Thanks a lot for your reply. Now I have to find out what "render offload target" means. I have tried "DRI_PRIME=1 glxgears" which I think is a good test for card performance and it reports 1700 FPS instead of the 60 FPS reported without the DRI_PRIME=1 so I assume that the dedicated card is indeed used. I will try with a couple of games and maybe with compiz (is the procedure useful for the whole desktop??). Nevertheless, it does not seem a very user-friendly way to make the dedicated card active and probably out of the reach of many users, which renders this card virtually non-existent for non experienced users or for those without the spirit of spending many hours googling to find it out. At least, I hope that, even if closed for invalid, my report and your answer may help other people facing the same problem and that may land in this dialogue by searching the internet. Best wishes.
