Hi,

Thank you for reporting the issue. I understand that you're unable to change the keyboard layout from us to jp in ~/.config/fcitx5/profile – the file keeps reverting or permissions/seem to enforce the default US layout.

Our engineer has provided the following solution. Please try it step by step:

1. Stop Fcitx5 first

Open a terminal and run:

killall fcitx5-help
killall fcitx5

2. Edit the profile file

Open the configuration file with a text editor (e.g., nano):

nano ~/.config/fcitx5/profile

Find the section [Groups/0] (or the group that contains Mozc). Change Layout=us to Layout=jp.

Example:

[Groups/0]
Name=Default
DefaultIM=mozc

[Groups/0/Items/0]
Name=keyboard-jp
Layout=jp   <-- change this to jp

Save the file and exit.

3. Restart Fcitx5

Start it again:

fcitx5 -d &

After this, the Japanese layout should be active for Mozc.

Alternative suggestion (GUI method):
You can also add the Japanese keyboard layout via the system settings:

Go to Control Center → Bluetooth & Devices → Keyboard → Input Method (or Keyboard Layout), then add Japanese (jp) layout. This might be easier and also avoids permission issues.

Thanks for your answers.
But , fcitx5 killall after login , fcitx5 restarted.

So , Power on and first login timing , typing ctrl+alt+f2 and CUI login , setting means deepin流云's ansered command (#sudo killall fcitx5 , edit of .config/fcitx5/profile and .config/fcitx5/config something...) and reboot.

*The means after install fcitx5-mozc and setting fcitx5-mozc on input method.
*Use Zenkaku_hankaku key at inputmode change , edit at .config/fcitx5/profile in [Hotkey/TriggerKeys] and Zenkaku_hankaku.(1=Zenkaku_hankaku etc...)
*This is a method that guarantees successful setup.

I'm reporting that issue has been resolved.
thx

This is a critical issue for Japanese users, so it needs to be fixed in a future release. Ideally, it would be great if Mozc were automatically configured during the initial setup of deepin in Japanese.

I've compiled some temporary solutions.
Please try configuring your settings using this information as a reference.

To developers: For Japanese language settings, it would be best if fcitx5-mozc were automatically installed when connected to the internet. The only necessary settings are to set .config/fcitx5/profile and .config/fcitx/config to Japanese and the Zenkaku_hankaku key.

I imagine development is quite challenging, but please keep up the good work.

thx
