Most of the new input features are runtime-configurable. I don't know if there's a way to configure them in xorg.conf ahead of time; I'll check. But it looks something like this: atropine:~% xinput list-props "Logitech USB Optical Mouse" Device 'Logitech USB Optical Mouse': Device Enabled (91): 1 Evdev Reopen Attempts (224): 10 Evdev Axis Inversion (225): 0, 0 Evdev Axis Calibration (226): Evdev Axes Swap (227): 0 Evdev Middle Button Emulation (228): 2 Evdev Middle Button Timeout (229): 50 Evdev Wheel Emulation (230): 0 Evdev Wheel Emulation Axes (231): 0, 0, 4, 5 Evdev Wheel Emulation Inertia (232): 10 Evdev Wheel Emulation Timeout (233): 200 Evdev Wheel Emulation Button (234): 4 Evdev Drag Lock Buttons (235): 0 atropine:~% xinput get-feedbacks "Logitech USB Optical Mouse" 1 feedback class PtrFeedbackClass id=0 accelNum is 2 accelDenom is 1 threshold is 4 atropine:~% xinput set-ptr-feedback "Logitech USB Optical Mouse" 4 3 2 atropine:~% xinput get-feedbacks "Logitech USB Optical Mouse" 1 feedback class PtrFeedbackClass id=0 accelNum is 3 accelDenom is 2 threshold is 4 etc. 'xinput help' for more details. There should be a snazzy Gnome UI for this soon too, although I don't know if it'll make F11 gold. - ajax
