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.

I have an older laptop so no need to worry about the stupid Modern Standby introduced in late 2019. What I want is a reliable way to lock screen when suspend, doesnt matter how bloat or minimal.

First, to make sure the laptop suspends when I close the lid:

on some Distro, this works OOTB.
If it doesnt, I check /etc/systemd/sleep.conf and set allow Suspend from there.

After this, laptop does suspend. Now here comes the trickiest part, how to make sure your screen stays locked? There are so many rabbit holes so I want some help.

Depending on your software selections, you can fall into 3 categories:

create some systemd script like this: https://wiki.archlinux.org/title/Slock

Problem: sometimes the screen doesnt get locked, i.e. your slock doesnt get triggered. Even worse, in some cases, the desktop is briefly shown on resume, before the locker shows up.

use program like xss-lock, xautolock. Then links it with your locker and then autostart in your wm. Eg: i3wm with i3lock and xss-lock:

exec --no-startup-id xss-lock --transfer-sleep-lock -- i3lock

This works. But the laptop sometimes takes a while to suspend.

manually invoke "Lock" with a keystroke. Then close the lid. Apparently this works but I have to remember to manually "lock" every single time.

Thanks for any suggestions.

I have used xss-lock with i3lock in the past with success. It makes sure that systemd-logind notifies over dbus when entering hibernation so that xss-lock starts the configured lockscreen.

Before that I had a script which locks manually and then calls systemctl hibernate.

Currently I am on Gnome, but I want to transition back to a more minimalistic DE like niri. Then I have to look on the options again to reliably lock my screen.
