Encrypt whole system? (sh.itjust.works)

My laptop isn't under my supervision most of the time. And I'd hate it if someone were to steal my SSD, or whole laptop even, when I'm not around. Is there a way to encrypt everything, but still keep the device in sleep, and unclock it without much delay. It's a very slow laptop. So decryption on login isn't viable, takes too long. While booting up also takes forever, so it needs to be in a "safe" state when simply logged out. Maybe a way that's decrypt-on-demand?

I'm on Arch with KDE.

The template is supposed to be something that you put in your own systemd services. plasma-kwin_x11.service and plasma-kwin_wayland.service both already have it.

If I have to guess, it is probably a bug that will get fixed sometime in the future, meaning this is not a viable solution until then. Sorry for that.

Just as a last bit of troubleshooting, check if cat ~/.config/startkderc shows systemBoot = true. If it does not, run kwriteconfig6 --file startkderc --group General --key systemdBoot true. I doubt this will change much, but still worth trying.

If I get some free time, I will do some testing and let you know here

    cat ~/.config/startkderc returns systemdBoot=true. I'm guessing you made a typo and this is correct. In this case I guess it just doesn't work on KDE, my next idea is LUKS on /home and hibernating instead of sleeping. Or I always wanted to try a tiling window manager... hm

    systemdBoot is supposed to be true, not a typo. But yeah, I don't use plasma much so I don't really know how to solve the issue... Sorry for that!

    No problem, thanks for the help. Also I got news is that I don't have to trust anyone with my laptop, I can keep it by my side after all. Still it's a security mesure, that I didn't solve in time. fun fact: LUKS on /home only breaks KDE. I really don't want to give up kde tho, I put on sway, realised that I needed to memorise console commands to change my fking volumes, so no thank you. I got spoiled by sweet UIs. it's so comfortable that everything is at one place.
