How to Keep Ubuntu 24.04 Laptop Running with Lid Closed

-
laptop lid closed and suspend

By default, Ubuntu suspends your laptop when you close the lid. However, in some use cases, such as downloading files overnight, using external displays, or running services, you may want your laptop to stay awake. Here’s how to configure your system so it continues running even with the lid closed.

Step 1: Edit the logind.conf File

Open a terminal and run the following command to edit the systemd logind configuration file:

sudo vi /etc/systemd/logind.conf

Find the following lines (they may be commented out) and modify them as shown below:

HandleLidSwitch=ignore
HandleLidSwitchExternalPower=ignore
HandleLidSwitchDocked=ignore

If any of these lines are commented out with #, be sure to remove the comment symbol.

  • HandleLidSwitch=ignore: Prevents the system from suspending when the laptop lid is closed, regardless of whether it's on battery or AC power.
  • HandleLidSwitchExternalPower=ignore: Specifically ensures the system does not suspend when the lid is closed and the laptop is plugged into AC power.
  • HandleLidSwitchDocked=ignore: Prevents suspend when the laptop is docked (e.g., connected to an external display or docking station).

Step 2: Restart the Logind Service

After saving the file, apply the changes by restarting the systemd-logind service:

sudo systemctl restart systemd-logind

That’s it!

Your Ubuntu laptop will now keep running even when the lid is closed. Just be cautious about heat buildup if you leave your laptop running in a closed space like a backpack.

How to Set Up Vaultwarden (Bitwarden) on Synology NAS (Best Free Alternative to LastPass)

-
Image
Have you ever felt overwhelmed managing passwords for all your websites? I used to use the same password across multiple sites , which wasn’t secure. To manage them better, I started using LastPass for years. However, in 2019, they changed their pricing policy — now it’s free only for one device for 30 days, and you have to pay to use it across multiple devices . If you're looking for a powerful and free password manager, Vaultwarden is one of the best alternatives to LastPass. What is Vaultwarden? Vaultwarden (formerly known as Bitwarden_RS) is a lightweight, open-source implementation of the Bitwarden server API written in Rust . It is fully compatible with official Bitwarden clients and is ideal for low-resource environments. Example: On a Synology DS916+, Vaultwarden uses 0% CPU and only 64MB of memory while running. My Setup NAS Model : Synology DS916+ DSM Version : DSM 7.1-42661 Update 1 Docker Image : vaultwarden/server Ins...
