Arch Linux - it's really not that complicated

This is a step by step installation documentation on how I install Arch Linux on my Dell XPS 13 (9370) - my primary work setup. This is quite opinionated (e.g. f2fs root partition) and not applicable on every machine out there. But perhaps a rough guideline on how to easily install Arch Linux nonetheless.

Overview

Please also consult the official Arch Linux Documentation.
The step by step instructions can also be found on my Github.

Enter BIOS with F2 and configure:

Boot from USB

Make sure to boot from USB using UEFI - this is required by systemd-boot!

Set desired keymap

loadkeys en_US-utf8

(Optional) Connect to wifi

wifi-menu

Once done it can take some seconds - confirm it worked using ping

ping 1.1.1.1

Sync clock

timedatectl set-ntp true

Create two partitions:

CAUTION Find the correct disk/partition names for yourself using lsblk. From here on I am using mine as an example. Do not blindly copy paste these, it might not work or you might destroy partitions you don't want to destroy.

cgdisk /dev/nvme0n1

(Optional) Install f2fs-tools

pacman -S f2fs-tools

Formatting and encyption

Boot partition

mkfs.fat -F32 /dev/nvme0n1p1

Root partition

cryptsetup luksFormat --type=luks2 /dev/nvme0n1p2

cryptsetup open /dev/nvme0n1p2 luks

(choose filesystem - assuming f2fs)

mkfs.f2fs -l luks /dev/mapper/luks

Mount root and boot partition

mount /dev/mapper/luks /mnt

mkdir -p /mnt/boot

mount /dev/nvme0n1p1 /mnt/boot

Change pacman mirror priority, move closer mirror to the top

vim /etc/pacman.d/mirrorlist

Install the base system plus a few extra packages

f2fs-tools is needed if you chose f2fs as your partition

With some recent XPS Laptops linux-zen seems to be working better, e.g. resolves screen flickering issues

pacstrap /mnt base linux linux-firmware zsh vim git sudo efibootmgr wpa_supplicant
dialog iw f2fs-tools

Generate fstab

genfstab -L /mnt >> /mnt/etc/fstab

Enter the new system

arch-chroot /mnt

Setup time

rm /etc/localtime

ln -s /usr/share/zoneinfo/Europe/Berlin /etc/localtime

hwclock --systohc

Generate required locales

vim /etc/locale.gen

locale-gen

Set desired locale

echo 'LANG=en_US.UTF-8' > /etc/locale.conf

Set desired keymap and font

echo 'KEYMAP=us' > /etc/vconsole.conf

Set the hostname

echo '<hostname>' > /etc/hostname

Add hostname to /etc/hosts:

vim /etc/hosts

127.0.0.1	localhost
::1		localhost
127.0.1.1	<hostname>.localdomain <hostname>

Set password for root

passwd

Add real user

useradd -m -g users -G wheel -s /bin/zsh <username>

passwd <username>

echo '<username> ALL=(ALL) ALL' > /etc/sudoers.d/<username>

Configure mkinitcpio with modules needed for the initrd image

vim /etc/mkinitcpio.conf

# Optional - for f2fs module crypto-crc32 is required however
MODULES=(crypto-crc32)

# Important - Use the correct order
HOOKS=(base systemd autodetect modconf block keyboard sd-vconsole sd-encrypt filesystems)

Regenerate initrd image

mkinitcpio -P

Setup systemd-boot

bootctl --path=/boot install

Enable Intel microcode updates

(For AMD replace intel-ucode with amd-ucode in every step that follows)

pacman -S intel-ucode

Create bootloader entry

Get luks-uuid with:

cryptsetup luksUUID /dev/nvme0n1p2

Create the entry:

vim /boot/loader/entries/arch.conf

title		Arch Linux
linux		/vmlinuz-linux
initrd		/intel-ucode.img
initrd		/initramfs-linux.img
options		rw luks.uuid=<uuid> luks.name=<uuid>=luks root=/dev/mapper/luks

Set default bootloader entry

vim /boot/loader/loader.conf

default		arch

(Optional) - Setup Gnome

pacman -S gnome

systemctl enable gdm

Exit, unmount and reboot

exit

umount -R /mnt

reboot
