eGalax screen calibration (EeePC 900)

[Goudie]

Hi!

I installed eGalax resistive touch screen on my EeePC 900. It is well
recognized by Android but is not calibrated (horizontal inverted, off-
center ...).

It would be great if I could fix this little problem!

I tried the command "ts_calibration" as I have seen in other posts,
but it did not work (I can press targets, but does not change
anything). Even by disabling "zygote" before and restarting after.

is there a simple solution? I read that you could recompile the
installation ... I'm not good enough to do this kind of manipulation.

I should also say that I have not reinstalled my Android. I do not
know if this has an important (I'll try to do).

Thank you for your help!

I had the same issue with an eGalax resistive screen and an EEE PC 900.

You may try placing the attached pointercal file in system/etc

It may not be perfect, but should work fine provided that the panel
was installed with the ribbon on the lower right side of the screen. I
hope it helps.

Thank you very much !

I will try your pointercal file, and if it works, I am ready to reopen
my EeePC to replace the screen properly! :-D

I placed the file in /system/etc but nothing changed... :-( Always
inverted horizontally, always off center similarly.

It seems that the file is not being read there. Please try placing the
file or editing the existing files's values in

/data/system/tslib/pointercal

Thank you for your answer.

Root Explorer does not work on my Android (force close) but I put the
file in the folder you told me via Ubuntu.

After restart to Android, I can browse the system folders (no edit)
with OI File Manager : data folder appears, but empty ... The problem
is still there. :-(

It may be easier if you use ADB

turn on your device and let Android load, then check your andorid's
device IP addy and from ubuntu terminal do

adb connect IP addy

there you may go via shell command:

adb shell

or copy to Android:

adb push

or copy from Android:

abd pull

I used 2.2-r2 and to have the ts_calibrate to work you have to do
this :

create the folder /data/system/tslib/
run ts_calibrate and calibrate the touchscreen
this will create the pointercal file in /data/system/tslib/
reboot

Hi,

here is what worked for me using tslib and android x86 2.2r2:
install
create folder /data/system/tslib/
run ts_calibrate
check that /data/system/tslib/pointercal is created
reboot
bbye

Thanks Douglas and Alexandre.

I tried your various solutions, but that does not work. The pointercal
seems present in /data/system/tslib/ but the touch screen has not
changed. I will try with Android 2.2.

Whoohoo ! Thanks Alex ! I have reproduced point by point what you have
done in Android 2.2, and it works now! Great! Thank you!
