Weston does not do transparent backgrounds

[arunkrish20 .]

Hi All,

http://wayland-devel.freedesktop.narkive.com/dXZUCogH/desktop-shell-how-to-enable-really-alpha-blending-of-weston-background

Our question is related to above mentioned link question.

Environment
OS : Linux kernel 3.14
Version : Weston 1.9.0

Weston fbdev-backend.

In compositor-fbdev.c
fbdev_output_create()

*called *
gl_renderer->output_create(&output->base,
                           (EGLNativeWindowType)NULL, NULL,
                           gl_renderer->*opaque_attribs*,
                           NULL, 0) < 0) {
            weston_log("gl_renderer_output_create failed.\n");

*can be changed to*
gl_renderer->output_create(&output->base,
                           (EGLNativeWindowType)NULL, NULL,
                           gl_renderer->*alpha_attribs*,
                           NULL, 0) < 0) {
            weston_log("gl_renderer_output_create failed.\n");

Is that change will give some help? I havn't tried. But in that link if we
use fbdev-backend then there is no hope to expect the alpha.

Any update or direction, Could you please suggest...


Thanks,
Arun
