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

Just click the button in the sddm settings page

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

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

Just use Wayland, then you don’t have to care about this

Setting the speed to the max does turn them off

The only effects relevant for performance are blur and background contrast. Turn those off if you feel the system is slow, maybe increase the animation speed and you’re done

You can probably implement it in the script itself, but there’s no external functionality to do it

I was especially surprised to find that Gnome would turn the screen around correctly by itself. With KDE Plasma I had to set the correct screen orientation myself. And unfortunately Plasma also did not come with any on screen keyboard so it was effectively unusable.

You just need to use a distro that follows our upstream defaults - namely Wayland, and having the virtual keyboard Maliit installed by default - then everything will work out of the box with KDE Plasma too.

I’m one of the KWin maintainers, I can tell you with absolute certainty that this hasn’t changed. Maybe you were on Xorg then?

No, they were always global. Scrolling on the desktop to change virtual desktops was disabled by default, but nothing changed about the three finger gestures

It was already a pain that one could not personalize these actions, but at least the defaults were ok for me (3 finger up/down for desktop grid/present windows). And I could use fusuma for more.
The new defaults hijacks all 3-finger gestures to scroll one virtual desktop up/down left/right which I find useless.

You don’t remember the gestures on Plasma 5 correctly. They already used both 3 and 4 finger gestures like they do now, and 3 finger gestures were for virtual desktop switching too.

I don’t know tbh, I see neither any MR that removed it, nor the option you’re talking about.

What you want is now a built in option, you can set the screen saver timeout for when the screen is locked separately from the normal timeout

Yes, it is a KDE shortcut, a kwin_x11 shortcut to be more specific. It’s not a thing with kwin_wayland, and so it most certainly did not help or do anything for you - unless you’re not actually using the Wayland session of course.

That shortcut does nothing on Wayland. What you’re experiencing is either placebo, or you’re not using Wayland

wasn’t it thought for kiosk applications, then extended to login screens

No, that’s a really pervasive myth, spread by trolls.

Wayland - or rather, Weston - first came into use in the embedded scene because things are a lot simpler to change there and the limitations of Xorg even more unforgiving… But it was never designed for that purpose alone, it was always meant to replace Xorg everywhere.

It is repeated in every single damn “Linux phone” thread, and in every single thread an answer like this is needed: No, it fucking isn’t. You know exactly what everyone means, stop being a dick about it.

Yes, though it’s not exactly relevant to your wishes… KWin has supported VRR for almost three years now, and HDR for 9 months too (not released yet ofc). I’ve been playing all my HDR capable games in HDR mode for the past few months.

For me, this is more about making it more efficient and make it work better by default.
