imx6: Running X11 with hardware accleration using 12.04.01 gpu-viv- and xserver-xorg-video libs

[AbhijitPotnis]

I am facing difficulties geting X11 up on imx6 with the 12.04.01 release.

I tried building the xserver-xorg-video-imx against my X. The X when launched is very unstable and does crash pretty often. More problems arise when I try running simple OpenGLES applications.

The sample OpenGLES application crashes with a segmentation fault when trying to call eglGetDisplay().

Can any one point me to a how to doc showing how to get X11 running on imx6 with hardware acceleration.

PS: Yes, I have also loaded the galcore.ko kernel module before starting GLES app.

Regards,

Abhijit
