[LINUX] I want to use Ubuntu's desktop environment on Android for the time being (Termux version-Japanese input in desktop environment)

Introduction

I want to use the Ubuntu desktop environment on Android for the time being (Termux version) It is a continuation of. Describes the settings for Japanese input in Ubuntu's LXDE and XFCE desktop environments. I'm using fcitx-anthy because fcitx-mozc just couldn't work (it should be on, but I can't type Japanese ...).

Installation

First, install Japanese fonts and Anthy (a tool for inputting Japanese from the keyboard). dbus-x11 makes up for the lack of input tools. After launching Ubuntu's LXDE or XFCE desktop environment, execute the following command in a shell such as LXTerminal.

apt install -y fonts-noto
apt install -y fcitx-anthy
apt install -y dbus-x11

Setting

Next, make the settings in the input tool settings dialog. Open the dialog with the following command.

fcitx-configtool

If the dialog does not open, execute the following command and then launch the dialog again.

fcitx-autostart

After displaying the input tool dialog, follow the steps below to set up Anthy.

1. Select the Input Method tab
2. Press the + button
3. Uncheck the Only Show Current Language checkbox
4. Enter Anthy in the input field below the checkbox
5. Anthy will appear in the box above, select it and press the OK button
6. Select Anthy so that Anthy is in the second position from the top, and then move it with the ↑ and ↓ buttons to the right of the + button.
7. Then select the Global Config tab
8. Set a button to switch between Japanese and English with the Trigger Input Method (*)
9. Press x at the top right of the dialog to close the dialog

• Optional. Looking on the net, it seems that the right ALT and Shift + SPACE are set as you like. If you're using Android Studio, change the default Ctrl + SPACE setting to something else. Ctrl + SPACE is a shortcut for Android Studio code completion.

Next, write the environment variables and the start command of fcitx in the configuration file. Execute the following command to edit the configuration file.

vim ~/.bashrc

Place the following in a suitable location in the .bashrc file. I listed at the bottom.

export GTK_IM_MODULE=fcitx
export QT_IM_MODULE=fcitx
export XMODIFIERS=@im=fcitx

fcitx > /dev/null 2>&1

Finally, quit Termux and XSDL and restart them. There are two lines of Termux in the notification area of Android, so tap the upper one. The word Exit will appear at the bottom left, so tap Exit to exit Termux. Follow the steps for each Android launcher to exit XSDL. If you start the desktop environment with Termux + XSDL again, you will be able to input Japanese with Anthy.

In my environment, I couldn't input Japanese with Anthy without restarting Termux. I couldn't load .bashrc with the souce command, so there may be something I have to do at startup.
