The decimals ‘0.999…’ and ‘1’ refer to the real numbers that are equivalence classes of Cauchy sequences of rational numbers (0.9, 0.99, 0.999,…) and (1, 1, 1,…) with respect to the relation R: (aRb) <=> (lim(a_n-b_n) as n->inf, where a_n and b_n are the nth elements of sequences a and b, respectively).

For a = (1, 1, 1,…) and b = (0.9, 0.99, 0.999,…) we have lim(a_n-b_n) as n->inf = lim(1-sum(9/10^k) for k from 1 to n) as n->inf = lim(1/10^n) as n->inf = 0. That means that (1, 1, 1,…)R(0.9, 0.99, 0.999,…), i.e. that these sequences belong to the same equivalence class of Cauchy sequences of rational numbers with respect to R. In other words, the decimals ‘0.999…’ and ‘1’ refer to the same real number. QED.

Good bot.

I ran $ curl -s "https://archlinux.org/mirrorlist/?country=FR&country=GB&protocol=https&use_mirror_status=on" | sed -e 's/^#Server/Server/' -e '/^#/d' | rankmirrors -n 5 -. Where should I see an option to update to KDE 6.1?

Yeah, I was trying to do stuff like sudo install. I was not aware that it is used in combination with other commands like that.

I was wondering what I was doing wrong with sudo.

Try Settings > Window Management > Desktop Effects > “Windows Management” section > Overview and configure it

The problem is that there is no such option there, which is why I’m asking.

It seems that I need to install kdeplasma-addons. I will need to look into how people usually use pacman, as it keeps asking me to login as root.

Exactly

Didn’t work.

Read my other comment. Maybe this is the breeze setting that does not have any way to change layout at the logging screen

This issue seems to be resolved now, but the only layouts that I can switch between are the ones I manually set in the settings of the OS after I managed to change the login screen to a different one that allowed me to input the password in English.

This is weird, considering that on the previous installation, without having to manually set multiple layouts, I was able to switch between different layouts, but only outside of the ‘bad’ login screen. For clarity: the ‘bad’ login screen currently does allow me to switch between different layouts.

Also, in case you wouldn’t mind helping me with this other thing that is outside the scope of the initial complaint: where do I find the KDE cube options? It doesn’t seem to be in the Window management options, nor do I see a downloadable version of the such. The KDE plasma version is 6.0.5.

It seems like VirtualBox doesn’t automatic removed the iso file from the boot options. Try change this configuration at the VirtualBox and select the boot to be at the virtual driver

Not sure what you are suggesting, but it seems that the hard drive is the last active option in the boot order for that VM. I assume you are suggesting to make it the priority boot device?

At the archinstall script you must’ve set the root password, right?

I did, and I remember it.

At the SDDM login screen, you must press Ctrl+Alt+F3 to enter the TTY3 (a big whole full screen terminal) asking for a login. Type root, press enter and then it will ask for your password

Alright, I did that and run the command.

I still don’t know how to switch between the keyboard layouts, and with this installation I opted for the US keyboard layout to be the default one, but have since added one more layout to the list. I couldn’t place the keyboard layout widget for some reason, and there is no indication of what layout is chosen on the SDDM screen at all.

Right now, the user is blocked due to too many attempts to enter password, so I will have to wait.

What happened?

I don’t know beyond the fact that only Grub got installed and, apparently, nothing else. Upon starting the virtual machine, I was still offered to boot into the Arch installation environment. I have run archinstall again to make an installation without Grub, and am running an installation on a clone of that virtual machine where I have opted into using Grub.

Are you familiar with the syntax of Linux commands?

Depends on what you mean. I am not a frequent CLI user in general.

Currently, I am not sure how I am supposed to login as root.

EDIT: also, Ctrl+Alt+F2 just produces a black screen. Ctrl+Alt+F1 works, but the other problem persists.

EDIT 2: I still do not know how to switch between keyboard layouts in SDDM, and I can’t find information regarding that.

I did exactly the same thing yesterday and had the same issue. However I found the solution adding the keyboard layout to the X11 as well, with the command

Where do I input that command?

You must change the “br abnt2” to your keyboard layout, however

To which one? What is the format supposed to be for, for example, English, Putonghua, Norwegian, and Russian layouts?

Also, pay attention because there is a bug at the sddm login screen that doesn’t show the correct keyboard layout until you start typing, so don’t worry if at the beginning is “US”

The problem is that it is initially not the US English one, while the password is in English.

Apologies if I sound rude. I am currently frustrated regarding this process. Another installation failed for no discernable reason despite no errors occurring as a result of archinstall. (EDIT: Grub did get installed, but not anything else, apparently.)

EDIT: also, I still don’t know how to switch keyboard layouts in SDDM.

That’s literally just regular liberalism but ‘there should be some co-ops!’ I.e., it’s just liberalism.
