Developers do not look for reports on social media, so they will not see it and all it does is clutter up the feed.

Plasma developer David Edmundson demonstrates how a desktop using Wayland, Qt6 and KWin can recover from a catastrophic crash as if nothing had happened.

The same principles can be applied to jumping from one desktop environment to another, for example, from #Plasma to #Gnome...

... And can provide a way to save the state of an application to disk, stopping the app in its tracks and removing it from memory, so that later you can restore it just where you left off.

@[email protected] @[email protected] the future is now! I like how many cool technologies emerge from wayland

Th combination Wayland/KWin is killing it. We recently had Arjen Hiemstra showing how you can access a remote desktop:

Something that was seemingly destined to die with X11.

Compositor handoff to switch between desktops looks legendary! I super hope something like that becomes stable and officially supported somewhere, it would be so fun to use

@[email protected] @[email protected] is this the compositor handoff protocol? is that implemented by all major compositors already?

Holy fucking shit this is incredible

This is so cool, I can't wait for KDE plasma 6

[–] [email protected] 3 points 1 year ago

Hopefully there will be more support for this than just Qt6, especially for stuff like Firefox

@[email protected] @[email protected] From the article it seems more of a #Qt win for now (though it does mention patches for many others), but in any case that's neat.

Now it all just needs sane ways to interface from #CommonLisp.

I can't wait until this makes it to gnome

[–] [email protected] 1 points 1 year ago (1 children)

@[email protected] @[email protected] Very cool. Here’s hoping to see this in @gnome one day too.

PS. I’m sure you’re aware of it but, just in case, the window positions/dimensions appear to be lost on the restart. (An issue I have on GNOME too whenever it returns from suspend.)

Gloom OPPS I meant Gnome is a dirt word.

@kde @kde
> For X11 this was unfixable; clients relied on memory stored by the Xserver, they made synchronous calls that were expected to return values, and multiple clients talked to multple clients.

time for X11 bouncer, X11 is network transparent ✨

@[email protected] @[email protected] Enlightenment had this features for years. Not only on wayland but in xorg too.

Hoorah for Enlightenment then? 🤷
