Touchpad Reload

My Laptop often have an issue where touchpad stops responding after the laptop wakes up from sleep. This script will restart and make it work properly.

Tested Environment

• Laptop Model: HP ENVY X360
• Operating System: Zorin OS 17.3 Core

While tested on this specific setup, this solution might work for other laptops or Linux distributions experiencing similar touchpad issues after suspend, particularly those using the i2c_hid_acpi driver.

How It Works

The problem is that the touchpad's driver ( i2c_hid_acpi ) sometimes fails to load properly after the system resumes from a low-power state.

The touchpad-reload script fixes this by:

1. sudo rmmod i2c_hid_acpi: This command unloads the i2c_hid_acpi touchpad's driver from the system memory.
2. sudo modprobe i2c_hid_acpi: This command then loads the i2c_hid_acpi module back into memory, forcing it to re-load and properly detect your touchpad.

The script is placed in a special directory (/lib/systemd/system-sleep/) where systemd (system service manager) automatically runs scripts after a suspend/resume event. Making the script executable (sudo chmod +x) allows the system to run it as a program.

Installation

Follow these simple steps to install the touchpad fix:

1. Download the Script: Download the touchpad-reload file directly from this repository to your laptop (e.g., into your Downloads folder).

2. Open a Terminal: Press Ctrl + Alt + T or oopen your terminal.

3. Move the Script to the System Directory: Place the downloaded touchpad-reload file into the correct system directory (/lib/systemd/system-sleep/). Assuming the file is in your Downloads folder, use this command:

   sudo mv ~/Downloads/touchpad-reload /lib/systemd/system-sleep/

   You will be asked for root password.

4. Make the Script Executable: For the system to run the script, it must have executable permissions. In the terminal, run:

   sudo chmod +x /lib/systemd/system-sleep/touchpad-reload

5. Reboot Your System: It's recommended to reboot your laptop to ensure the script works properly. Simply type in the terminal:

   sudo reboot

   After rebooting, you're good to go!

6. Test the Fix (Optional): After rebooting and logging in, put your laptop to sleep. Then, wake it up. Your touchpad should now work as normal.

Uninstall

To remove the fix, simply delete the script file:

1. Open a Terminal: Ctrl + Alt + T
2. Delete the script:

   sudo rm /lib/systemd/system-sleep/touchpad-reload

   Enter your password and it gone!
