Есть монитор с резистивным тачскрином. Тач подключен через usb к расбери. Запускаю программу на qt5, программа работает но тач панель не реагирует на нажатие.

Что имеем более детально.

Изменил в фале sudo nano /usr/share/X11/xorg.conf.d/40-libinput.conf

libinput by evdev

получилось вот так:

  Section "InputClass"
      Identifier "evdev tablet catchall"
      MatchIsTablet "on"
      MatchDevicePath "/dev/input/event*"
      Driver "evdev"
  EndSection

Далее установил tslib и откалибровал:

Спойлер

apt-get install evtest libts-bin
apt-get install libts-dev
export TSLIB_TSDEVICE=/dev/input/event1  
export TSLIB_FBDEVICE=/dev/fb0:

калибровка и тест tslib работают.

Далее прописал окружения для qt5.15

export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/event1
export QT_QPA_EGLFS_NO_LIBINPUT=1
export QT_QPA_FB_TSLIB=1
export QT_QPA_GENERIC_PLUGINS=tslib:/dev/input/event1
