Hi,
＞1) weston --tty=1 (using tty screens) Is it the right way.. I do this because I can see the logs.. Is there any way to use gdb while using weston ?? At first, you can set the environment value: WAYLAND_DEBUG=1 to observe if wayland application bind wl_shell and create wl_shell_surface. It might be sufficient. >(HTML not rendering on wl_shell) ?? Maybe. But if the caller of IVIsurfaceCreator calls it with wrong process ID, IVIsurfaceCreator can not find any wl_shell_surface. If you clearly know the process ID, I recommend you to execute IVIsurefaceCreator by hand. How to use it, see wiki. https://wiki.tizen.org/wiki/Wayland_ivi-shell BR, Nobuhiko Tanibata From: karthik karthik [mailto:[email protected]] Sent: Tuesday, July 29, 2014 2:32 PM To: Tanibata, Nobuhiko (ADITJ/SWG); [email protected] Subject: Re: Questions on weston-ivi-shell Hi, Surely will try with the debug option.. Currently I am launching weston in the following way 1) weston --tty=1 (using tty screens) Is it the right way.. I do this because I can see the logs.. Is there any way to use gdb while using weston ?? 2) From your previous input that the HTML5 might not be using wl_shell (can this be put as seperate question in the forum !!), I tried the following.. I put a few prints in the following function "controller_get_native_handle" in ivi-controller.c.. I beleive this is called from the IVISurfaceCreator while we create ivi_surface. When I checked out, the test I running doesnt even enter the wl_array_for_each loop. Does this means no surface are available (HTML not rendering on wl_shell) ?? static void controller_get_native_handle(struct wl_client *client, struct wl_resource *resource, uint32_t id_process, const char *title) { struct wl_array surfaces; ivi_shell_get_shell_surfaces(&surfaces); struct shell_surface ** surface; wl_array_for_each(surface, &surfaces) { uint32_t pid = shell_surface_get_process_id(*surface); if (pid != id_process) { continue; } if (title) { char* surface_title = shell_surface_get_title(*surface); if (strcmp(title, surface_title)) { continue; } } struct weston_surface *es = shell_surface_get_surface(*surface); if (es) { struct wl_resource *res = wl_resource_create(client, &wl_surface_interface, 1, 0); wl_resource_set_user_data(res, es); ivi_controller_send_native_handle(resource, res); } } wl_array_release(&surfaces); int32_t id_object = 0; ivi_controller_send_error( resource, id_object, IVI_CONTROLLER_OBJECT_TYPE_SURFACE, IVI_CONTROLLER_ERROR_CODE_NATIVE_HANDLE_END, ""); } 3) Meanwhile, I like to understand what the above code does ?? a) Is this api "ivi_shell_get_shell_surfaces" for ivi_shell, and not for the wl_shell.

You can observe what happens on it. If you can provide basement of snapshot and sandbox of your modification, I can try.
