Many Ubuntu users, especially those who love customizing their keyboard layouts and behaviors, have faced this exact issue. The good news is, there are several ways to make your xkbset settings stick, and I'm here to walk you through them. Let's dive in and ensure your sticky keys, or any other xkbset magic, are there to greet you every time you log in. This comprehensive guide will explore various methods to achieve persistent xkbset configurations, ensuring your customized keyboard settings remain intact across sessions. We'll delve into the intricacies of startup scripts, desktop environment autostart mechanisms, and systemd services, providing you with the knowledge to choose the best approach for your specific needs. Whether you're a seasoned Linux user or just starting your Ubuntu journey, this guide will equip you with the tools to master xkbset persistence.

Understanding the Challenge

Before we jump into solutions, let's quickly understand why this happens. When you use xkbset commands directly in a terminal, the changes are applied to your current X session. However, these changes aren't automatically saved or applied when you start a new session. It's like setting a temporary wallpaper – looks great now, but gone after a restart. To make these changes permanent, we need to find a way to execute the xkbset commands automatically when your desktop environment starts. This involves understanding how Ubuntu manages startup applications and leveraging those mechanisms to our advantage. We need a persistent solution, something that tells the system, "Hey, remember these settings!" every time we log in. This persistent solution typically involves configuring a startup script or service that automatically executes the xkbset commands upon login. The key is to find the right place to put these commands so that they are executed at the appropriate time during the startup process. This might involve modifying configuration files within your user's home directory or creating a system-wide service that runs in the background.

Method 1: Using Startup Applications

One of the easiest ways to make xkbset settings permanent is by using the Startup Applications tool in Ubuntu. This tool allows you to specify applications or scripts that should run automatically when you log in. It's a user-friendly way to ensure your settings are applied at the beginning of each session. This method is particularly well-suited for users who prefer a graphical interface and want a straightforward approach to managing startup programs. The Startup Applications tool provides a simple interface for adding, editing, and removing applications that run at login, making it a convenient option for managing xkbset settings. By adding a custom command to execute your desired xkbset commands, you can ensure that your keyboard preferences are automatically applied each time you log in. This method avoids the need to manually edit configuration files or create complex scripts, making it accessible to users of all skill levels. The Startup Applications tool effectively bridges the gap between temporary command-line settings and persistent system-wide configurations, offering a user-friendly solution for managing your keyboard preferences.

Step-by-step Guide:

  1. Open Startup Applications: Search for "Startup Applications" in the Activities overview (the one you get when you press the Super key, also known as the Windows key). Fire up that Startup Applications app – it's your new best friend for making things run on login.
  2. Add a New Entry: Click the "Add" button. This will bring up a dialog where you can define a new startup application. Think of this as creating a little note for your system, reminding it to run your xkbset commands every time you log in.
  3. Name Your Application: Give your entry a descriptive name, like "Xkbset Sticky Keys" or something equally memorable. This helps you keep track of what each startup application does. A clear and concise name will make it easier to manage your startup applications in the future.
  4. Enter the Command: In the "Command" field, enter the xkbset commands you want to run. For example:
    xkbset sticky -twokey -latchlock && xkbset exp "=sticky"
    Make sure you include the full path to xkbset if it's not in your system's PATH. You can find the full path by running which xkbset in a terminal. This ensures that the system can locate and execute the xkbset command correctly. Double-check the syntax and options to avoid any errors during startup.
  5. Add a Comment (Optional): You can add a comment to further describe what this entry does. This is helpful if you have multiple startup applications and want to keep things organized. A brief comment can serve as a reminder of the purpose of the application, especially if you have several custom startup scripts.
  6. Save and Close: Click "Add" to save your new startup application. Close the Startup Applications window. Boom! You've just told your system to remember your xkbset settings.
  7. Test It Out: Log out and log back in to see if your settings are applied. If everything went according to plan, your sticky keys (or whatever you configured) should be active from the start. Give it a whirl and make sure your keyboard is behaving exactly as you expect.

Method 2: Using a .desktop File

Another method involves creating a .desktop file in the ~/.config/autostart directory. This is a more manual approach, but it offers greater control over how and when your commands are executed. Desktop files are the standard way to define applications and launchers in Linux desktop environments. By placing a .desktop file in the autostart directory, you instruct the system to launch the specified application or command automatically during startup. This method is particularly useful for users who want to fine-tune the execution order or add more complex startup logic. It allows for greater flexibility in customizing the startup process beyond the simple application launching provided by the Startup Applications tool. Understanding how .desktop files work is a valuable skill for any Linux user who wants to customize their desktop environment.

Step-by-step Guide:

