XTSSCALE(1) OpenBSD Reference Manual XTSSCALE(1)NAMExtsscale - X touch screen calibration tool
SYNOPSISxtsscale [-D display] [-d device] [-o output] [-v]
DESCRIPTIONxtsscale is used interactively to calculate both the scaling and offset
values which will make the pointer act at the indicated location on the
screen.
The following options can be used:
-D display
specify the X11 display to use.
-d device
defines the name or numerical identifier of the X Input extension
device to calibrate. Use
$ xinput --list
to figure out the actual name for the X configuration. device
can be omitted if there is only one X extension pointer in the
system.
-o output
specifies the XRandR output to with the touch screen is
connected. If omitted xtsscale will use all heads in multi-head
configurations, which is probably not what is expected. Use
$ xrandr
to figure out the names of the outputs.
-v specifies that xtsscale will be verbose, outputting the raw
coordinate values produced, mostly for debugging purposes.
When good deviations are calculated from the selections made at these
points, xtsscale will exit and provide on standard output a result like
the following:
mouse.scale=200,3400,312,3672,0,1024,768
This result should be placed into /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.
NOTES
To use xtsscale the mode of the raw mode of the input device should be
set in the /etc/X11/xorg.conf X configuration file. See ws(4) for
details.
/etc/wsconsctl.conf cannot currently be used to set the calibration data
of a device that is not the first device. ( /dev/wsmouse0)
