Hi Amit,
I also faced similar issue when i was working with eglx backend but for
some other platform. I believe not many people are working on eglx
backend, that's why i never got any response either here or in IRC.
The problem is clutter-x11 backend. Go inside
clutter_x11_get_stage_visual(). It returns CLUTTER_STAGE_X11
(impl)->xvisinfo, which is NULL here. I don't know whether it should be
set here by someone else or not. So, i took a look at the glx backend,
and found that there this is created using glXChooseVisual() in
clutter_stage_glx_realize().
So, i tried creating the visinfo by myself in clutter-x11 and it seems
to be working. But truly, i don't know whether it is the real fix.
My fix is as follows... the whole if block in brown color is my change.
XVisualInfo *
clutter_x11_get_stage_visual (ClutterStage *stage)
{
ClutterStageWindow *impl;
ClutterStageX11 *stage_x11;
XVisualInfo theTemplate;
XVisualInfo *xvinfo;
int numVisuals;
long mask;
g_return_val_if_fail (CLUTTER_IS_STAGE (stage), NULL);
impl = _clutter_stage_get_window (stage);
g_assert (CLUTTER_IS_STAGE_X11 (impl));
// return CLUTTER_STAGE_X11 (impl)->xvisinfo;
#if 1
if((CLUTTER_STAGE_X11 (impl)->xvisinfo)==NULL)
{
stage_x11 = CLUTTER_STAGE_X11 (impl);
theTemplate.screen = DefaultScreen (stage_x11->xdpy);
mask = VisualScreenMask;
xvinfo = XGetVisualInfo(stage_x11->xdpy, mask, &theTemplate,
&numVisuals);
stage_x11->xvisinfo=xvinfo;
return xvinfo;
}
else
return CLUTTER_STAGE_X11 (impl)->xvisinfo;
#endif
}

gtk-clutter(0.8.2) as well as latest (0.9.0) with "eglx flavour"
doesn't seem to be working for me.
It catches a SEG Fault at gtk_clutter_embed_init(), where
clutter_x11_get_stage_visual() returns NULL:
....
xvinfo = clutter_x11_get_stage_visual (CLUTTER_STAGE (priv->stage));
visual = gdk_x11_screen_lookup_visual (gdk_screen_get_default (),
xvinfo->visualid);
.....
gtk-clutter embedded stage works well for "glx flavour" though.
Is it a known issue?
What could possibly be the problem here?

Amit Pundir
