any hint for sorting out that problem apparently related to the nvidia graphic card it is in use in my laptop?

thanks

You can pretty much ignore it if you don't want to use the Nvidia card at all. If you do, I've only had experience using Bumblebee to switch the 3D rendering to the Nvidia card using the non-free Nvidia driver, not nouveau.

thanks

I had a quick look at the documentation and decided, as you suggested, to ignore it by leaving everything as it is (for now, at least)

anyway, good to know something more specific about this issue, in case of any future problems will come up

I'll eventually give a go to bumblebee optimus (just in case)

best
