I don't need to lock and then suspend. I only want to lock the screen with an image as background.
I found on AUR "alock".
It can be compiled without pam and seems to work like i need, also the colors are command line configurable.
I will stick to it, hoping it will compile under BSD also

Cool, if I had known about this, I would have said something.

This being said, we appreciate you finding this, it helps to have minimalistic software, the more the better, if possible tho.

I say we, for the above reason.

There is no source for i3lock in extra.git

This depends on what you desire, but there is another locking method, called slock and also this:

xautolock allows you to use slock to lock within a time frame of your choosing.

There might be other options, elsewhere on the web, albeit... YMMV.

Point being, is there something specific you want in a screen locker?

Also, was unaware till now... but slock can be used in combination with specific suspend options, if you need that.

One of which being zzz, otherwise, use uswsusp... btw, uswsusp, is called s3ram in the command name, go figure as to why...

enable username to use s3ram with doas and your set for both.

I still use this os on as many devices as I can, but I choose mostly to directly communicate with the devs when I feel the need.

Anywho, peace all, will talk to you all later!

i3lock -i ~/.config/screenlock/wallpaper.jpg

does not work.
Moving to ~/.config/screenlock/ and executing:

i3lock -i wallpaper.jpg

it works
