Simple-ArchLinux-Install-Guide

ArchLinux Installation From Scratch UEFI,GUI,Steam,VLC,Libre Office,OBS-STUDIO,flatpak it's a process,but the results are worth it.You will get a fully customizable system where you can make everything work exactly how you want it,sky is the limit!

0. Downloading the installation image and creating a bootable device using rufus or gnome-multi-writer utility:

• Download image here via torrent or direct link:https://www.archlinux.org/download/
• Use Rufus http://rufus.ie/ and select GPT and ISO mode for the image
• Also Balena Etcher portable is a nice tool https://www.balena.io/etcher/
• On Linux use gnome-multi-writer utility or ventoy

By default all current Arch installation mediums have a guided installer(better to use manual installation):

• archinstall

Alternative

• python -m archinstall guided

Formatting the SSD/HDD properly before installing Arch Linux or any other Linux distribution or operating system:

• sudo cfdisk /dev/sda
• sudo cfdisk /dev/nvme0n1
• Delete everything you see then Write>>Yes

Wipping the partition schemes

• sudo wipefs -a /dev/sda
• sudo wipefs /dev/nvme0n1

Deleting everything properly so no forencisc recovery is possible

• sudo shred -f -v /dev/sda
• sudo shred -f -v /nvme0n1

Also this works but it does not show the process:

• sudo shred /dev/sda
• sudo shred /dev/nvme0n1

NB!! when you are running into weird pgp errors during pacstrap,don't forget to run this command from the Arch ISO!:

• pacman -Sy archlinux-keyring

1.Creating partitions using cfdisk(easiest):

Run this command and delete everything,from free space create the following:

• cfdisk
• /dev/sdx1 512M Fat32(EFI)

NB!The size of the EFI must be 512MB and type should be EFI

(Optional) Swap patition size can be around 3-10GB

• /dev/sdx2 8-10GB swap

Main partition,remaining size can be as large as you want it to be:

• /dev/sdx3 200GB ext 4

2.Formatting the drives:

For the /dev/sdx1 use the following command:

• mkfs.fat -F32 /dev/sdx1

(Optional) For the swap /dev/sdx2 use the following commands:

• mkswap /dev/sdX2
• swapon /dev/sdX2

For the primary partition use the following command:

• mkfs.ext4 /dev/sdX3

3.Mounting the drives:

• mount /dev/sdX3 /mnt

4 Checking if everything worked:

• lsblk
• ip link

5.Installing basic packages and important stuff with wifi you will need the iw wpa_supplicant dialog packages:

For Non-LTS kernel(rolling) with Wi-Fi

• pacstrap /mnt base base-devel linux linux-headers linux-firmware nano vim networkmanager iw wpa_supplicant dialog

Non-LTS kernel(rolling) without Wi-Fi

• pacstrap /mnt base base-devel linux linux-headers linux-firmware nano vim networkmanager

(Optional)

For LTS kernel (Long Term Support) with Wi-Fi

• pacstrap /mnt base base-devel linux-lts linux-lts-headers linux-firmware nano vim networkmanager iw wpa_supplicant dialog

LTS Without Wifi

• pacstrap /mnt base base-devel linux-lts linux-lts-headers linux-firmware nano vim networkmanager

(Optional)

For both Non-LTS and LTS(have both options) with

• pacstrap /mnt base base-devel linux linux-headers linux-lts linux-lts-headers linux-firmware nano vim dhcpcd networkmanager iw wpa_supplicant dialog

Or if you hate networkmanager,but still need Wi-Fi:

• pacstrap /mnt base base-devel linux linux-headers linux-lts linux-lts-headers linux-firmware nano vim dhcpcd iwd iw wpa_supplicant dialog netctl

6. Generating fstab file:

• genfstab -U /mnt >> /mnt/etc/fstab

7.Switching to root.All the below commands must be used as root!

• arch-chroot /mnt /bin/bash

8.Setting locales:

A proper way to do it is to find this lines en_US.UTF-8 in locale.gen file and uncomment them:

• nano /etc/locale.gen
• locale-gen

9.Adding a main user:

• useradd -g users -G power,storage,wheel -m test

10.Assigning passwords for root and main user

Password for root:

• passwd

Password for main user:

• passwd your_new_user

11.Editing the sudoers file:

• visudo

Or

• nano /etc/sudoers

Ctrl+O to save,Ctrl+ X to exit after chages with nano.

