This guide outlines the steps to disable your Ubuntu device’s touchscreen, ideal for resolving issues or enabling mouse-and-keyboard preference.
Find Your Touchscreen ID
Start by opening a terminal (Ctrl+Alt+T). Enter the command xinput list and press Enter. This displays all input devices on your system.
Locate the entry resembling your touchscreen (e.g., “Synaptics Touchscreen” or “ELAN Touchscreen” ). Jot down the associated ID number.

Disable Your Touchscreen
With the touchscreen ID noted, run the following command in your terminal, replacing <device-id> with the actual number:
xinput disable <device-id>
This command directly disables the specified input device, in this case, your touchscreen.
Lasting Touchscreen Disable
The previous steps temporarily disable the touchscreen. For permanence, create a startup script:
- Open Terminal: Press Ctrl+Alt+T.
- Create Script: Run sudo nano /etc/X11/Xsession.d/99-disable-touchscreen.sh (enter password). This opens a text editor with admin rights.
- Add Script Content: Paste the following, replacing <device-id> with your touchscreen ID:
#!/bin/bash
xinput disable <device-id>
- Save & Exit: Press Ctrl+O, then Ctrl+X.
- Make Executable: Run sudo chmod +x /etc/X11/Xsession.d/99-disable-touchscreen.sh.
Your touchscreen will now be disabled on every boot.
Remember: Replace <device-id> accurately to ensure the correct device is disabled.
