Hi,
I think gl_FragData doesn't support integer output.
Try using OpenGL 3.3 core syntax :
In the fragment shader :
Code:
layout(location=0) uivec2 myIntegerOut;
main()
{
myIntegerOut = uivec2(128,534);
}
"layout" qualifiers are really usefull, and seems to be the better way to
configure all inputs and outputs of each shader stage, have a look here :

Cheers,
Aurelien
