Phoronix: A Session Suspension & Restoration Protocol Proposed For Wayland

KDE Wayland developer Roman Gilg who started contributing to Wayland via last year's Google Summer of Code is proposing a new Wayland protocol for dealing with desktop session suspension and restoration...

Nice, just the other day I was told on Matrix/IRC that the X_SAVE_YOURSELF (or whatever it is called), along with ksmserver, had no replacement on Wayland.

I would like a few signals to ask apps to free memory, this would be useful to avoid swapping under memory pressure.

The nice thing is these protocols sometimes only need to be implemented in the toolkit or a few big applications to make a difference

What's the story with screen recording currently with Wayland? Is there now a standard way to do it?

What happened with the people whose only reply is "but Wayland is just a protocol" when you ask why it lacks features like this? Funny.

How about adding more useful features to the damn protocol instead of letting the compositor having free reign on them, which sucks incredibly.

This sounds silly. Just write a independent application/shell script that communicates with dbus to send the suspend/hibernate command to /sys/power/. Why even make a protocol for dbus of all things? The kernel handles all the events related to suspend/hibernate and I can suspend and restore several wayland desktops without any problems as of right now. Why fix what isn't broken?

What about reopening windows on next login after shutdown? (macOS does this)

What about letting programs close connections (e.g. IRC) cleanly before suspending?

Works on Gnome. https://help.gnome.org/users/gnome-h...record.html.en

Sorry man I was late.

but Wayland is just a protocol!

You know what is a "protocol extension" right?

It's an optional addition to the protocol. But is a standard. It's not a KDE-specific thing.
