This tutorial shows how to turn off your laptop’s built-in display for using external monitors in Ubuntu Desktop.<\/p>\n

When working with multiple monitors, it can be useful to disable the built-in screen for saving power. You can set lid close action to do nothing then just close the laptop lid.<\/p>\n

However, the lid close action may not work properly in some laptops, or you need to use the built-in keyboard and touch-pad. In the cases, here are a few other ways to do the job.
\n<\/p>\n

Method 1: Use System Settings<\/h3>\n

If you have only one external monitor connected, and want to use that one instead of the built-in display, then Gnome Control Center (aka, System Settings) has the option to do the job under Displays<\/i> panel.<\/p>\n

First, open Settings<\/b> from either top-right corner system status menu or ‘Show Applications’ screen.<\/p>\n

\"\"<\/a><\/p>\n

When it opens, navigate to “Displays<\/b>” in left.\u00a0 (For Ubuntu 22.04<\/strong>) Then, click Single Display<\/b> under Display Mode settings. Finally, click to choose any one of the monitors for use. All others will be turned off, once you clicked on “Apply<\/b>” button.<\/p>\n

\"\"<\/a><\/p>\n

For Ubuntu 24.04<\/b>, go to Settings -> Displays<\/b>, then choose the display you want to turn off in right to go to its individual settings page. Finally, turn off the toggle switch to disable it.<\/p>\n

\"\"<\/a><\/p>\n

Other Desktops, such as MATE and XFCE, also have options to turn off connected monitors, just open “Displays” settings dialog for the toggle option.<\/p>\n

Method 2: Use Kernel parameter to disable monitor on startup<\/h3>\n

If the built-in display is broken, or you rarely use it, there’s a kernel parameter to disable it on system startup. This can be useful when you have more than one external monitors connected, and want to use them while leaving only the built-in one turned off.<\/p>\n

NOTE: After applied this method, your laptop built-in screen will be turn off automatically on every boot after Grub boot-menu. To restore, either connect an external monitor, and undo the changes, or when boot into Grub boot-menu, press ‘e’ and delete the kernel parameter, then undo changes after boot-up.<\/p>\n

1. Find out the device name of connected monitors<\/h4>\n

First, press Ctrl+Alt+T<\/code> on keyboard to open terminal. When terminal opens, run command to tell your monitor device names:<\/p>\n
