[Bug]: Can't switch USB keyboard language in fcitx5

[hansm629]

Problem description

pkg install fcitx5*

In the Termux native XFCE desktop environment (Samsung DeX Mode) After installing fcitx5 using the above command,

From USB keyboard Via Shift + Space or Ctrl + Spece or right Alt key I tried switching between Korean and English, but it doesn't work.

Even though “Prefer scancodes” is set in Termux-X11 It doesn't work.

in 'PRoot-Distro Debian environment` If you test it after installing ibus or fcitx5,

Shift + Space or Ctrl + Spece or right Alt key Switching between Korean and English works very well.

If this symptom is not a bug Are there any settings I missed?

Come to think of it Generally, in Linux, there is a separate fcitx5-hangul package for Korean language support. It appears that this package does not exist in fcitx5 ported to Termux.

Could this have anything to do with it?

What steps will reproduce the bug?

• Install all fcitx5 packages in Termux
• Added Korean keyboard in fcitx5 settings
• Language switching key setting (Shift+Space or Ctrl+Spece or Right Alt)
• Added automatic execution of fcitx5 upon login in XFCE session.
• Even if you press the language switch key set in fcitx5 on the USB keyboard, it does not switch to Korean.
• Korean switching on USB keyboard works well with fcitx5 and ibus in PRoot Linux environment.

What is the expected behavior?

There is nothing left to guess.
