Ubuntu Server 13.10 now goes to sleep when closing laptop lid

I recently upgraded to the latest version (13.10). I have it running on an old laptop. Since the upgrade, whenever I close the laptop lid, it goes to sleep mode.

Any idea on how to fix?

I've tried the solution here:

Keep Ubuntu Server running on a laptop with the lid closed?

After installing acpi-support I don't have the file: /etc/acpi/event/lidbtn to edit.

Your help is appreciated!

Solution 1:

I've had the same problem and after a lot of reading, I realized that Ubuntu 13.10 uses systemd-logind and it handles the lid close event. To disable entering the sleep mode edit the /etc/systemd/logind.conf file and uncomment/modify/add the line:

HandleLidSwitch=ignore

Then execute sudo restart systemd-logind or simply reboot.

This has solved the problem on my PC.

Update for 15.04

I'm not sure if Ubuntu 15.04 already switched to systemd completely. If so, the new command for restarting the service is sudo systemctl restart systemd-logind.service.
