+Subject: [PATCH] Wayland-drm: Fix not finding wl_drm_interface on systems with
+ libglvnd
+
+We do not want just any libEGL.so.1 we want mesa's libEGL.so.1 as that
+is the only way which defines the wl_drm_interface symbol we need,
+one systems with libglvnd libEGL.so.1 is a dispatcher library provided
+by libglvnd and the actual mesa libEGL we want is named libEGL_mesa.so.0
+so try that first.
