ts_calibrate is a graphical tool to calibrate the touch sensor. The app asks the user to tap a sequence of 5 cross-hairs with a stylus. It recalibrates the touchscreen, then exits.
It is a C program, ts_calibrate.c, and appears to be part of the xcalibrate package.
- I am not sure where the upstream sources of this come from. Could someone add that please? It appears to be also distributed by OpenEmbedded and GPE. --Dcorking 18:37, 20 August 2007 (CEST)
You probably won't get good results with a finger or fingernail - so try to have a stylus handy.
