From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[Solved] How to permanently disable "resume from suspend" when opening lid? (lemmy.ca)

Edit: Thanks for all suggestion! In my case (Thinkpad) I managed to make it persistent via udev, as described here.

It looks like there was a pre-existing udev configuration about this, but had slightly wrong SUBSYSTEM and DRIVER parameters:

old: SUBSYSTEM=="acpi", DRIVER=="button"
correct (in my case): SUBSYSTEM=="platform", DRIVER=="acpi-button"

maybe because of some recent systemd changes?

Hope this may help others.

I have Kubuntu on a Thinkpad, and a S3-sleep state selected in the Bios.

My setup has always been to not resume from sleep when the lid is open. I achieved this by running once

echo "LID" | sudo tee /proc/acpi/wakeup

which toggles the wakeup-on-lid state. The behaviour would be respected upon restart.

Here's my problem: since some recent update – I don't know whether from apt or fwupd – I discovered that the laptop was waking up upon lid opening. So I issued the command above again. It works, but it gets reset upon restart, unlike before.

Anyone has good tips on how to make this setting permanent?

In the Bios I didn't find any settings about this.

Cheers!

Reading the arch wiki (a great resource regardless of your distro) suggests this is a bug (though where, it does not say). The easiest "fix" would probably be a systemd unit that does echo "LID" > /proc/acpi/wakeup on boot, as suggested in the linked troubleshooting.

You could add a simple startup script that just issues this command when the system is booted.
