Hi Petr, If you think it is related to calibration, you can try xinput_calibrator. Its a generic touchscreen calibration utility (still depends on GTK-mm for now, will be fixed in the next version): http://www.freedesktop.org/wiki/Software/xinput_calibrator
If you have a recent version of the X server and evdev, it can dynamically recalibrate the evdev driver. If not, it will print the min/max X and Y values on stdout. It calibrates the Xorg driver (and the values that the X server receives). You report calibrating from the values of the kernel, maybe using a user-space tool will solve your problem ? If you want to find out what the X server thinks of your touchscreen actions, install xinput and run: > xinput test "TS name" you can also check the output of > xinput query-state "TS name" to find out the exact coordinates of your touches. (this will probably be similar to the 'xidump' you mentioned though) Kind regards, Tias Petr Štetiar wrote: > Hi, > > I'm trying to get working 22" resistive 5-wire touchscreen with USB > controller, it's ET&T TC5UH[1].
