[meta-freescale] X11 is not working on IMX.6

Dear Andre,

When I run gesture demo, I get the following console output now;

root at imx6qsabrelite:~/gpu_samp/bin# ./gesture

Using: min: 15, max: 40, val: -1

Yellow: ./gesture 15 40 -1
Skin: ./gesture 5 30 20

Loading netweights...OK

Insufficient buffer memory on /dev/video0 -- decreaseing buffers
Insufficient buffer memory on /dev/video0 -- decreaseing buffers
Insufficient buffer memory on /dev/video0 -- decreaseing buffers
Insufficient buffer memory on /dev/video0 -- decreaseing buffers
Initializing OpenCV...OK
Initializing OGLES2...OK
Creating the Stage...OK
Creating the Theater...OK
Creating the Status Panel...OKError: Resource not found.
Error: Resource not found.

Control Disabled

Now, the application is running, but I can only see black screen on the
monitor. There is an error message as seen above, but I didn't have time to
check from the software. Do you have an idea about the error message?

I have one more question: Actually I am not interested in OpenGL, because
we want to perform image processing. So, OpenCL will be more suitable for
us, but I couldn't find any examples other than hello world for IMX.6. I
searched if we can use OpenCV OCL module on IMX.6, but I learned that it is
not possible. So, if you know a way to use GPU for image processing, please
recommend a way to me (such as an example using both OpenCV and OpenCL)

Thanks&Best Regards,
Fikret
