How to Disable the Touchscreen on Your Chromebook (2023 Guide)
Touchscreens can be incredibly convenient, allowing you to tap, swipe and interact with your device in intuitive ways. However, there are times you may want to turn the touchscreen off on your Chromebook. Maybe you keep accidentally brushing the screen while typing, or a malfunctioning digitizer is registering "ghost" touches. Parents may also want to disable the touchscreen to stop small children from grabbing at the display.
Unfortunately, there is no simple "off switch" for the touchscreen buried in the ChromeOS settings. Google doesn‘t provide an easy way to do it. However, with a little know-how, we can work around this limitation. In this guide, I‘ll walk you through the step-by-step process to toggle your Chromebook‘s touchscreen on ChromeOS. We‘ll be enabling an experimental feature and using a special keyboard shortcut. Don‘t worry – I‘ll explain everything! Let‘s get started.
Why isn‘t there an easy way to disable the touchscreen?
You might be wondering – why doesn‘t Google include a simple on/off toggle for the touchscreen in the ChromeOS settings? It seems like an obvious feature. The answer comes down to how the touchscreen digitizer hardware works in conjunction with the software.
When you tap on a touchscreen, an electrical circuit is completed at the point of contact, allowing the digitizer to calculate the precise position of your finger. This raw touchpoint data is then passed to the operating system‘s device driver to be processed and translated into a "touch event" the software can understand.
Disabling the touchscreen isn‘t as easy as just telling the OS to ignore these touch events. The digitizer keeps sending the raw data. The OS has to actively process it, even if it then discards the resulting touch events. There‘s no way to just flip a switch and have the digitizer stop detecting touches altogether at a hardware level.
The only way to really prevent the digitizer from registering touches is to physically disconnect it from the motherboard. This isn‘t practical for most users. Opening up the device to unplug the digitizer could damage the delicate internal components and would definitely void your warranty!
Since Google can‘t provide an easy software-level "off switch" for the touchscreen without a major low-level rearchitecting of the OS touch input processing pipeline, they‘ve hidden the feature behind a developer-focused workaround as we‘ll see in the next section. It‘s not ideal, but it gets the job done.
The 4-Step Process to Turn Off the Touchscreen on ChromeOS
Alright, let‘s walk through the process step-by-step:
- Open the Chrome browser and type chrome://flags into the address bar, then press Enter. This will open the experimental flags settings page.
- In the search box at the top of the page, type in "debugging keyboard". This will surface the "Debugging keyboard shortcuts" flag we need.
- Click the drop-down menu next to the flag and change it from "Default" to "Enabled".
- Click the "Restart Now" button at the bottom of the screen to reboot your Chromebook and apply the flag change.
- Once your Chromebook finishes restarting, you can toggle the touchscreen on and off at any time by pressing Shift+Search+T. The Search key has a magnifying glass icon and is located on the top row of the keyboard where Caps Lock normally resides.
That‘s it! Your touchscreen is now disabled. If you want to re-enable it, just press Shift+Search+T again. You can toggle it on and off as much as you like. If you ever want to remove the debugging keyboard shortcuts flag, just go back to the chrome://flags page, find the flag, switch it back to "Default" and restart.
Here‘s a quick video walking through the whole process:

Note that these steps will work on any Chromebook, but the exact layout of the flags page and wording of the debugging flag may change over time as Google tweaks things. The keyboard shortcut should remain the same though.
Understanding Chrome Flags
In the steps above, we enabled something called a "Chrome flag" to access the touchscreen toggle shortcut. But what exactly is a flag? Let me explain.
ChromeOS is based on the open-source Chromium project. Google and other developers are constantly experimenting with new features and tweaks to improve the OS. But new code can introduce bugs and stability issues. To mitigate this, Google hides work-in-progress features behind "flags" – special settings that are disabled by default.
Developers, early adopters and curious tinkerers can go to the chrome://flags page to see all the experimental features currently in development and enable or disable them at will. It‘s a way for Google to test out new ideas and get feedback from real-world usage without affecting the average user. The company can see which flags are popular and refine the promising ones to eventually graduate into a standard part of ChromeOS. In fact, many of the features you enjoy today, like picture-in-picture video, started life as a humble Chrome flag!
Some of the flags, like our debugging keyboard shortcuts, aren‘t ever meant to become regular user-facing features. They exist to make life easier for developers and power users. There are flags to emulate different device types, simulate network conditions, and access deep system diagnostics.
Of course, the experimental nature of flags means they can be unstable. Enabling too many at once can cause unexpected bugs, performance hitches, or even crash your Chromebook entirely! They may also change or disappear over time as the codebase evolves. Google even puts a big warning on the flags page not to enable anything unless you know what you‘re doing!
For the most part the flags are safe to play with if you‘re careful. But I wouldn‘t enable any on a mission-critical device or if you aren‘t comfortable troubleshooting your way out of a jam. It‘s wise to back up anything important before you go flipping switches. If something does go wrong, you can always do a powerwash to reset your Chromebook back to its factory settings.
