Попал в засаду с линуксом. Точнее с дисплеем адвантек, а именно с тач. Не хочет работать тач в qt5.
Что делал.
Сначала подключил дисплей к малине. После выполнил команду lsusb

Выше показал реакции а нажатия тач. Далее пытался настроить калибровку тачскрин. Делал:
apt-get install evtest libts-bin
apt-get install libts-dev
export TSLIB_TSDEVICE=/dev/input/event1
export TSLIB_FBDEVICE=/dev/fb0:
Калибровка запустилась и тач заработал. Далее заменил
libinput на evdev в файле nano /usr/share/X11/xorg.conf.d/40-libinput.conf
Section "InputClass"
Identifier "evdev tablet catchall"
MatchIsTablet "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
EndSection
Добавил
export TSLIB_TSDEVICE=/dev/input/event1
ts_calibrate
export QWS_MOUSE_PROTO=tslib:/dev/inut/event1
Но qt не работает тач. Кнопки не нажимаются
