Introduction

Inputting Chinese on English Ubuntu system is not news. Ubuntu uses IBus keyboard input method system by default and there is Chinese input method ibus-pinyin which could be easily installed via sudo apt-get install ibus-pinyin. However, when it comes to gaming, especially in the full screen mode, ibus-pinyin will not show any word selection menu in the game, because it is in the IBus system and IBus system is not compatible with most of the gaming engines.


To support Chinese input in Ubuntu games, in this blog post, I will introduce how to install fcitx based input methods, which is compatible with games, on Ubuntu. It should also be noted that this method might also apply to the input methods from other languages.

Protocols

Installing Components

We would need to install fcitx and fcitx-googlepinyin first.

# Install fcitx input method system
$ sudo apt install fcitx-bin
# Install Google Pinyin Chinese input method
$ sudo apt install fcitx-googlepinyin

Ubuntu Setups

Change the input method system from IBus to fcitx in Region & Language.

Region & Language on Ubuntu 18.04

Click Manage Installed Languages.

IBus and fcitx

Click Install/Remove Languages to install Chinese Simplified and/or Chinese Traditional if necessary.


Remove all the input sources except English (US) under the Input Sources in Region & Language. Otherwise, there will be two input icons on your system.


Reboot the computer and we would see a new input icon at the top right corner of our desktop. We then add Google Pinyin to the fcitx method. We start the fcitx-configtool by running the following command in the terminal.

$ fcitx-configtool

Click + to add input methods.

fcitx Configuration

Uncheck Only Show Current Language, select Google Pinyin, and press OK.

Add Google Pinyin

Now you can start to use Google Pinyin by toggling using Ctrl + Space by default.

Ugly Default Idle Icon

The default fcitx icon at idle is ugly. We would like to make it look better. We run the following commands in the terminal.

# Remove classic UI
sudo apt remove fcitx-ui-classic
# Install new UI
sudo apt install fcitx-ui-qimpanel

Reboot the computer and we would see a new penguin input icon at the top right corner of our desktop. It will turn to a keyboard icon whenever the cursor is placed somewhere allows inputs.

Demo

Dota 2

In the game Dota 2, we press Ctrl + Space to switch to Google Pinyin and start to input Chinese.
