Yes, for now someone has to be logged in and have the server running

To maybe prevent a catastrophe: The system is not able to restore virtual desktop assignments yet, it only starts the apps you had open before.

Just click the button in the sddm settings page

There have been incidents involving malicious code downloaded through Plasma global themes.

No malicious code was involved, just buggy code.

That's just a law of computers, the default arrangement of monitors must always be wrong.

You can just sync your Plasma settings to SDDM though, and it'll use the same output settings as your session

KDE did bother, this does neither happen with KScreenlocker, nor do non-screenlocker windows show in another way, because the screen locker is integrated with the compositor.

If the compositor crashes or gets disabled somehow ofc though, that integration doesn't help either and you have to rely on a mountain of bad hacks as well as the hope that the screen locker doesn't also crash for nothing to happen in that case, but it's as close to secure screen locking as you get on Xorg... in the end the solution for secure screen locking is still Wayland.

Fedora just has

polkit.addRule(function(action, subject) {
    if ((action.id == "org.freedesktop.packagekit.package-install" ||
         action.id == "org.freedesktop.packagekit.package-remove") &&
        subject.active == true && subject.local == true &&
        subject.isInGroup("wheel")) {
            return polkit.Result.YES;
    }
});

in /usr/share/polkit-1/rules.d/org.freedesktop.packagekit.rules. If you put the same file in there, it should work.

Yes, and many distros have a polkit rule set up to allow installing or updating without a password. You can likely just copy it from Fedora or sth

Writing graphics code in a unified model is quite a bit different from the conventional x86 model.

It isn't. The difference is pretty small, and it's just optimizations for when copies can be skipped and not a radical change in the approach of how rendering is done.

Intel would need their own equivalent to Metal if they wanted to do a similar move.

Not at all. If big-ish changes were required, they could be exposed as Vulkan extensions.

I don’t know enough about Vulkan to say if it’s compatible with this kind of approach

Of course Vulkan, the graphics API used on all modern phones except Apple's, supports using integrated graphics efficiently.

S3 is standby. Hibernate is S4

the fact that 1.8 was working tells me that it is possible for a window manager to work well for nvidia

Nope, it's a race condition for which the visible effects can appear or disappear for plenty of reasons. The only fix is explicit sync, which is being worked on for wlroots

It's been possible for a long time, but yes, now you can do it intuitively in the shortcuts GUI
