Checking Default Ubuntu Settings

Before we get into the nitty-gritty, let’s check the obvious. Ubuntu has built-in settings for keyboard shortcuts, and the Print Screen key might be disabled or assigned to something else. We'll walk through how to access these settings and see if anything's amiss. Navigating through the Ubuntu settings can sometimes feel like a maze, so we'll provide clear, step-by-step instructions to ensure you can easily find the relevant configurations. We'll specifically focus on the "Keyboard Shortcuts" section, where you can view and modify the actions assigned to various key combinations. We'll guide you on how to locate the Print Screen shortcut and verify its current setting. Is it disabled? Is it assigned to a different screenshot utility? Is it conflicting with another shortcut? These are the questions we'll answer as we explore the default Ubuntu settings. We'll also discuss the different screenshot tools that come pre-installed with Ubuntu, such as GNOME Screenshot, and how they might interact with the Print Screen key. Understanding these interactions is key to avoiding conflicts and ensuring that your desired screenshot behavior is achieved. By the end of this section, you'll have a clear picture of how Ubuntu is currently handling the Print Screen key, and you'll be well-equipped to make any necessary adjustments.

Step-by-step guide to checking keyboard settings:

  1. Open Settings. You can usually find this by searching in the Activities overview (the one you get when you press the Windows key or click Activities in the top-left corner).
  2. Go to Keyboard settings.
  3. Scroll down to Screenshots section.
  4. See what action is assigned to the Print Screen key.

Using xmodmap to Remap the Key

If the settings look fine, or you want more control, we can use xmodmap. This is a powerful command-line tool that lets you modify keyboard keymaps in X Window System (which Ubuntu uses). This section will delve into the powerful world of xmodmap, a command-line tool that provides granular control over keyboard keymaps in the X Window System. We'll start by explaining what xmodmap is and how it interacts with the underlying keyboard mapping mechanisms in Ubuntu. We'll then walk you through the process of using xmodmap to identify the keycode associated with your Print Screen key on the Logitech MX Mechanical. This is a crucial step, as keycodes are the unique identifiers that xmodmap uses to remap keys. Once we've identified the keycode, we'll show you how to use xmodmap commands to assign the desired Print Screen functionality to that keycode. This might involve remapping the key to the standard Print Screen function or assigning it to a specific screenshot utility. We'll also cover how to test your changes and ensure that the remapping is working correctly. But the magic of xmodmap doesn't stop there. We'll also explore how to make your xmodmap changes permanent, so they persist across reboots and login sessions. This involves creating a configuration file and ensuring that it's loaded automatically when your system starts. By the end of this section, you'll have a comprehensive understanding of how to use xmodmap to customize your keyboard layout, specifically focusing on enabling the Print Screen key on your Logitech MX Mechanical keyboard. You'll be empowered to tweak your keyboard to your exact preferences, unlocking a new level of customization and efficiency.

Finding the Keycode

Open a terminal (Ctrl+Alt+T) and run xev. This tool shows you events generated by X Window. Press your Print Screen key. You'll see a bunch of output, but look for the line that starts with KeyPress and note the keycode. It will be a number. The keycode is your key's identifier.

Remapping the Key

Now that you have the keycode (let's say it's 107 for this example, but yours might be different), you can remap it. Run this command in the terminal:

xmodmap -e "keycode 107 = Print"

Replace 107 with your keycode. This command tells xmodmap to assign the Print keysym (symbol) to your key. You might need to use Print or Sys_Req depending on your system's configuration.

Making it Permanent

This change is temporary and will be lost when you restart. To make it permanent:

  1. Create a file named .xmodmaprc in your home directory if it doesn't exist:

    nano ~/.xmodmaprc

  2. Add the xmodmap command to this file:

    keycode 107 = Print

    Again, replace 107 with your keycode.

  3. Save the file (Ctrl+O in Nano) and exit (Ctrl+X).

  4. Make the system load this file on login. Open your startup applications (search for "Startup Applications" in the Activities overview) and add a new entry. Name it something like "xmodmap" and use this command:

    xmodmap ~/.xmodmaprc

Using sxhkd for Advanced Configuration

For those who want even more control, sxhkd is a powerful keyboard daemon for X. It allows you to bind keys to commands. This section explores the advanced capabilities of sxhkd, a powerful keyboard daemon for the X Window System that unlocks a new level of customization for your keyboard. We'll start by explaining what sxhkd is and how it differs from xmodmap. While xmodmap remaps keys at a lower level, sxhkd allows you to bind specific key combinations to commands, providing much greater flexibility. We'll guide you through the installation process of sxhkd on Ubuntu, ensuring you have the necessary dependencies and configurations in place. Once sxhkd is installed, we'll delve into the configuration file, where you define your keybindings. We'll show you how to create simple keybindings, such as assigning the Print Screen key to a specific screenshot utility, and then progress to more complex scenarios, such as binding multiple keys to different actions based on the context. We'll also explore the powerful concept of chaining commands in sxhkd, allowing you to create sophisticated workflows with a single keypress. This is where sxhkd truly shines, enabling you to automate tasks and boost your productivity. But sxhkd isn't just about functionality; it's also about customization. We'll show you how to customize the appearance and behavior of sxhkd, ensuring it integrates seamlessly with your desktop environment. By the end of this section, you'll be a sxhkd master, capable of crafting intricate keybindings that perfectly match your needs and preferences. You'll be able to transform your keyboard into a personalized command center, streamlining your workflow and maximizing your efficiency.

Installing sxhkd

First, you need to install it. Open a terminal and run:

sudo apt install sxhkd

Configuring sxhkd

sxhkd reads its configuration from ~/.config/sxhkd/sxhkdrc. If the directory or file doesn't exist, create them:

mkdir -p ~/.config/sxhkd
nano ~/.config/sxhkd/sxhkdrc

Add a line to bind the Print Screen key to a screenshot command. For example, to use the gnome-screenshot tool:

Print
    gnome-screenshot

You can use other tools like scrot or Flameshot here too.

Running sxhkd

You need to start sxhkd and make it start on login. Add it to your startup applications, just like we did with xmodmap. The command to run is simply sxhkd.
