I was booting up, I had the trackball connected to the USB port (that
has the power connector next to it) and while it was loading the
greeter (? the login window) the trackball did work. Then once the
login window came up, that was it.
I'm kinda stumped here...
sometimes some USB devices don't like other things plugged in that same
bus.. as in only have the trackball plugged in, and the other port
spare.. maybe not enough power.. I had that same issue recently with the
trinity DM, the mouse didn't work. I... gave up:) went back to MATE.
does it work on say the XFCE desktop manager?
