It’s interesting because instead of “display manager” it should be “graphical login manager”, and the current “login manager” should be called “session manager”. I don’t know the origin of the name, though.

it can be skinned

and while we are at that, MPV also has a working reverse play implementation (though that’s like a slideshow), and it can very seamlessly do frame by frame playback, the hotkey of which just does normal playback perfectly while it’s long pressed

it literally has a lower CPU consumption, even when using hardware decoding. and even when playback is paused.

lower CPU consumption means more free resources for other programs, and lower power usage, which is more battery life.

it also seeks much smoother, I mean quicker with less delay

it tells you on a new tab. if you continue without restarting it you’ll see its already falling apart

sure, then already open programs will start malfunctining left and right, because they assume they have x version of files and libraries on a path, but in the meantime it has been replaced with version y. firefox and thunderbird are especially sensitive to it, but are not the only one.

unattended upgrades work fine on a server with relatively simple programs, but on the desktop world things are different.

it would be pretty useful if we could do this with the more popular distros, but I think we may be stuck with the way where you create an admin account for yourself for maintenance, and when you give the machine to them you make a new account for them too.

but I’m curious. how will you solve keeping the system up to date? Especially the web browser, but all the other things too

where you can just start the installer and it does everything for you, including users,

that sounds exactly what OP does not want? especially because they still habe to wait it over until the installation completes, before they can create the users and show them around the computer

what do you use x-eyes for?

it may be because of the browser’s user agent. Changing that may help, to make of believe that you are on an apple device
