this is how to calibrate using ts_calibrate:
TSLIB_CALIBFILE=/etc/pointercal TSLIB_TSDEVICE=/dev/input/event0 TSLIB_CONSOLEDEVICE=none ts_calibrate
ts_calibrate doesnt take commandline arguments but reads environment
this will generate /etc/pointercal like this:
9743 -19 -3304336 -188 -11764 44979608 65536
(NO newline at the end!)
but you would have a rather old rootfs for /etc/pointercal to have any
the "modern" way to save calibration information is either via a udev
rule or with a config file in /etc/X11/xorg.conf.d/
here is my /etc/X11/xorg.conf.d/tsc2007.conf:
MatchProduct "TSC2007 Touchscreen"
Option "Calibration" "339 3524 3798 225"
it works fine with my debian testing setup.
instead of setting a config file you can also use xinput to have some
immmediate effect like this:
xinput set-int-prop "TSC2007 Touchscreen" "Evdev Axis Calibration" 32 339 3524 3798 225
maybe those settings should be documented somewhere?
