Troubleshooting Touchscreen Issues
If your touchscreen is malfunctioning, disabling it can be a temporary workaround while you troubleshoot the problem. This allows you to continue using your Chromebook with a mouse and keyboard until you can resolve the underlying issue.
Methods to Disable the Touchscreen on Your Dell Chromebook
Several methods can be used to disable the touchscreen on your Dell Chromebook. We’ll explore the most effective and accessible approaches.
Using Chrome Flags: An Experimental Approach
Chrome Flags are experimental features that Google offers for testing and development purposes. They allow you to customize your Chrome experience beyond the standard settings. While not officially supported, they often provide useful options, including the ability to disable the touchscreen. It’s important to note that Chrome Flags are subject to change or removal without notice, so this method may not be permanent.
Accessing Chrome Flags
To access Chrome Flags, open a new tab in your Chrome browser and type chrome://flags in the address bar. Press Enter, and you’ll be presented with a page containing a long list of experimental features.
Searching for the Touchscreen Flag
In the search bar at the top of the Chrome Flags page, type “touchscreen.” This will filter the list and highlight the relevant flag. Look for a flag specifically related to disabling or enabling the touchscreen. The exact wording of the flag may vary depending on your Chrome OS version. Common variations include “Disable touchscreen” or “Touchscreen support.”
Disabling the Touchscreen Flag
Once you’ve located the appropriate flag, you’ll see a dropdown menu next to it. The default setting is usually “Default” or “Enabled.” Click the dropdown menu and select “Disabled.”
Restarting Your Chromebook
After disabling the flag, you’ll need to restart your Chromebook for the changes to take effect. At the bottom of the page, you’ll see a button labeled “Restart.” Click this button to reboot your device. Once your Chromebook restarts, the touchscreen should be disabled.
Re-enabling the Touchscreen
To re-enable the touchscreen, simply repeat the steps above, but this time, select “Enabled” or “Default” from the dropdown menu next to the touchscreen flag. Restart your Chromebook, and the touchscreen functionality will be restored.
Using Developer Mode and Command Line (Advanced)

Identifying the Touchscreen Device
In the Crosh terminal, type the following command and press Enter: xinput list
This command will display a list of input devices connected to your Chromebook. Look for the entry that corresponds to your touchscreen. It will typically be labeled something like “Synaptics Touchscreen” or “ELAN Touchscreen.” Note the “id=” number associated with the touchscreen device. This number is crucial for the next step.
Disabling the Touchscreen Using xinput
To disable the touchscreen, use the following command, replacing <id> with the actual ID number you found in the previous step: xinput disable <id>
For example, if the touchscreen ID is 10, the command would be: xinput disable 10
Press Enter to execute the command. The touchscreen should now be disabled.
Re-enabling the Touchscreen
To re-enable the touchscreen, use the following command, again replacing <id> with the touchscreen ID: xinput enable <id>
Press Enter to execute the command. The touchscreen will be re-enabled.
Making the Change Permanent (Optional)
The xinput command only disables the touchscreen for the current session. When you reboot your Chromebook, the touchscreen will be re-enabled. To make the change permanent, you can create a startup script that automatically executes the xinput disable <id> command every time your Chromebook boots. This involves more advanced Linux skills and is beyond the scope of this guide.
Exiting Developer Mode
If you decide you no longer want to use Developer Mode, you can exit it by rebooting your Chromebook. During the boot process, you’ll see a warning message about Developer Mode. Press the spacebar to initiate the process of disabling Developer Mode. This will erase all local data on your Chromebook and restore it to its original state.
Checking Accessibility Settings
While not a direct touchscreen disable, exploring accessibility settings may offer alternative solutions, especially if the issue is related to accidental touch inputs.
Accessing Accessibility Settings
Navigate to your Chromebook’s settings. This is usually done by clicking on the system tray in the bottom right corner of the screen and then selecting the gear icon.
Exploring Input Options
Within the settings menu, search for “accessibility” or navigate to the “Accessibility” section. Look for options related to mouse and touchpad settings. While there might not be a direct “disable touchscreen” option, you might find settings that reduce the sensitivity of the touchscreen or require a longer press to register a touch. These adjustments can help mitigate accidental touches.
Using On-Screen Keyboard Options
Some accessibility settings allow you to customize the on-screen keyboard. While this doesn’t disable the touchscreen, it can prevent accidental keyboard activations if the touchscreen is overly sensitive.
Troubleshooting Common Issues
Even after following the above methods, you might encounter some issues. Here are some common problems and their solutions.
Touchscreen Not Disabling After Using Chrome Flags
If the touchscreen doesn’t disable after using Chrome Flags, try the following:
- Double-check the flag: Ensure you’ve selected the correct flag and that it’s set to “Disabled.”
