設置Centos 8在筆記本電腦蓋上時的處理

1. Open the /etc/systemd/logind.conf file for editing.

2. Find the HandleLidSwitch=suspend line in the file. If it is quoted out with the # character at the start, unquote it.

   If the line is not present in the file, add it.

3. Replace the default suspend parameter with

   • lock for the screen to lock;

   • ignore for nothing to happen;

   • poweroff for the computer to switch off.

   For example:

   HandleLidSwitch=lock
   HandleLidSwitchExternalPower=lock

4. Save your changes and close the editor.

5. Run the following command so that your changes preserve the next restart of the system:

   # systemctl restart systemd-logind.service
