After I updated Ubuntu Mate to 17.04 with linux kernel 4.10, my Dualshock 4 (PS4 controller) on which I was playing games (PPSSPP emulator) stopped working (clicking any button on controller does nothing).
I installed Mate 16.04, and Dualshock 4 was working. Later I installed Linux-image 4.10-22, and again - DS4 no reaction.
How do I play games with a DS4 on linux-image 4.10? (I need it because games are smoother on 4.10).
