SimpleGLScreen issue

[otemeshen]

Running hellogl_es2 on imx53 board:

./hellogl_es2 -display simplegl:rgb16 -qws

I am getting the following issue:

SimpleGLScreen: could not create the full-screen window

SimpleGLScreen: may need to modify defaultRootWindowHandle()

simplegl: driver cannot connect

Aborted

The current implementation of simplegl assumes that the native window id is zero. Has this changed?  Has anyone observed this behavior?

[otemeshen]

Application note: AN3994 says the native window id should be the file descriptor returned from open("/dev/fb0").  But this has not worked on my platform.

eglCreateWindowSurface

                            (context->display(), context->config(),

                             open("/dev/fb0", O_RDWR, NULL), props.properties());

Patch based on L2.6.35_11_09_ER_SOURCE, to provide: GPU driver update.
