[meta-freescale] using openGL via SW

[Daiane Angolini]

I'm trying to enable openGL on a not accelerated board (imx7d).  I
thought it would be out-of-box  but it is not.

I'm using imx7dsabresd machine, and  to be sure added:


CORE_IMAGE_EXTRA_INSTALL += "mesa-demos mesa-glut glmark2"

on local.conf, and this is the only change on top of master
(core-image-x11) But when I try glmark I get an error message

$ DISPLAY=:0 glmark2
name of display: :0
Error: couldn't find RGB GLX visual or fbconfig

I get the same error if I try glxgears. But I see the X11 console on
screen (typical core-image-x11)

Am I missing something obvious?

Thanks in advance,
Daiane
