Hi, I am in the process of setting this up, & the trackpad is no longer working on the Logitech K400. I changed this to a 220 wireless setup, & still no mouse. Then I plugged a logitech wired M105 mouse in. It still wouldn't work. But when I exited into the console (startx) it works. The mouse was working yesterday in piplay. ??? The wired mouse is plugged directly into the raspberry Pi.
