It is attached to the hardware specific drivers and provides a character device interface which returns .Fa struct wscons_event via .Xr read 2 . For use with X servers, .Dq mouse events or .Dq touch events can be generated. .Pp The .Nm driver provides a number of ioctl functions to control various parameters (see .Pa /usr/include/dev/wscons/wsconsio.h ) . The .Xr wsconsctl 8 utility gives access to these variables. .Pp Touchpad input is processed in one of two modes: In .Dq absolute mode , the .Nm driver generates touch events. Absolute mode is activated by .Xr synaptics 4 . In .Dq compatibility mode , which is the default, .Nm converts the input internally and generates mouse events. .Xr wsconsctl 8 can query and set several configuration parameters for this mode. The composite field names have the form .Cm mouse Ns Oo Ar N Oc . Ns Cm tp . Ns Ar field where .Ar N is the index of the .Nm device. If .Ar N is omitted, commands apply to .Pa /dev/wsmouse0 . .Bl -tag -width Ds .It Cm mouse.tp.tapping Setting this parameter to a non-zero value enables tap gestures. Contacts on the touchpad that are immediately released again trigger click events. One-finger, two-finger, and three-finger taps generate left-button, right-button, and middle-button clicks, respectively. If, within a short time interval, a second touch follows a one-finger tap, the button-up event is not issued until that touch ends .Pq Dq tap-and-drag . .It Cm mouse.tp.scaling The value is a scale coefficient that is applied to the relative coordinates. It determines the base speed of the pointer. .It Cm mouse.tp.swapsides If this parameter has a non-zero value, the order of software button areas is inverted. If edge scrolling is enabled, the scroll area is set up at the left edge of the touchpad. .It Cm mouse.tp.disable A non-zero value disables pointer movement, tapping, and scrolling. Software buttons (and external physical buttons) will work as usual. .It Cm mouse.tp.edges This field contains a list of four values that define the relative sizes of the edge areas, in the order: .Bd -literal -offset indent .Sm off .Ar top , right , bottom , left .Sm on .Ed .Pp The unit is percent of the total height of the touchpad surface, or of its total width, respectively. In order to mitigate the effects of accidental touches, the driver ignores most types of input from an edge area (see below). If an edge area contains software buttons, they fill up the space provided. .El .Pp The automatic configuration enables two-finger scrolling and sets up edge areas at the vertical edges. On clickpads - where the device surface serves as a single, large button - it provides three software button areas at the bottom edge, for left-button, middle-button, and right-button clicks. On some laptops with a trackpoint, the software buttons are at the top edge. Vertical edge scrolling will be enabled on older touchpads that do not report contact counts. .Pp A touch that starts and remains in an edge area does not trigger pointer movement. At the vertical edges and the top edge, tapping and two-finger scrolling require that at least one touch is in the main area of the touchpad (the exact behaviour of a single-touch device depends on its firmware in this case). When multi-touch input is available, a touch is ignored if it rests in the bottom area while there are other inputs - movement, scrolling, or tapping -, and the driver continues to ignore it as long as and whenever other touches are present. .Sh FILES .Bl -tag -width /usr/include/dev/wscons/wsconsio.h -compact .It Pa /dev/wsmouse* .It Pa /usr/include/dev/wscons/wsconsio.h .El .Sh SEE ALSO .Xr ams 4 , .Xr hilms 4 , .Xr intro 4 , .Xr lms 4 , .Xr mms 4 , .Xr pms 4 , .Xr ubcmtp 4 , .Xr ums 4 , .Xr utpms 4 , .Xr wscons 4 , .Xr wsmux 4 , .Xr wsconsctl 8 , .Xr wsmoused 8
