.Sh NAME
.Nm xtsscale
.Nd X touch screen calibration tool
.Sh SYNOPSIS
.Nm xtsscale
.Bk -words
.Op Fl c
.Op Fl D Ar display
.Op Fl d Ar device
.Op Fl o Ar output
.Op Fl v
.Ek
.Sh DESCRIPTION
.Nm
is used interactively to calculate both the scaling and offset values which
will make the pointer act at the indicated location on the screen.
.Pp
The following options can be used:
.Bl -tag -width Ds
.It Fl c
keep the X cursor visible during calibration.
Useful for indirect absolute devices like tablets.
.It Fl D Ar display
specify the X11 display to use.
.It Fl d Ar device
defines the name or numerical identifier of the X Input extension device
to calibrate.
Use
.Pp
.Dl $ xinput --list
.Pp
to figure out the actual name for the X configuration.
.Ar device
can be omitted if there is only one X extension pointer with
calibration properties in the system.
.It Fl o Ar output
specifies the XRandR output to with the touch screen is connected.
If omitted
.Nm
will use all heads in multi-head configurations, which is probably
not what is expected.
Use
.Pp
.Dl $ xrandr
.Pp
to figure out the names of the outputs.
.It Fl v
specifies that
.Nm
will be verbose, outputting various information, including the
raw coordinate values produced, mostly for debugging purposes.
.El
.Pp
When good deviations are calculated from the selections made at these
points,
.Nm
will exit and provide on standard output a result like the following:
.Pp
.Dl mouse.scale=200,3400,312,3672,0,1024,768
.Pp
This result should be placed into
.Pa /etc/wsconsctl.conf
for further use.
The new calibration is automatically used by the X server.
The calibration process can be interrupted at any time using the ESC
key.
In this case the current screen calibration data will not be modified.
.Sh NOTES
To use
.Nm
the mode of the input device should be set to raw in the
.Pa /etc/X11/xorg.conf
X configuration file. See
.Xr ws 4
for details.
.Pp
.Pa /etc/wsconsctl.conf
cannot currently be used to set the calibration data of a device
that is not the first device. (
.Pa /dev/wsmouse0
)
