... 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.

@kde Yo, application snapshots? Switching DEs within seconds? What is this sorcery?

Really though, I can already think of a certain handheld gaming PC that would really benefit from saving and restoring the state of applications to and from disk, both in a gaming context and for more seamless switching between gaming and desktop modes.

@Bright5park @kde

Not only switching desktops in seconds, but you take all your open windows with you, all the graphical applications in the exact same state they were on the other desktop!

@Bro666 @kde That will be a really great power-saving measure for Linux phones in particular.
Application has been sitting there, doing nothing for a while? Instead of just closing it, just commit the state to disk, and put a marker somewhere to signify that the app should be restored on next launch.

...actually... if two systems are close enough in terms of installed packages, kernel and package versions and hardware, I wonder if you could transfer the state of an application between them.

@kde Amazing.

Is wayland reconnection implemented in GTK4?

@kde I see

Not only does this technique work here, but we have pending patches for GTK, SDL and even XWayland, with key parts of SDL merged but disabled already.

But I can't search it in GTK issue tracker.

@kde this opens up great possibilities, thrilled for the future (power saving possibilities, seamless movement between devices, switching DEs/WMs…)

@kde I’m 100 per cent sold on #Gnome but I really love to see this! And I hope KDE and Gnome will work even closer together in the future.

@kde checkpoint restore would be a godsend for debugging issues that are hard to reproduce!

Much more useful than "send me the logs" and praying that logging has sufficient details.
