Unable to find Device

[Koravya]

xlibinput_calibrator is unable to identify my touchscreen. I have attempted to force it by specifying the --device-name and/or the --device-id properties. My system is a Dell XPS 9575 2-IN-1. Here is /proc/bus/input/devices entry fro the devices.

Hi,

first, you can pass the device id, where the id is the one returned by "xinput --list" and NOT by "libinput list-devices".

If this doesn't solve your problem, please could you show the output of

$ xinput --list

and the output of

$ xinput list-props

where are/is the id associated to the wacom device(s) ? May be that the wacom is not classified as touchscreen, but as another type (like touchpad).

I am not familiar with this type of device. So I am assuming that it is like an absolute "mouse", where when you press the pen is like when you press a mouse button ? And, why you need xlibinput_calibrator ? I guessing that the corner of the tablet is not coincident with the corner of of the monitor ? If so, how big is the differences ? 10%.. 100% ... 1000% ?

Sorry for the questions, but I need to know these information to better understand

Under normal operation (Only using the onboard display) the devices work perfectly. I recently bought a portable external monitor, when I connect it to the system both it's touch, and the wacom touch get scale to the entire window. xlibinput_calibrator works perfectly for the external device, fixing the calibration so that it applies to the correct display. However it is unable to identify the onboard screen, and thus the calibration stays wrong. When i disconnect the external display the onboard touch returns to normal.

Ok, from the output I see the problem: xlibinput_calibrator try to change the "libinput Calibration Matrix"; however your device doesn't expose this matrix, but it has only 'Coordinate Transformation Matrix (147)'. I have to try to change this matrix instead of "libinput Calibration Matrix". Let me few days and I will create a patch to let the user to specify which 'matrix' has to be manipulated.

[kreijack]

Ok, I updated the 'devel' branch, adding the --matrix-name option.

So you should be able to calibrate

$ ./xlibinput_calibrator --device-id=13 "--matrix-name=Coordinate Transformation Matrix" --verbose

Looking forward for a feedback.

So far this appears to fix it. I will continue to test over the next few days to be sure.

[kreijack]

Ok. Please give me in any case a feedback. If something goes wrong, I am open to analyze your bug report.

I apologize for such a late response. Below is the printout from the last usage. It worked as intended.
