*warning: no input devices on entering weston. possible causes:- no
permissions to read /dev/input/event*- seats misconfigured (weston backend
option 'seat', udev device property ID_SEAT) *

My system is built on Linux Kernel and Busybox without using systemmd. Is
there any solution to support keyboard and mouse on txhis platform? backend
uses fbdev-backend.so
Many thanks

check that
- you have permissions to read /dev/input/event*
- ID_INPUT **and** ID_INPUT_MOUSE/ID_INPUT_KEYBOARD is set on the input
devices

if you're using libinput (judging by the error msg you do) it doesn't
actually care about ID_SEAT **unless* you want it to work on a specific seat
other than seat0.

Cheers,
Peter

Hello,
Thank you very much for your reply!
I login with root privilege, thus I have the permission to read
/dev/input/event*

Could you tell how to set ID_INPUT / ID_INPUT_MOUSE / ID_INPUT_KEYBOARD?

Is there any setting guide which is similar to Qt5'?
export QT_QPA_EVDEV_MOUSE_PARAMETERS=/dev/input/mouse0
export QT_QPA_EVDEV_KEYBOARD_PARAMETERS=/dev/input/event1

these are set by the udev builtin input_id. Check if udevadm info
/sys/class/input/eventX lists the properties, if not then you're missing
some steps in your udev setup.

Cheers,

I'm using Busybox root file system, and the default setting on Busybox is
mdev instead of udev. The device file of keyboard and mouse can be found in
/dev/input.
Qt4 works smoothly on this system and keyboard and mouse work well too.