  1. Create the Directory (If Needed): Open a terminal and run the following command to create the autostart directory if it doesn't already exist:
    mkdir -p ~/.config/autostart
    The mkdir -p command ensures that the directory is created even if its parent directories don't exist. This is a useful habit to adopt when working with the command line, as it avoids potential errors related to missing directories.
  2. Create the .desktop File: Use a text editor (like Nano, Vim, or Gedit) to create a new file named xkbset.desktop (or any name you prefer, as long as it ends with .desktop) in the ~/.config/autostart directory.
    nano ~/.config/autostart/xkbset.desktop
    Choosing a descriptive name for your .desktop file helps you identify its purpose at a glance. Using a text editor like Nano provides a simple and efficient way to create and edit the file directly in the terminal.
  3. Add the Configuration: Add the following content to the file:
    [Desktop Entry]
Name=Xkbset Sticky Keys
Comment=Enable sticky keys using xkbset
Exec=xkbset sticky -twokey -latchlock && xkbset exp "=sticky"
Terminal=false
Type=Application
StartupNotify=false
    Let's break down what each line means:
    • [Desktop Entry]: This section defines the entry as a desktop entry.
    • Name: The name of the application (displayed in the Startup Applications tool).
    • Comment: A brief description of the application.
    • Exec: The command to execute (your xkbset commands).
    • Terminal: Whether to run the command in a terminal (set to false for this case).
    • Type: The type of entry (set to Application).
    • StartupNotify: Whether to display a startup notification (set to false). The Exec line is where the magic happens – it tells the system exactly what commands to run when your session starts. The Terminal=false setting ensures that the commands are executed in the background without opening a terminal window.
  4. Save the File: Save the file and close the text editor. In Nano, you can do this by pressing Ctrl+O to save, then Ctrl+X to exit.
  5. Make it Executable (Optional): In most cases, the file will work without this step, but it's good practice to make the .desktop file executable:
    chmod +x ~/.config/autostart/xkbset.desktop
    The chmod +x command adds execute permissions to the file, ensuring that the system can run the commands specified in the Exec line.
  6. Test It Out: Log out and log back in to see if your settings are applied. Your sticky keys should now be enabled automatically.

Method 3: Using Systemd (Advanced)

For those who prefer a more system-level approach, or if the previous methods aren't working reliably, you can use Systemd to manage your xkbset settings. Systemd is a system and service manager for Linux operating systems, and it provides a powerful way to manage background processes and services. This method is particularly useful for users who want to ensure that their xkbset settings are applied early in the startup process, before the desktop environment is fully loaded. Systemd services offer a robust and reliable way to manage background tasks, providing features such as automatic restarting, dependency management, and logging. Creating a Systemd user unit allows you to run xkbset commands in the background as your user, ensuring that they are executed within your user session. This approach provides a more persistent and reliable solution compared to startup applications or .desktop files, as Systemd is designed to handle system-level tasks and services. However, it does require a bit more technical knowledge and familiarity with Systemd concepts.

Step-by-step Guide:

  1. Create the Systemd User Unit Directory (If Needed): Systemd user units are stored in ~/.config/systemd/user. Create this directory if it doesn't exist:
    mkdir -p ~/.config/systemd/user
    This command ensures that the necessary directory structure is in place before you create the Systemd unit file. Keeping your Systemd user units organized within this directory is a good practice for maintaining a clean and manageable system configuration.
  2. Create the Systemd Unit File: Use a text editor to create a new file named xkbset.service in the ~/.config/systemd/user directory:
    nano ~/.config/systemd/user/xkbset.service
    The .service extension is essential for Systemd to recognize the file as a service unit definition. Choosing a descriptive name like xkbset.service makes it easy to identify the purpose of the service.
  3. Add the Configuration: Add the following content to the file:
    [Unit]
Description=Xkbset Sticky Keys
After=graphical-session.target

[Service]
Type=forking
ExecStart=/usr/bin/xkbset sticky -twokey -latchlock && /usr/bin/xkbset exp "=sticky"
User=%i
Environment=DISPLAY=:0
Environment=XAUTHORITY=/home/%i/.Xauthority

[Install]
WantedBy=graphical-session.target
    Let's break down this configuration:
    • [Unit]: This section defines the unit's metadata, such as its description and dependencies.
      • Description: A human-readable description of the service.
      • After=graphical-session.target: This ensures that the service starts after the graphical session is initialized. This is crucial because xkbset needs the X server to be running.
    • [Service]: This section defines how the service should be executed.
      • Type=forking: This tells Systemd that the service will fork a background process.
      • ExecStart: The command to execute (your xkbset commands). Make sure to use the full path to xkbset.
      • User=%i: This tells Systemd to run the service as the user who started the graphical session.
      • Environment=DISPLAY=:0: This sets the DISPLAY environment variable, which is necessary for X applications to run.
      • Environment=XAUTHORITY=/home/%i/.Xauthority: This sets the XAUTHORITY environment variable, which is used for X authentication.
    • [Install]: This section defines how the service should be installed.
      • WantedBy=graphical-session.target: This tells Systemd to start the service when the graphical session target is reached. The After=graphical-session.target directive is essential for ensuring that the service starts after the graphical environment is ready, preventing potential errors related to the X server not being available.
  4. Save the File: Save the file and close the text editor.
  5. Enable the Service: Run the following commands to enable and start the service:
    systemctl --user enable xkbset.service
systemctl --user start xkbset.service
    The systemctl --user enable command creates a symbolic link in the user's Systemd configuration directory, ensuring that the service starts automatically on login. The systemctl --user start command starts the service immediately, allowing you to test it without logging out and back in.
  6. Test It Out: Log out and log back in to see if your settings are applied. Alternatively, you can check the service status using systemctl --user status xkbset.service to see if it's running correctly. If the service is running as expected, your xkbset settings should be applied automatically.

Troubleshooting Tips

Sometimes, things don't go exactly as planned. If your xkbset settings aren't being applied, here are a few things to check:

  • Check the Path: Make sure you're using the full path to xkbset in your commands or scripts. You can find the full path by running which xkbset in a terminal.
  • Check for Errors: If you're using a .desktop file or Systemd service, check the logs for any errors. For Systemd, you can use the journalctl --user -u xkbset.service command.
  • Permissions: Ensure that your .desktop file is executable (chmod +x ~/.config/autostart/xkbset.desktop).
  • Dependencies: If you're using Systemd, make sure the service is starting after the graphical session is initialized (After=graphical-session.target).
  • Syntax: Double-check the syntax of your xkbset commands. A small typo can prevent them from working.
  • Multiple Instances: Avoid running multiple instances of xkbset commands simultaneously, as this can lead to conflicts. Ensure that only one instance of your startup script or service is running at any given time.
