Hi Martin,

Okay, i see. Thanks for the hint!

I tried to find the relevant source code which is responsible for the screen locking, but I just skipped over the code. My bet would be screenShiels.js and some calls to a thing called loginManager? But what component exactly is initiating the dpms command? I didn't found it in the gnome-shell source code :-(

It is in the power plugin of gnome-settings-deamon
