Hi,
I’m trying out LVGL and I’m having some trouble getting the keyboard integration to work. When I build the demo application using the SDL driver, everything is working fine. But when I switch to the wayland or fbdev+evdev/libinput driver, the keyboard input does not seem to work. When I move to one of the input fields in the application, the on-screen keyboard appears, and I can input text using the on-board keyboard. But when pressing a key on the keyboard, nothing seems to happen.
I have enabled the necessary driver options (USE_WAYLAND, USE_EVDEV, USE_LIBINPUT, USE_XKB) and use the correct /dev/input/eventX devices for the mouse and keyboard.
When adding some extra logging to the keyboard read function, I can see it’s being called and the pressed keys are also being read correctly:
[Error] (4.338, +35) _lv_wayland_keyboard_read: _lv_wayland_keyboard_read: key=111 state=0 (in wayland.c line #2172)
[Error] (4.372, +34) _lv_wayland_keyboard_read: _lv_wayland_keyboard_read: key=111 state=0 (in wayland.c line #2172)
[Error] (4.406, +34) _lv_wayland_keyboard_read: _lv_wayland_keyboard_read: key=111 state=0 (in wayland.c line #2172)

[Error] (4.467, +30) _lv_wayland_keyboard_read: _lv_wayland_keyboard_read: key=111 state=0 (in wayland.c line #2172)
[Error] (4.503, +36) _lv_wayland_keyboard_read: _lv_wayland_keyboard_read: key=111 state=0 (in wayland.c line #2172)
But I don’t see any effect in the application. What am I doing wrong?
