I finally succeeded to enable 2D/3D hw accel. following your suggestion: thank you all guys (glmark2-es2 run ok).Nevertheless, looking at /var/log/Xorg.0.log I realized G2D accel. is not enabled.
If I remember right, I read somewhere that this is normal in H3 board since g2d driver is not supported.
Somebody can confirm that, please ?
