How To Restart iBus in Ubuntu

Ubuntu 6

In this article, we will delve into the process of restarting iBus in Ubuntu. iBus is an Intelligent Input Bus, a critical component in Linux distributions that facilitates input methods for different languages. However, there may be times when you need to restart iBus, especially if you’re experiencing issues with it.

Quick Answer

To restart iBus in Ubuntu, you can either restart the iBus daemon using the command ibus-daemon & in the terminal or modify the .bashrc file by adding the lines export GTK_IM_MODULE=ibus, export XMODIFIERS=@im=ibus, and export QT_IM_MODULE=ibus. Another option is to install a different iBus engine if you’re experiencing issues with a specific one.

Understanding iBus

iBus is an open-source framework designed to provide a unified interface for input methods. It’s widely used in Linux distributions to support typing in languages that require complex input methods, such as Chinese, Japanese, and Korean.

Why Restart iBus?

Sometimes, iBus may encounter problems, such as not recognizing specific input methods or failing to switch between different input methods. In such cases, restarting iBus can help resolve the issue.

Method 1: Restarting iBus Daemon

The first method involves restarting the iBus daemon. Here’s how you can do it:

  1. Open a terminal. You can do this by pressing Ctrl + Alt + T or by searching for ‘Terminal’ in your applications menu.
  2. Enter the following command to ensure that iBus is properly exited:
ibus exit
  1. Restart iBus by entering the following command:
ibus-daemon &

In this command, ibus-daemon is the process that runs iBus, and the & symbol ensures that this process runs in the background.

If you want to keep the iBus daemon running even after closing the terminal, use the following command instead:

nohup ibus-daemon &

Here, nohup stands for ‘no hangup’, which allows the process to continue running even after the terminal is closed.

Method 2: Modifying the .bashrc File

Another method to restart iBus involves modifying the .bashrc file. Follow these steps:

  1. Open the .bashrc file located in your home directory using a text editor. You can do this by entering the following command in the terminal:
sudo gedit ~/.bashrc
  1. Add the following lines to the file:
export GTK_IM_MODULE=ibus
export XMODIFIERS=@im=ibus
export QT_IM_MODULE=ibus

These lines set the input method for GTK, X, and Qt applications to iBus.

  1. Save the file and log out and back in for the changes to take effect.

Method 3: Installing a Specific iBus Engine

If you’re experiencing issues with a particular iBus engine, you can try installing a different one. Here’s how:

  1. Download the source code of the desired iBus engine from a reliable source, such as GitHub.
  2. Build and install the engine following the provided instructions. This usually involves entering a command like make install in the terminal.
  3. Install the necessary dependencies. For example, you may need to enter the following commands:
sudo apt install ibus
sudo apt-get install ibus-gtk3
  1. After logging out, restart iBus using the command ibus restart and configure it using ibus-setup.


Restarting iBus in Ubuntu is a straightforward process that can be accomplished in a few different ways. Whether you’re troubleshooting an issue or simply switching to a different input method, these methods should help you restart iBus effectively. As always, remember to consult the iBus documentation or seek further assistance if you encounter any difficulties.

Can I restart iBus without using the terminal?

Yes, you can restart iBus without using the terminal. You can restart iBus by logging out and logging back in, as this will restart the iBus process.

Will restarting iBus affect my current input method settings?

No, restarting iBus will not affect your current input method settings. It will only restart the iBus process, ensuring that it functions properly.

How do I check if iBus is running?

You can check if iBus is running by opening a terminal and entering the command ibus status. This command will display the current status of iBus and indicate whether it is running or not.

Can I restart iBus in other Linux distributions?

Yes, you can restart iBus in other Linux distributions using similar methods. However, the specific commands or file locations may vary depending on the distribution. It’s always recommended to consult the documentation or community support for your specific distribution.

What should I do if restarting iBus doesn’t resolve my issue?

If restarting iBus doesn’t resolve your issue, you can try reinstalling iBus or the specific iBus engine you are having trouble with. You can also seek further assistance from the iBus community or forums to troubleshoot your specific problem.
