QT touch issue

[ROSHAN RAJAGOPAL]

Hello,

I am encountering a unique issue with the touchscreen on our custom 5728 board. We have a custom board that runs the Weston display manager, and we've configured a Qt application to start automatically after every boot.

The problem we're facing is that, in about 2 out of 10 boot cycles, the touchscreen does not respond to our Qt application or when the Qt application is left ideal for a long time like 2 days , although it does respond to Weston's default applications like the Weston editor and terminal. We have used the "evtest" tool to verify the touch inputs, and it seems that the touch events are being detected properly with no apparent issues.

We are using:

Weston version: 2.0.0
Qt version: 5.9.7
Touchscreen driver: ar1021

.

Regards,
Roshan Rajagopal

Hi Roshan,
have you tried with a more recent Qt Version? Qt 5.9 is no longer supported. Which OS are you using?
Cheers

@Axel-Spoerl we have build a custom OS which uses weston , this was done using ti-sdk 5.03 which has qt5.97 inbuilt and now we are facing this issue of only QT apps touch not working whereas weston works perfectly , ours is a embedded linux platform

Then I would strongly recommend to upgrade to Qt 6.5.
It's impossible to troubleshoot on 5.9.
