option 'legacy-x11' - since ver 24.3.0 Mesa don't depend on libxcb-dri2-0.
