Hi almendro, thanks for your contribution. Are you sure the AMD card really works with 3D with Trisquel? I've also set the compatibility class to C-silver since only the webcam model does not work

Hi tonicucoz, I follow this procedure to test the 3D.

$ glxinfo | grep direct

that output > direct rendering: yes and late

$ glxgears

that output an animation in 3D. source: http://www.guia-ubuntu.org/index.php?title=Aceleraci%C3%B3n_Gr%C3%A1fica About the compatibility class note that bluetooth and card reader does not work yet at least for me. Best regards

the glxgears test is not a good test to verify if the 3d acceleration works or not, see here: http://www.h-node.com/issues/view/en/67. Try to enable compiz, if you can use effects then the 3d acceleration works, otherwise it doesn't work.

About compatibility level, ok to use D-bronze if also the sd card does not work.
