To be more specific, the Steam client should listen for several different FreeDesktop.org events:
Sleep mode (Monitor or system)
Screensaver
Screen lock
Additionally it should listen for the events that specify inhibitors blocking the screensaver, lock-screen and screen sleep functions to detect when the timer auto-away should be disabled. This would allow enabling the timer auto-away as well for desktops that don't properly announce their screensaver and screenlock functions.
I understand that this is a complete rewrite of the auto-away function, but it should create a modern auto-away function that works well on any desktop.
As a note, suspending the HTML Renderer when minimized and setting it to clear it's memory on memory pressure events should reduce background footprint. It might be a good idea to add as well. The threads should probably sleep and remain ready to run unless they need to be evacuated from a second memory pressure event (after non-essential data is removed from the first event.) If you wish I can make a second idea report for this. "Better suspend functionality for GUI client." Or you can do it yourself after brainstorming more ideas on how to implement it.

Please describe your issue in as much detail as possible:
When away from the system and the screen locks, my system does not go into away mode.
Note: I rely on only the screenlock and monitor power save in KDE, not the screensaver. I have no need for power-wasting eye candy.
Steps for reproducing this issue:
The Steam client should use FreeDesktop.org api to detect screen locking and use that to determine auto-away.
It might also be beneficial for the client to self-hide in this state and pause all rendering processes to save on processor usage.
