ZTSSCALE(8)        OpenBSD System Manager's Manual (Zaurus)        ZTSSCALE(8)

NAME
     ztsscale - Zaurus touch screen calibration tool

SYNOPSIS
     ztsscale

DESCRIPTION
     The Zaurus lcd(4) screen and zts(4) touch point scanning logic is poorly
     aligned and requires calibration.  ztsscale is used interactively (and at
     installation time) to calculate both the scaling and offset values which
     will make the pointer act at the indicated location on the screen.

     When run as root from the raw console, ztsscale temporarily takes over
     the Zaurus wsdisplay(4) attached to the lcd(4), and prompts for five
     crosshairs to be touched.

     When good deviations are calculated from the selections made at these
     points, ztsscale will exit and provide on standard output a result like
     the following:

           mouse.scale=200,3400,312,3672,0,640,480

     This result should be placed into /etc/wsconsctl.conf for future use, or
     can be immediately applied using:

           # wsconsctl mouse.scale=200,3400,312,3672,0,640,480
