Section 01: Step-by-step guide of installing Arch Linux on your hardware 🚀

Step 01: Downloading Arch Linux image

1. Go to Arch Linux downloads page https://archlinux.org/download/

2. Find HTTP Direct Downloads section and choose any download mirror. Select a mirror that is geographically closer to your location.

3. On the mirror page find archive named like archlinux-YYYY.MM.DD-x86_64.iso or archlinux-x86_64.iso or any other file with .iso suffix. Other files (like .txt, .tar.gz and even .iso.sig) are not needed for installation process.

Step 02: Preparing installation medium

1. Insert a USB-stick into your PC with at least 2Gb of space availavle on it.

2. Find corresponding block device for USB-stick in /dev folder. Usually it is /dev/sdb.

💡 IMPORTANT NOTE: you need block device without a number on the end. If you have for example /dev/sdb, /dev/sdb1 and /dev/sdb2 you need /dev/sdb !

3. Burn previously downloaded Arch Linux ISO-image on a USB-stick (in my case it is /dev/sdb):

$ sudo dd conv=fsync oflag=direct status=progress \
          if=./archlinux-YYYY.MM.DD-x86_64.iso of=/dev/sdb

Step 03: Boot into Arch Linux medium

1. Insert the installation medium into the computer on which you are installing Arch Linux.

2. Power on your PC and press boot menu key. For Lenovo ThinkPad X1 Carbon series laptop, this key is F12.

3. Boot from USB-stick and wait until boot process is finished.

💡 IMPORTANT NOTE: not every device can run a system from USB-stick out of the box. Many BIOS'es by default come with activated Secure boot option.You might need to deactivate it in your BIOS.

Step 04: Syncronize packages

1. [Optional] Connect to WiFi using iwctl and check connection is established:

$ iwctl
[iwd]# station wlan0 get-networks
[iwd]# station wlan0 connect <Name of WiFi access point>
[iwd]# exit
$ ping 1.1.1.1

2. Synchronize pacman packaes:

$ pacman -Syy

Step 05: Disk partitioning

1. Partition main storage device using fdisk utility. You can find storage device name using lsblk command.

$ fdisk /dev/nvme0n1
                [repeat this command until existing partitions are deleted]
Command (m for help): d
Command (m for help): d
Command (m for help): d

                [create partition 1: efi]
Command (m for help): n
Partition number (1-128, default 1): Enter ↵
First sector (..., default 2048): Enter ↵
Last sector ...: +256M

                [create partition 2: main]
Command (m for help): n
Partition number (2-128, default 2): Enter ↵
First sector (..., default ...): Enter ↵
Last sector ...: -32G // double size of your RAM

                [create partition 3: swap]
Command (m for help): n
Partition number (3-128, default 3): Enter ↵
First sector (..., default ...): Enter ↵
Last sector ...: Enter ↵

                [change partition types]
Command (m for help): t
Partition number (1-3, default 1): 1
Partion type or alias (type L to list all): uefi
Command (m for help): t
Partition number (1-3, default 2): 2
Partion type or alias (type L to list all): linux
Command (m for help): t
Partition number (1-3, default 3): 3
Partion type or alias (type L to list all): swap

                [write partitioning to disk]
Command (m for help): w

2. Create filesystems on created disk partitions:

$ mkfs.fat -F 32 /dev/nvme0n1p1 # on EFI System partition
$ mkfs -t ext4 /dev/nvme0n1p2   # on Linux filesystem partition
$ mkswap /dev/nvme0n1p3         # on Linux swap partition

3. Correctly mount all filesystems to the /mnt:

$ mount /dev/nvme0n1p2 /mnt
$ mkdir -p /mnt/boot/efi
$ mount /dev/nvme0n1p1 /mnt/boot/efi
$ swapon /dev/nvme0n1p3

4. Install essential packages into new filesystem and generate fstab:

$ pacstrap -i /mnt base linux linux-firmware sudo vim
$ genfstab -U -p /mnt > /mnt/etc/fstab

Step 06: Basic configuration of new system

1. Chroot into freshly created filesystem:

$ arch-chroot /mnt

2. Setup system locale and timezone, sync hardware clock with system clock:

$ vim /etc/locale.gen   # uncomment your locales, i.e. `en_US.UTF-8` or `en_GB.UTF-8`
$ locale-gen
$ echo "LANG=en_US.UTF-8" > /etc/locale.conf                # choose your locale
$ ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime   # choose your timezone
$ hwclock --systohc

3. Setup system hostname:

$ echo yourhostname > /etc/hostname
$ vim /etc/hosts
    127.0.0.1 localhost
    ::1       localhost
    127.0.1.1 yourhostname

4. Add new users and setup passwords:

$ useradd -m -G wheel,storage,power,audio,video -s /bin/bash yourusername
$ passwd root
$ passwd yourusername

5. Add wheel group to sudoers file to allow users to run sudo:

$ visudo
    [uncomment following line in file]
    %wheel ALL=(ALL) ALL

6. Install and configure GRUB:

$ pacman -S grub efibootmgr
$ grub-install /dev/nvme0n1
$ grub-mkconfig -o /boot/grub/grub.cfg

