OpenGL ES under crouton/Ubuntu ARM Chromebook

Greetings,

I am trying to run sample code for Mali_OpenGL_ES_SDK_v2.4.4 on a SAMSUNG ARM Chromebook.

I was able to run examples for OpenCL SDK 1.1.0 following

     Random ideas of a drinking cat: OpenCL on the Samsung Chromebook ARM, under crouton

This leads me to believe I downloaded the proper user side mali drivers.

I set BASH shell variables:

export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib:/home/mfilmore/Mali/lib/x11

export TOOLCHAIN_ROOT=/usr/bin/

export TARGET=arm

export DISPLAY=:0.0

I followed

  Mali_OpenGL_ES_SDK_v2.4.4/docs/html/quick_start.html

to compile samples.

Samples fail to run based on unable to initialize openGL ES:

======================

(trusty)mfilmore@localhost:~/Mali/Mali_OpenGL_ES_SDK_v2.4.4/bin_arm/opengles_20/antialias$ ./antialias

No protocol specified

Error: eglGetError(): 12289 (0x3001)

Error: Failed to initialize EGL at ../../simple_framework/src/EGLRuntime.cpp:245

======================

This leads me to believe the code is having a problem initializing the display.

Can some kind person help me out here?

Thanks much,

-Mike
