X touch screen calibration
xtsscale 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:
- keep the X cursor visible during calibration. Useful for indirect absolute devices like tablets.
- specify the X11 display to use.
- 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 with calibration properties in the system.
- specifies the XRandR output to with the touch screen is connected. If
xtsscalewill use all heads in multi-head configurations, which is probably not what is expected. Use
to figure out the names of the outputs.
- specifies that
xtsscalewill be verbose, outputting various information, including the raw coordinate values produced, mostly for debugging purposes.
When good deviations are calculated from the selections made at
xtsscale will exit and provide on
standard output a result like the following:
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.
xtsscale the mode of the input
device should be set to raw in the
/etc/X11/xorg.conf X configuration file. See
/etc/wsconsctl.conf cannot currently be used to set the calibration data of a device that is not the first device. ( /dev/wsmouse0 )
