I am a Sparky Ultra Openbox user who connected a Logitech Trackball (a stationary mouse) after my mousepad kept falling of the desk due to lack of space.
Since the thumb controls the trackball and cursor, I always accelerate it all I can. But I haven't found a driver installed to adjust that.
However, I am sure that a solution for this will suggested to me shortly.
Thanks in advance for the orientation.
Next, I opened Syntapic to see what was installed and what wasn't but could be.
Then I tried a few things. One of them: "lxinput" (which was already installed), did the job.
