Are you able to run any OpenGL applications on EGL on X11? In the same environment you tried to run Weston on X11 in: can you post the output of es2_info from mesa-demos, and check that es2tri and es2gears_x11 work fine? I assume OpenGL apps on GLX work just fine? Mesa-demos is <a href="http://cgit.freedesktop.org/mesa/demos/">http://cgit.freedesktop.org/mesa/demos/</a> in case you don't have those test programs in your distribution. After building, you can find the test programs in src/egl/opengles2. "function is no-op" usually means that something is not using EGL properly to initialize GL, but I suppose it could also mean a broken Mesa installation. Have you ever built and installed Mesa manually, from source? Does rebuilding Weston with --with-cairo=image added to configure change anything? Your Weston under DRM (i.e. no X11) output looks fine on first glance, but I do not see any of the wl_surface.frame callbacks answered, which means either the compositor's repaint cycle is stuck or the client dies too soon. But let's do one thing at a time, and first make sure everything works under X11.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
