This is an interactive tool, the +user must move a finger around the touchpad, attempting to trigger an +event at all edges of the touchpad. +.PP +To terminate the event collection and print a summary, press Ctrl+C. It is +recommended that the tool is run several times to guarantee a reliable +result. +.SH OPTIONS +.TP 8 +.I WxH +The width and height of the touchpad in mm. For a touchpad 100mm wide and +75mm high, the argument is thus \fI100x75\fR. This is a required argument. +.TP 8 +.I /dev/input/eventX +The event node of the touchpad to read events from. A list of possible event +nodes can be obtained with either one of the following commands: \fBlibinput +record\fR, \fBevemu-record\fR, or \fBevtest\fR. Alternatively the event node +for a device is listed in the \fBHandlers=\fR line \fI/proc/bus/input/devices\fR. +This is a required argument. +.TP 8 +.B --help +Print a short help description +.SH NOTES +.PP +On completion, this tool prints a summary of the collected events and a +suggested udev rule. Due to rounding errors it is rare to get an exact match +for the touchpad's dimensions, but any discrepancy of more than 5mm should +be corrected with the suggested udev rule. +.PP +The udev rule should be simplified and submitted as a pull request to the +system repository at \fIhttps://github.com/systemd/systemd\fR. For further +guidance, see the file \fI/usr/lib/udev/hwdb.d/60-evdev.hwdb\fR. +.SH SEE ALSO +udev(7) |
