Thanks for your explanations regarding the installation of a kernel "double core" on SparkyLinx: sudo apt-get install linux-headers-686-pae linux-image-686-pae. But one thing you forgot to tell us is which kernel did you get or choose ?
Looks like this kernel seems to be working o.k.: linux-3.16-2-686-pae. An answer or confirmation would be highly appreciated.
Thanks in advance.
