touchscreen intel x64 problem

met98 · May 2, 2019 at 10:55 PM

Hi everyone, I have a problem with my touch screen. I can't get it recognized properly. I installed libreelec on a x64 pc and I can't configure my egalax touch screen.

The touch works but has the axes reversed, I use the calibration tool but it gets stuck in the loading screen.

I've never had these problems with raspberry.

Read post #9

It's an older thread, so I don't know if it will apply to later versions of Libreelec

met98: if you use my touchscreen addon then you need to make some manual steps with configuration files. Not sure if this addons still works or not (don't have any hw to check).

Hi I have solved, for x64 there is a bug when crash ts_calibrate. I show you how I did it if it could be used by some other user (sorry for the english) for libreelec 9.0.1 x64 work fine

Code

install touchscreen addon (addon - service)

IN TO SSH
command ts_calibrate crash for x64, use ts_uinput_touch
to check what works
systemctl status service.touchscreen.service

Process: 641 ExecStart=/bin/sh -c exec /bin/sh /storage/.kodi/addons/service.touchscreen/bin/ts_uinput_touch.sh service (code=exited, status=1/FAILURE)
Process: 605 ExecStartPre=/bin/sh -c exec /bin/sh /storage/.kodi/addons/service.touchscreen/bin/ts_calibrate.sh service (code=exited, status=0/SUCCESS)

ts_uinput_touch it doesn't work for now

This is not a bug. As I wrote you need to configure thing manually.

It is good to know that this small piece of sw is still needed

in my case yes, if you tried to do ts_calibrate it gave:

Error in `ts_calibrate ': malloc (): memory corruption

Reading a bit I also found the solution for this

Thanks. I though malloc() error is because of misconfiguration. Will look what can be done.
