I use xss-lock, which I recently added to Nixpkgs.  I start
xss-lock from .i3/config, but presumably it would work in
displayManager.sessionCommands as well.  xss-lock uses xset to
to both configure the screensaver delay as well as to manually
start the screensaver (if you want to activate the screensaver
with a hotkey, for example).

One of my favorite features of xss-lock is that it knows about
suspend/resume and will automatically lock the screen on resume.

Here is the relevant section from my .i3/config file:

    # Win+L locks the screen.
    bindsym Mod4+l exec xset s activate

    # Start xss-lock (and lock the screen after 15 minutes)
    exec_always xset s 900
    exec_always --no-startup-id xss-lock -- i3lock -n -i $HOME/example.png

Let me know if you need any additional information.
