something is wrong with the program ev_calibrate

Asked by Антон Бородин on 2009-04-08

On my laptop (Asus Eee PC 701 4G) installed touchscreen eGalax. It runs Jaunty NBR ant worked nice before last (yesterday) update. Now has the problem:
When starts ev_calibrate it shows:
in upper-left corner min_max.cur_y ~1150
in upper-right corner min_max.cur_y ~1200
in down-right corner min_max.cur_y ~1990
in down-left corner min_max.cur_y ~1990
in upper-center crosshair y ~1700 right like in left- and right-center crosshair ant therefore /etc/evtouch/config, generated after calibrate does not allow navigate accurately.
I don't know, is this a hardware, or software bug, but I think it possible to calculate X,Y(0-8) factors "by hand".
Where can I find explanatory information concerning the appointment of these factors? Unfortunately, the source driver, I get this information will not be able to - programming is not my strong side.

Ok, I was wrong. Problem is in damaged or defective touch panel.
