Hi Adrian!
Right now, I have configured what Adrian suggested in a mail a couple of months ago:You need to add this line: deb [arch=all] http://ftp.debian.org/debian/ unstable contrib non-free
thank you for the prompt response! That was all it was needed, the detail of "arch=all".
Now acceleration starts and is used, I have other issues, but about that a different story, I will post details
I acceleration is disabled, do you know what OpenGL drops back to? Mesa? there must be an endianess issue, I thing an AGBR/RGBA issue because everything shows with a "blue veil" (I test WebGL samples inside ArcticFox a the moment)
Einen guten Rutsch ins Neue Jahr!
(Happy new year)
Riccardo
