well, there are several threads about calibration problems ...
but nothing in detail ...

here we go....
basic is froyo 2.2 with haret 1.4 + no "ts-calibrate" file existing on fat32 (sdcard)

in init (startup) the calibration command failed to work ...

as you can see (below) - there in the script the calibration call via:
then i can also see the message for clicking the 5 points, blabla...
(but the "white touch area" like as it is on diamond is not there ... and no time and it is jumping to next procedure in init script. the most users doesn't see that, because it does fast switch/show another lines ....)

then i see an error: (this comes from command "tssc-calibrate")
open input device: Inappropriate ioctl for device

any idea how to fix ?

for i in /sys/class/input/input* ; do
        if [ "`cat $i/name`" = "tssc-manager" ] ; then
                echo "Touchscreen device directory is $i"

if [ -f /sdcard/ts-calibration ] ; then
        echo "Using Saved Touchscreen Calibration"
	echo 128,128,1903,128,128,1907,1903,1907,1024,1024 > $touchscreendir/calibration_screen
        cat /sdcard/ts-calibration > $touchscreendir/calibration_points
        mkdir /dev/graphics
        mknod /dev/graphics/fb0 c 29 0
        echo; echo; echo; echo; echo; echo; echo; echo "Calibrating Touchscreen:"
        echo "Click the Five Targets in order -- Top Left, Top Right, Middle, Bottom Left, Bottom Right"
	echo "(Tap lightly. The screen is quite sensitive.)"
        echo 0,0,0,0,0,0,0,0,0,0 | cmp -s $touchscreendir/calibration_points # determine if calibration is still null -- means failed calibration
        if [ $? -eq 0 ] ; then
                echo "Touchscreen Calibration Failed"
                echo "Touchscreen Calibration Successful; Saving..."
                cat $touchscreendir/calibration_points > /sdcard/ts-calibration
FIXED in latest kernel version "htc-msm-linux-20100818_154417-package.tar" and newer ...

for calibration - you must delete the "ts_calibrate" file on your sdcard.

this problem is fixed in latest kernel.
if you use kernel "htc-msm-linux-20100818_154417-package.tar" or newer it is fixed.

the touchscreen problem (finger touch does recognize extra touch on left side ..) is not fixed now.

I am new, is it that we have to calibrate before we install?

On your first boot with the new zimage, it will ask you to calibrate the screen. If you made a mistake (or you did not calibrate at all), delete the ts-calibration file on your sd-card and start android again
