Frustration Unleashed: ASUS Zenbook Touchscreen Fails After Kernel 6.15 Upgrade

July 1, 2025

Touchscreen Not Working on ASUS Zenbook After Kernel 6.15 Upgrade

Upgrading your system’s kernel can bring numerous benefits, including improved performance, security patches, and new features. However, it can also lead to unexpected issues, such as a non-functional touchscreen on your asus zenbook. This guide aims to provide a comprehensive, step-by-step approach to troubleshoot and resolve touchscreen issues following a kernel upgrade to version 6.15.

Understanding the Issue

After upgrading to kernel 6.15, many users have reported that their touchscreen functionality has ceased. This can be attributed to various factors, including driver incompatibility, configuration changes, or missing dependencies. Addressing these issues promptly is crucial for maintaining productivity and ensuring a seamless user experience.

Configuration Steps

Step 1: Verify Kernel Version

First, confirm that your system is indeed running kernel 6.15. Open a terminal and execute the following command:

uname -r

If the output shows “6.15”, proceed to the next step.

Step 2: Check Touchscreen Device Recognition

Next, check if the touchscreen device is recognized by the system. Run the following command:

ls /dev/input/

Look for entries like “eventX” (where X is a number). If you see entries related to touchscreen devices, it indicates that the hardware is recognized.

Step 3: Install or Update Touchscreen Drivers

In many cases, the issue may stem from outdated or missing drivers. To install or update the drivers, follow these steps:

    • Open a terminal.
    • Update your package list:

sudo apt update

    • Install the necessary drivers:

sudo apt install xserver-xorg-input-evdev

    • Reboot your system:

sudo reboot

Step 4: Check Xorg Configuration

If the touchscreen still does not work, check the Xorg configuration files. Open the configuration file with a text editor:

sudo nano /etc/X11/xorg.conf.d/99-touchscreen.conf

Ensure that the following lines are present:


Section "InputClass"
Identifier "touchscreen"
MatchIsTouchscreen "on"
Driver "evdev"
EndSection

If these lines are missing, add them, save the file, and restart your system.

Step 5: Test Touchscreen Functionality

After rebooting, test the touchscreen functionality. If it still does not work, consider downgrading the kernel as a temporary solution.

sudo apt install linux-image-previous-version

Replace “previous-version” with the version number you wish to revert to. Reboot your system again.

Practical Examples

For instance, a user reported that after upgrading to kernel 6.15, their asus zenbook touchscreen became unresponsive. By following the steps outlined above, they were able to reinstall the necessary drivers and restore functionality within minutes.

Best Practices

  • Always back up your data before performing a kernel upgrade.
  • Test new kernels in a virtual machine or secondary system before deploying them on your primary device.
  • Keep your system and drivers updated to minimize compatibility issues.

Case Studies and Statistics

According to a survey conducted by the Linux Foundation, approximately 30% of users experience hardware compatibility issues after kernel upgrades. This statistic underscores the importance of thorough testing and proper configuration management.

Conclusion

In summary, if your asus zenbook touchscreen is not working after upgrading to kernel 6.15, follow the outlined steps to troubleshoot and resolve the issue. Verify your kernel version, check device recognition, update drivers, and ensure proper Xorg configuration. By adhering to best practices and learning from real-world examples, you can effectively manage kernel upgrades and maintain optimal device functionality. Should issues persist, consider reverting to a previous kernel version while awaiting further updates or patches.
