Hello,

Using tslib and evtest, able to detect the touch event, and its working fine on IMX8Mnano (Yocto project)

We would like to enable the touchscreen input support on the Weston GUI.

Can you please help me, what configuration is missing here? need to configure the ABS_MT_POSITION_X from kernel space?

Thanks,

I found the solution, I was missing display-coords in the dts configuration
