Title: Touchscreen without driver!!!
Post by: vinnie on October 08, 2011, 07:13:41 PM

Few minutes ago i press my screen for error, and the mouse select and move on the screen!
the only problem is that the mouse is not calibrated and its position not correspond  to position of the pression.

I have a eepc touch with xorg 7.5 and tinycore 4.1, where did this magic, from new kernel? I remember with 3.x without driver only the pressure is detected but not moving.
does anyone know how I could calibrate it?

To build I needed autoconf autogen automake (By the way, there is a metapackage which installs them all?) and xorg dev.
The good news is that it automatically installs in /usr/local/...
The bad news is that it doesn't detect my device:

Code: [Select]

tc@box:/$ xinput_calibrator
Error: No calibratable devices found.
tc@box:/$ xinput_calibrator --list
No calibratable devices found.
tc@box:/$

this is --help

Code: [Select]

tc@box:/$ xinput_calibrator --help
xinput_calibratior, v0.7.5

Usage: xinput_calibrator [-h|--help] [-v|--verbose] [--list] [--device <device name or id>] [--precalib <minx> <maxx> <miny> <maxy>] [--misclick <nr of pixels>] [--output-type <auto|xorg.conf.d|hal|xinput>] [--fake]
-h, --help: print this help message
-v, --verbose: print debug messages during the process
--list: list calibratable input devices and quit
--device <device name or id>: select a specific device to calibrate
--precalib: manually provide the current calibration setting (eg. the values in xorg.conf)
--misclick: set the misclick threshold (0=off, default: 15 pixels)
--output-type <auto|xorg.conf.d|hal|xinput>: type of config to ouput (auto=automatically detect, default: auto)
--fake: emulate a fake device (for testing purposes)
tc@box:/$

any idea?

Perhaps you need to set the touchscreen to evdev in Xorg instead of mouse?

unfortunately I can not understand what I must do.
I'm doing research but I understand too little, I think I will postpone the solution... for posterity  :o