7. Setup networking stack:

$ pacman -S dhcpcd networkmanager resolvconf
$ systemctl enable dhcpcd
$ systemctl enable NetworkManager
$ systemctl enable systemd-resolved

8. Exit chroot, unmount all disks and reboot:

$ exit
$ umount /mnt/boot/efi
$ umount /mnt
$ reboot

Section 04: F.A.Q.s, bug fixes and other useful tips and playbooks for Arch Linux 🪲

Playbook 01: Fix XHCI hibernation error

In some Linux kernels there are some broken USB 3.0 device drivers, that sometimes wake up the system right after you launch hibernation process. If you see errors like this in your dmesg command output after an unsuccessful hibernation:

xhci_hcd 0000:00:14.0: PM: pci_pm_freeze(): hcd_pci_suspend+0x0/0x20 returns -16
xhci_hcd 0000:00:14.0: PM: dpm_run_callback(): pci_pm_freeze+0x0/0xc0 returns -16
xhci_hcd 0000:00:14.0: PM: failed to freeze async: error -16

To fix the issue put following lines in /usr/lib/systemd/system-sleep/xhci and make this file executable:

#!/bin/sh

run_pre_hook() {
    echo "Disable xhci module before suspend at $(date)..." >> /tmp/systemd_suspend_log
    grep XHC.\*enable /proc/acpi/wakeup && echo XHC > /proc/acpi/wakeup
}

run_post_hook() {
    echo "Enable xhci module after wakeup from $(date)" >> /tmp/systemd_suspend_log
    grep XHC.\*disable /proc/acpi/wakeup && echo XHC > /proc/acpi/wakeup
}

case $1 in
    pre) run_pre_hook ;;
    post) run_post_hook ;;
esac

Playbook 02: Fix GRUB screen resolution

This can help if you have very tiny grub font on your 4k monitor

1. Open /etc/default/grub with text editor and add following lines:

GRUB_TERMINAL_OUTPUT="gfxterm"
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_GFXMODE=1920x1080x32,1024x768x32,auto

2. Generate grub.cfg:

$ sudo grub-mkconfig -o /boot/grub/grub.cfg

Playbook 03: Fix Lightdm screen resolution

This can help if you use lightdm and have very tiny font on your 4k monitor

Open /etc/lightdm/lightdm.conf file and add following line under [Seat:\*] section:

display-setup-script=xrandr --output eDP-1 --mode 1920x1080

P.S. your screen output name, like eDP-1 in my case, can be found in xrandr -q

Playbook 04: Activate dark mode in GTK apps

$ gsettings set org.gnome.desktop.interface color-scheme 'prefer-dark'

Playbook 05: System goes to sleep too fast with Xfce

• If system goes to sleep after 3-5 minutes, this might be screensaver. To stop this, disable option Settings -> Screensaver -> Activate Screensaver when computer is idle.

Playbook 06: All requests, expept those to internal addresses, fail after launching Wireguard VPN

• This happens when your Wireguard server can only handle requests only to configured IP addresses and DNS names. Use resolvectl revert wg0 (change wg0 to your wireguard interface name). This will prevent system from using Wireguard interface for all routes.

Playbook 07: Screen freezed (or hangs) after 2-10 minutes of inactivity when using Picom

• If you screen freezes (or hangs) while not touching keyboard or mouse for some time (usually 2-10 minutes), this might be an issue with picom. Try first stopping picom at all to see if this helps. If yes, try to change rendering backend of picom from xrender to glx and check if it helps. Worked for me.

Playbook 08: Remove annoying menubar from Slack

• Window -> Always show menu bar -> disable

Playbook 09: Encrypt external disk

1. [Only once] Select disk partition to be encrypted (in this example /dev/sdb1) and initialize LUKS:

$ sudo cryptsetup luksFormat /dev/sdb1

2. Open and decrypt LUKS partition, this will create decrypted device at /dev/mapper/cryptdev:

$ sudo cryptsetup open /dev/sdb1 cryptdev

3. [Only once] Initialize filesystem on decrypted partition, in this example ext4:

$ sudo mkfs.ext4 /dev/mapper/cryptdev

4. Mount created filesystem, to /mnt folder in this example, and use it as you want:

$ sudo mount /dev/mapper/cryptdev /mnt

5. Unmount filesystem and close LUKS device after using it:

$ sudo umount /mnt
$ sudo cryptsetup close cryptdev

6. [If needed] Change LUKS disk encryption passphrase:

TLDR: LUKS generates a single master key (also known as the "encryption key"), which is used to encrypt the data on the disk. Instead of storing the master key directly, LUKS uses key slots. Each slot contains the master key encrypted with a unique password or other authentication information. To change the password, we need to obtain LUKS slot number for the current key.

$ sudo cryptsetup luksDump /dev/sdb1             # most probably it will be 0
$ sudo cryptsetup luksChangeKey /dev/sdb1 -S 0   # use your own slot number in -S parameter
