Using wayland in i.mx6 Quad

Hi,

I'm using wayland in i.mx6 Quad.

Kernel version is 4.1.15 and Qt version is 5.8, wayland and weston version is 1.9.0.

I have some problem. That is combobox that makes Qt.

If you use the mouse, it will work normally, but if you use touch screen, Qt program will stop.

Please let me know if you know of a solution.. I have been having this problem for two months ... :smileysad:

Hello Huh,

Please check the QT page:

Qt for Embedded Linux | Qt 5.11

Also in

Device Drivers -> HID Devices -> Special HID drivers -> HID Multitouch panels as an embedded driver (*) in my Kernel configuration, and then added touchscreen's Vendor ID and Device/Product ID to the kernel drivers table and rebuilt the Kernel.

this is the config file:

#
# Input device support
#
CONFIG_INPUT=y
# CONFIG_INPUT_FF_MEMLESS is not set
CONFIG_INPUT_POLLDEV=y
# CONFIG_INPUT_SPARSEKMAP is not set
# CONFIG_INPUT_MATRIXKMAP is not set

#
# HID support
#
CONFIG_HID=y
# CONFIG_HID_BATTERY_STRENGTH is not set
# CONFIG_HIDRAW is not set
# CONFIG_UHID is not set
CONFIG_HID_GENERIC=y

#
# USB HID support
#
CONFIG_USB_HID=y
# CONFIG_HID_PID is not set
# CONFIG_USB_HIDDEV is not set

And when you do lsmod output does not show hid_multitouch module - because you built as an embedded driver (not as a module).

Regards