Uncomment the settings in sudo file and add the main user to sudo(your username):

Lines to uncomment:

• sudo=ALL=(ALL:ALL) ALL

(Optional) Add yourself to the sudoers file under root(not recommended):

• username=ALL=(ALL:ALL) ALL

(Optional) Add yourself to sudoers file under sudo (safer option):

• sudo=ALL=(ALL:ALL) ALL
• username=ALL=(ALL:ALL) ALL

More secure way by uncommenting the following lines,without touching anything else:

• Defaults targetpw
• ALL ALL=(ALL:ALL)

Save changes to the sudoers file:

• :w! + Enter to exit and write changes
• :q + Enter exit

edit sudoers file with nano anytime:

• sudo nano /etc/sudoers

12.Grub and efi tools installation(very important step!):

Fuse 2 support (older option)

• pacman -S grub efibootmgr dosfstools os-prober mtools fuse2

Fuse 3 support (newer option)

• pacman -S grub efibootmgr dosfstools os-prober mtools fuse3

13. Creating efi boot directory on the EFI partition:

• mkdir /boot/efi

14. Mounting the FAT32 EFI partition:

• mount /dev/sdx1 /boot/efi

15. Grub installation and configuration(very important,otherwise system will not boot!):

• grub-install --target=x86_64-efi --bootloader-id=grub --efi-directory=/boot/efi

• grub-mkconfig -o /boot/grub/grub.cfg

16.Additional measures so that the boot does not become unbootable:

• mkdir /boot/efi/EFI/BOOT
• cp /boot/efi/EFI/GRUB/grubx64.efi /boot/efi/EFI/BOOT/BOOTX64.EFI

17.Exiting chroot and reboot:

• exit

Unmounting the live partitions and rebooting:

• umount -R /mnt
• reboot

18.The easy way to activate the wired connection using network manager.

• sudo systemctl enable NetworkManager.service
• sudo systemctl enable wpa_supplicant.service
• sudo systemctl start NetworkManager.service
• sudo reboot
• sudo nmtui

Select the desired wired connection it should be activated by default if not activate it

• ping archlinux.org

19.For Wi-Fi(Optional):

NB! Don't enable dhcpcd.service with Network Manager!

• sudo systemctl enable NetworkManager.service

Run these commands

• sudo usermod -a -G libvirt $(whoami)
• sudo systemctl restart libvirtd.service

(Optional)For GPU passthrough enable IOMMU in GRUB or Systemd-boot:

• For systemd-boot edit /boot/loader/loader.conf and add intel_iommu=on OR amd_iommu=on, and iommu=pt.

For AMD CPUs

• options root=/dev/sda2 amd_iommu=on iommu=pt

---

For Intel CPUs

• options root=/dev/sda2 intel_iommu=on iommu=pt

grub

• For grub edit /etc/default/grub and append your kernel options, intel_iommu=on OR amd_iommu=on and iommu=pt, to the GRUB_CMDLINE_LINUX_DEFAULT.

For AMD CPUs

• GRUB_CMDLINE_LINUX_DEFAULT="amd_iommu=on iommu=pt"

---

For Intel CPUs

• GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on iommu=pt"

And then automatically re-generate the grub.cfg file with:

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

Check if IOMMU is working

• dmesg | grep -e DMAR -e IOMMU

Check NVIDIA version:

• nvidia-smi -q | grep "VBIOS Version"

Download VBIOS and check other more complex tutorials on further steps,this is not recommended,it can cause issues,not all VBIOSES are supported,etc.

• https://www.techpowerup.com/vgabios/

NB if having trouble with GNOME Disks Utility or any other utility recognizing the NTFS file format

• sudo pacman -S ntfs-3g

Install and use the donwgrade tool from AUR:

• yay -S downgrade package name

Fix outdated yay or paru issues fast instead of reinstalling them:

• sudo ln -s /usr/lib/libalpm.so.14.0.0 /usr/lib/libalpm.so.13

NVIDIA Shadowplay with GPU screen recorder on Arch Linux

Get nvidia-patch: https://github.com/keylase/nvidia-patch

• Extract and go to the folder
• Open in terminal
• sudo ./patch-fbc.sh

Make sure you have yay or paru installed for AUR:

• yay -S gpu-screen-recorder-git

• yay -S gpu-screen-recorder-gtk

NB! Optional (not recommended) disabling kernel and driver updates for more stable experience

• sudo nano /etc/pacman.conf

Uncomment

• #IgnorePkg =
• #IgnoreGroup =

It should look like this for kernel and driver and for example firefox:

• IgnorePkg = linux nvidia firefox
• IgnoreGroup = linux nvidia firefox

For kernel only:

• IgnorePkg = linux
• IgnoreGroup = linux

View drivers in use

• lspci -v
• sudo lspci -v

(Optional) mkinitcpio:

• sudo mkinitcpio

That's it you are good for using pure ArchLinux and don't forget to view archwiki for more advanced commands and packages:

https://wiki.archlinux.org/

Don't forget to install and use man

• sudo pacman -S man
• man (your command here)

Example: man pacman

If you start getting errors like "signature from "John Smith john.smith@archlinux.org" is marginal trust" do these steps:

• sudo pacman -S archlinux-keyring
• sudo pacman -Syu archlinux-keyring
• sudo pacman -Syyuu

Run this in case it still occurs:

• sudo pacman-key --refresh-keys
• sudo pacman -Syu archlinux-keyring

(Optional) Adding a secondary SSD/HDD in fstab manually:

If it is an existing SSD/HDD that you already formatted with ext4 or btrfs and automounted in filemanager like Dolphin or Nemo,then you have to check in properties for example "/media/user/Backup" that is your mount point.

• sudo lsblk -f

• sudo nano /etc/fstab

Contents of FSTAB:
