I also have a Synaptics touchpad which used to have plenty of similar problems before, so that when I would boot NetBSD on it I would always attach a mouse. Recently in -current there were two sets of changes, in driver level and in X, which made it rather usable for me; one still has to be careful, but it is much better than before. One has to use -current, though. > > hw.synaptics.up_down_emulation = 3 > hw.synaptics.up_down_motion_delta = 1 > hw.synaptics.gesture_move = 200 > hw.synaptics.gesture_length = 20 > hw.synaptics.edge_left = 1632 > hw.synaptics.edge_right = 5312 > hw.synaptics.edge_top = 4288 > hw.synaptics.edge_bottom = 1568 > hw.synaptics.edge_motion_delta = 32 > hw.synaptics.finger_high = 35 > hw.synaptics.finger_low = 20 > hw.synaptics.two_fingers_emulation = 0 > hw.synaptics.scale_x = 16 > hw.synaptics.scale_y = 16 > hw.synaptics.scale_z = 32 > hw.synaptics.max_speed_x = 32 > hw.synaptics.max_speed_y = 32 > hw.synaptics.max_speed_z = 2 > hw.synaptics.movement_threshold = 4 > hw.synaptics.movement_enable = 1 > hw.synaptics.button_boundary = 2288 > hw.synaptics.button2_edge = 2858 > hw.synaptics.button3_edge = 4085 > hw.synaptics.finger_scroll-min = 13 > hw.synaptics.finger_scroll-max = 14 > hw.synaptics.finger_scroll-hysteresis = 30 > hw.synaptics.aux_mid_button_scroll = 1 > > I have not seen somee specific setting, but maybe the button > boundaris/edges control this behavioiur and are detected wrong? > > Riccardo -- ----