Other Useful Chrome Flags to Try
While you‘re on the flags page, you might see some other experiments that sound intriguing. There are a ton of cool ones in there! Over the years, some of the most popular flags have included:
- Reader Mode: Strips out extra page elements like ads and formatting to present a cleaner, more readable view of articles.
- Tab Groups: Allows you to organize your browser tabs into collapsible groups for better tab management and less clutter.
- Smooth Scrolling: Makes the animation of scrolling up and down pages more fluid and polished to improve the visual experience.
- Parallel Downloading: Lets ChromeOS download different parts of a file simultaneously to speed up download times.
- Password Leak Detection: Automatically checks your saved passwords against known data breaches to keep your accounts secure.
- Enable Stylus Tools: Adds extra options and tools for stylus/pen input on touchscreen Chromebooks that support it.
Of course, you may find that a particular flag doesn‘t work well for your needs or introduces an annoying bug on your specific device, but that‘s what the "Reset all" button is for! Feel free to experiment and see what hidden gems you discover.
Alternative Touchscreen Fixes
If your main issue with the touchscreen is accidental inputs while typing, disabling it entirely may be overkill. Here are a couple other solutions to try first:
-
Recalibrate the touchscreen – Over time, the digitizer and display can fall out of alignment causing touch input to be interpreted incorrectly. Most Chromebooks have a touchscreen calibration tool built-in. With the debugging keyboard shortcuts flag enabled, press Ctrl+Shift+T to launch it. Follow the on-screen prompts to re-align the touchscreen targeting. This can make a too-sensitive screen much more precise and reduce accidental touches.
-
Use a stylus or touchscreen gloves – One source of accidental input is when your palm or the side of your hand brushes the screen while typing on the keyboard. You can avoid this by using a stylus to interact with the touchscreen instead of your finger. This gives you finer control. Or, wear a pair of capacitive touchscreen gloves. These specially-designed gloves have conductive material sewn into the fingertips so you can retain the precision and convenience of finger touch, but the glove fabric prevents accidental input from your palms. As a bonus, they‘ll keep your hands warm too! You can find both styli and touchscreen gloves for cheap online.
If the problem is due to a hardware failure where the digitizer is registering phantom touches that aren‘t really occurring, you‘ll likely need to have your Chromebook serviced under warranty or take it in for repair. Disabling the touchscreen in that case is really just a band-aid, but at least it lets you keep using the device until you can get it fixed!
The process is a little different on Windows machines. There, you actually can disable the touchscreen driver itself to prevent Windows from processing touch input at all. To do it, open the Device Manager, find the listing for "HID-compliant touch screen", right-click it and choose "Disable device". Of course, this still doesn‘t disable the touchscreen digitizer at a hardware level, it just stops Windows from processing the resulting touch data into events. But the end result is effectively the same – no more touch input of any kind until you re-enable the device! Microsoft provides this as a standard option likely because Windows has to support a huge range of manufacturer-specific touchscreen hardware and drivers. It‘s more of a necessity for troubleshooting. With ChromeOS, Google has full control over the driver stack so they can manage it server-side and don‘t provide a user-accessible kill switch.
Summary
To recap, here‘s how to disable the touchscreen on a Chromebook:
- Open Chrome and go to chrome://flags
- Enable the "Debugging keyboard shortcuts" flag
- Reboot your Chromebook
- Press Shift+Search+T to toggle the touchscreen on and off
Chrome flags give you access to experimental features, but can negatively impact performance and stability, so enable them with care. If you just want to cut down on accidental touches, recalibrating the screen or using a stylus may be a better option than disabling the touchscreen entirely. But if you must turn it off completely, at least now you know how! Just remember to back up your data first before playing with flags. You never know what might go wrong. Happy experimenting!

FAQs
Q: Will this work on ChromeOS tablets?
A: Yes! ChromeOS tablets like the Pixel Slate don‘t have a physical keyboard, so you may need to connect a USB or Bluetooth keyboard to use the Shift+Search+T shortcut. But the rest of the process is the same.
Q: Can I disable the touchscreen on a regular laptop that has one?
A: If it‘s a Chromebook, yes. For Windows laptops, you can disable the touchscreen through the Device Manager as mentioned above. Macs don‘t support touchscreens at all currently.
Q: Is there a way to schedule the touchscreen to turn off and on at certain times?
A: Not easily. You‘d have to create a script that sends the simulated Shift+Search+T keypress and run it on a schedule using a Chrome extension or other automation tool. Probably more trouble than it‘s worth.
Q: What if I forget the keyboard shortcut?
A: You can always go back to chrome://flags, search for "debugging keyboard shortcuts" and view the list of available key combos there.
Q: Will my touchscreen still work if I plug in an external monitor?
A: It should! ChromeOS will detect and configure the touchscreen even if you‘re not actively using the built-in display. The keyboard shortcut will toggle it on both screens.
Q: Help! I engaged the touchscreen toggle shortcut and then forgot about it. Now my touchscreen doesn‘t work!
A: Don‘t panic! You probably just left the touchscreen disabled by accident. Press Shift+Search+T again to re-enable it and you should be good to go. If that doesn‘t work, try recalibrating it with Ctrl+Shift+T or doing a hard reboot of your Chromebook.
