Does EGL implementation on imx6q support Native Window Resizing?

Hi,

Recently, I am working on a imx6q based board. The software is ubuntu_oneiric_4.0.0.tgz and L3.0.35_4.0.0_130424_images_MX6.tar.gz.

Also I did the instructions on file xserver-xorg-video-imx-viv-3.0.35-4.0.0/Instructions_to_setup_X11_acceleration_on_Ubuntu.

What our customer want is to switch the display resolution by command xrandr in X window, while not only set them in Uboot.

But after we did some modifications, the xrandr command worked well, but the OpenGL ES application will always fail with 'segmentation fault'.

According to document Khronos Native Platform Graphics Interface (EGL Version 1.4 - April 6, 2011), the EGL implementation should support Native Window Resizing if want to resize the window.

So we would like to know if the EGL implementation on imx6q support Native Window Resizing?

Actually using command xrandr to switch mode is necessary for many end-customers, as it is not so convenient for them to change the mode in Uboot“s bootargs by COM port.

So are there any X 11 driver from FreeScale or Vivante can support XRandR?

For more information about what we modified to the X driver, please see https://community.freescale.com/thread/309721

Thanks in advance.
