Debian Mouse Configuration
Introduction
Mouse configuration in Debian is an essential aspect of customizing your Linux experience. Whether you're a programmer who needs precise cursor control or a regular user who wants to optimize your workflow, understanding how to configure your mouse in Debian can significantly enhance your productivity and comfort.
In this guide, we'll explore various methods to customize mouse settings in Debian, from graphical user interfaces to command-line tools. We'll cover adjusting sensitivity, changing scroll behavior, configuring button mappings, and setting up more advanced options.
Basic Mouse Configuration via GUI
For beginners, the easiest way to configure your mouse is through Debian's graphical interface. The exact appearance might vary depending on your desktop environment (GNOME, KDE, XFCE, etc.), but the general process is similar.
GNOME Desktop Environment
If you're using GNOME (Debian's default desktop environment):
- Open the Settings application
- Navigate to Mouse & Touchpad section
- Adjust the following common settings:
- Primary button (left or right-handed use)
- Pointer speed
- Natural scrolling
- Acceleration profile
Here's how these settings affect your mouse behavior:
Setting | Effect |
---|---|
Primary button | Swaps left and right mouse buttons |
Pointer speed | Controls how far the cursor moves in response to physical mouse movement |
Natural scrolling | Reverses scroll direction (like on touchscreens) |
Acceleration profile | Determines how pointer speed increases with faster movements |
KDE Plasma Environment
In KDE Plasma:
- Open System Settings
- Go to Input Devices → Mouse
- Configure similar options to those in GNOME
Command-Line Mouse Configuration
Many Debian users prefer command-line tools for greater control and automation possibilities. Let's look at some powerful CLI tools for mouse configuration.
Using xinput
The xinput
tool allows you to list and modify input device properties. It's particularly useful for configuring specific device features.
First, install xinput if you don't have it already:
sudo apt update
sudo apt install xinput
Listing Mouse Devices
To see all input devices:
xinput list
Output might look like:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech M510 id=10 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Generic Keyboard id=9 [slave keyboard (3)]
In this example, our mouse is "Logitech M510" with id=10.
Viewing Properties
To see all properties of your mouse:
xinput list-props 10 # Replace 10 with your device ID
Changing Settings
To modify a property, use set-prop
:
# Set pointer acceleration (sensitivity)
xinput set-prop 10 "libinput Accel Speed" 0.5
# Disable acceleration for more predictable movements (good for gaming)
xinput set-prop 10 "libinput Accel Profile Enabled" 0, 1
Using xset
The xset
utility provides another way to configure mouse behavior:
# Set mouse acceleration and threshold
xset m 2 4
# Disable mouse acceleration
xset m 0 0
In the first example, 2
is the acceleration multiplier and 4
is the threshold (speed at which acceleration kicks in).
Configuring Mouse in X11 Configuration Files
For permanent changes that apply at system startup, you can create X11 configuration files.
Create a file in /etc/X11/xorg.conf.d/
directory (create this directory if it doesn't exist):
sudo mkdir -p /etc/X11/xorg.conf.d/
sudo nano /etc/X11/xorg.conf.d/90-mouse.conf
Add configuration like this:
Section "InputClass"
Identifier "My Mouse"
MatchIsPointer "yes"
Option "AccelerationProfile" "0"
Option "AccelerationScheme" "none"
Option "AccelSpeed" "-0.5"
EndSection
Save and exit. These changes will apply after you restart your X server (or reboot).
Advanced Mouse Configurations
Button Mapping
You can reassign the functions of mouse buttons with xinput:
# First, check current button mapping
xinput get-button-map 10
# Change button mapping (swap left and right buttons)
xinput set-button-map 10 3 2 1
The numbers represent button functions in order. The default is typically 1 2 3 4 5 6 7
, where:
- 1 = left click
- 2 = middle click
- 3 = right click
- 4 = scroll up
- 5 = scroll down
- 6, 7 = side buttons
Using imwheel for Custom Scroll Behavior
The imwheel
utility allows for more customizable scroll behavior:
sudo apt install imwheel
Create a configuration file:
nano ~/.imwheelrc
Add customizations like:
".*"
None, Up, Button4, 3
None, Down, Button5, 3
Control_L, Up, Control_L|Button4
Control_L, Down, Control_L|Button5
Shift_L, Up, Shift_L|Button4
Shift_L, Down, Shift_L|Button5
This configuration:
- Makes the scroll wheel move 3 lines at a time
- Maintains Ctrl+scroll and Shift+scroll behaviors
Start imwheel:
imwheel -b "4 5"
To have imwheel start automatically, add it to your startup applications.
Configuring Gaming Mice
Gaming mice often have additional buttons and DPI settings. While some might need proprietary software, many can be configured in Debian:
Using Piper for Gaming Mice
Piper is a GTK application to configure gaming mice supported by libratbag:
sudo apt install piper
Launch Piper and you can configure:
- Button mappings
- LED colors (for RGB mice)
- DPI settings
- Polling rate
Using the HID Driver Directly
For advanced users, you can configure certain aspects by writing to sysfs:
# Example: Changing polling rate to 1000Hz for a device
echo 1 > /sys/bus/usb/devices/YOUR_DEVICE_ID/polling_rate
Troubleshooting Common Issues
Mouse Too Fast/Slow
If your mouse is too sensitive or not sensitive enough:
# Using xinput (adjust value between -1 and 1)
xinput set-prop "Your Mouse Name" "libinput Accel Speed" -0.5
# Using xset (first number is acceleration, second is threshold)
xset m 1 1
Erratic Movement
If your mouse movement is erratic, try disabling acceleration:
xinput set-prop "Your Mouse Name" "libinput Accel Profile Enabled" 0, 1
Middle-Click Paste Not Working
If middle-click paste isn't working:
# Check button mapping
xinput get-button-map "Your Mouse Name"
# Ensure middle button (usually 2) is correctly mapped
xinput set-button-map "Your Mouse Name" 1 2 3 4 5 6 7
Making Configurations Persistent
To make mouse configurations apply at every boot:
- Create a startup script:
nano ~/.config/autostart/mouse-config.sh
- Add your configuration commands:
#!/bin/bash
xinput set-prop "Your Mouse Name" "libinput Accel Speed" -0.5
xinput set-prop "Your Mouse Name" "libinput Accel Profile Enabled" 0, 1
- Make the script executable:
chmod +x ~/.config/autostart/mouse-config.sh
- Create a desktop entry:
nano ~/.config/autostart/mouse-config.desktop
- Add:
[Desktop Entry]
Type=Application
Name=Mouse Configuration
Exec=/home/YOUR_USERNAME/.config/autostart/mouse-config.sh
Hidden=false
X-GNOME-Autostart-enabled=true

to identify your mouse, then usexinput list-props
to examine all available properties. - Create a script that configures your mouse to your liking and add it to your startup applications.
- Experiment with different acceleration profiles to find which works best for you.
- If you have a multi-button mouse, try remapping some of the extra buttons to useful functions.
- Configure natural scrolling and test whether you prefer it over traditional scrolling.
