PyQT Touch Events (Raspberry Pi 5 and Ubuntu 24.04)

[OOOllieMCL]

Hi all,

I am having an issue that QT is only ever receiving touch events when I press the screen with 3 fingers, I have an application running on my desktop in Ubuntu 24.04. I can press on the desktop and all events are recorded fine for other applications. I've used xinput to calibrate the screen as well and other applications such as Firefox accurately touch clicks.

Ive set the attributes on the widgets and I can add that it works fine on Windows with the touch screen as well. Is there anything I need to do to enable the support for this on a Linux environment? I use X11 instead of Wayland and installed PyQt with pip.

I get no information from the event filter that any event is happening when I press with a single finger.

Hi @OOOllieMCL ,

I write the same message as i've some minutes ago. You can try to enable logs:

Can you try using Wayland -> Wayfire in sudo raspi-config?
