Slowed/smoothed touch pad movement; 2022 dell xps 15; Arch linux

Introduction

If you've been experiencing sluggish or overly smooth touchpad movements on your 2022 Dell XPS 15 while running Arch Linux, you're not alone. This issue can often hinder productivity and create frustration when navigating your system. In this article, we will address the problem of slowed or smoothed touchpad movement, provide potential solutions, and optimize your touchpad settings for an improved experience.

Understanding the Problem

The problem at hand is the sluggishness of the touchpad movement on the Dell XPS 15 running Arch Linux, which can result in a less responsive user experience. Often, this is due to configuration settings or driver compatibility issues that need adjustment. Here's the original issue summarized succinctly:

"Slowed/smoothed touchpad movement on 2022 Dell XPS 15 running Arch Linux."

Original Code and Configuration

Here’s a common example of how touchpad settings might look in the xorg.conf.d file, which could be the source of the issue:

Section "InputClass"
    Identifier "touchpad"
    MatchIsTouchpad "on"
    Driver "libinput"
    Option "Tapping" "on"
    Option "NaturalScrolling" "true"
    Option "DisableWhileTyping" "true"
EndSection

Analysis and Solutions

1. Check Touchpad Driver

Arch Linux typically uses libinput or synaptics as drivers for touchpads. Ensure you're using the appropriate driver for your touchpad.

  • libinput is recommended for its modern features and support. If you're experiencing issues, check if you have the latest version installed by running:
sudo pacman -Syu libinput

2. Adjust Touchpad Settings

You can customize your touchpad settings further to improve responsiveness. Below are some options you can tweak in your xorg.conf.d file:

  • Acceleration Profile: To adjust touchpad responsiveness, add or modify the following lines:
Option "AccelProfile" "adaptive"
Option "AccelSpeed" "0.5"  # Range from -1 to 1; 0 is neutral
  • Sensitivity: If the sensitivity seems off, you might also want to try adjusting the ConstantDeceleration option:
Option "ConstantDeceleration" "2.5"  # Lower value for more sensitivity

3. Using synclient

If you decide to switch to the synaptics driver, you can use synclient for more granular control. Here's how to check your current settings and modify them:

  • Check current settings:
synclient -l
  • Set palm detection to avoid unwanted clicks when typing:
synclient PalmDetect=1
synclient PalmMinWidth=5
synclient PalmMinZ=50

Practical Examples

To practically implement the configurations discussed:

  1. Open a terminal.
  2. Edit your touchpad configuration file using your favorite text editor:
    sudo nano /etc/X11/xorg.conf.d/40-libinput.conf
  3. Paste and modify the settings as necessary based on the examples provided.
  4. Save and exit the editor.
  5. Restart your X session or reboot your system.

Additional Tips

  • Always create a backup of your configuration files before making any changes.
  • Testing different settings incrementally can help identify what works best for your specific touchpad sensitivity needs.
  • Consult the Arch Wiki for Touchpad Configuration for the latest updates and community advice.

Conclusion

Improving touchpad responsiveness on your 2022 Dell XPS 15 running Arch Linux doesn't have to be a daunting task. By adjusting your driver settings and fine-tuning the configuration file, you can achieve smoother and more precise touchpad movements.
