Hi, whatever you have or do, you need to set up the device attributes the way libinput expects them to be to recognize an input device as a keyboard or a mouse or other. You can look into libinput source code to see how it queries the devices through the libudev API, and then figure out how to make mdev return the data libinput expects. Hopefully you find a way to at least hardcode your input device types with mdev - a proper system with udev uses some tools that try to infer the device type from the kernel evdev features it supports automatically, AFAIU. For more information, see: https://wayland.freedesktop.org/libinput/doc/latest/device-configuration-via-udev.html I have no idea what mdev is or how it works, so I cannot say if that is possible. Please, let us know how it goes, so that we have something to say to the next person asking similar questions.

Re: I've got a question to ask you
I'm using Busybox root file system, and the default setting on Busybox is mdev instead of udev. 박성진 于2018年8月28日周二 上午11:58写道： > Hi, > > as weston creates libinput udev context by default, you'd better to > prepare udev daemon for it. > > Otherwise, you can create your own fbdev backend using > libinput_path_create_context() / libinput_path_add_device(). > > > > Best regards, > > Sung-Jin Park > > > > - *Original Message* - > > *Sender* : binnan hao > > *Date* : 2018-08-28 12:35 (GMT+9) > > *Title* : I've got a question to ask you > > > I've got a question to ask you.

RE: I've got a question to ask you
Hi, as weston creates libinput udev context by default, you'd better to prepare udev daemon for it. Otherwise, you can create your own fbdev backend using libinput_path_create_context() / libinput_path_add_device(). Best regards, Sung-Jin Park - Original Message - Sender : binnan hao Date : 2018-08-28 12:35 (GMT+9) Title : I've got a question to ask you I've got a question to ask you. The Linux system I'm using is built on my own (Kernel+Busybox), and it does not contain other extra things. Now I want to use weston(fbdev-backend.so), but the keyboard and mouse do not work and log gives following message: 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) I have root permission and device files can be found in path /dev/input/. I do not want to add anything else, as that may lead to a very large size system.
