(question)ibus-pinyin freezes in stumpwm

[wxie2017]

environment:

Debian GNU/Linux 12 - minimal installation without any desktop
apt install xorg, sbcl
apt install stumpwm
install ibus-pinyin

init files: .bash_profile ibus input

export GTK_IM_MODULE=ibus export XMODIFIERS=@im=ibus export QT_IM_MODULE=ibus ibus-daemon -drxR -v &

.xinitrc #!/usr/bin/env bash

eval gnome-keyring-daemon --start --components=gpg,pkcs11,secrets,ssh export GNOME_KEYRING_CONTROL export SSH_AUTH_SOCK export GPG_AGENT_INFO export GNOME_KEYRING_PID eval $(ssh-agent)

exec /usr/bin/stumpwm

setup: im-config -c use default

ibus-setup input method: I see English - English (US); I click ADD; then the setup window freezes, and I can C-c to kill it. The Chinese keyboard input method cannot be activated using s-SPC or any other methods.

What I miss in the process?
