Archlinux - My Sanctum Sanctorum

This guide is the only guide you'll ever need (lol) to set up your Archlinux system from ground up. Follow this only when you have gained familiarity to the Linux ecosystem using Ubuntu or any other OS. Preferable don't skip directly from Windows to Arch. You might wanna give Manjaro a try if you're coming from Windows, and are really keen on doing things the Arch way, since it's based on Arch, however has a GUI to help you out with most of the stuff. Well if you have time to kill and the internet at your disposal then you may begin your journey into the wonderful and awesome world of Arch Linux!

Requirements:

  • Internet
  • An old/new PC or laptop (I use Arch as my daily driver)
  • Patience
  • Patience
  • Patience

Make sure you have at least a few hours of spare time.

Create a bootable USB for Archlinux

On a Linux machine, connect the USB, and figure out the name of your USB using

lsblk

Run the following command, replacing {x} with your drive, e.g. /dev/sdb, if {x} = b. (Do not append a partition number, so do not use something like /dev/sdb1)

dd bs=4M if={path_to_archlinux.iso} of=/dev/sd{x} status=progress oflag=sync

Installation

  • Boot into BIOS and disable Secure Boot. UEFI is ON but Secure Boot is disabled. If you're not able to access the Secure Boot settings, set a Supervisor Password in BIOS and then try again.

  • If you have a wired internet connection, plug-in the ethernet cable before booting the PC.

  • Verify the Boot mode and ensure its UEFI. Do this by executing the command below and verifying the directory exists

    ls /sys/firmware/efi/efivars
    
  • Check the internet connection. Remember internet connection is mandatory.

    ping -c3 google.com
    
  • If connected, skip to the next step. Check the output of ip link command. It should show a list of network interfaces to connect to. The interfaces starting with 'w' are usually the ones dealing with WiFi, and those starting with 'e' deal with the ethernet connection.

    ip link
    

    If you have a wired ethernet cable, follow these steps, else, skip to the WiFi section. Connect your LAN cable and execute this

    systemctl start [email protected]{ethernet_interface_name}.service
    

    Try pinging again. You should be connected to the internet now.

Connection to WiFi:

  • Find/Confirm your WiFi interface

    iw dev
    
  • Activate it using the {wifi~interfacename~}

    ip link set {wifi_interface_name} up
    
  • Check if there's 'UP' in between '\<' and '>'. {wifi~interfacename~} will be referred to as {interface} henceforth

    ip link
    
  • Scan for WiFi

    iw dev {interface} scan | less
    

    If you're using it in adhoc mode (a mode in which there is no central controller), you'll have to mention it, using this command. If you're trying to connect to a WiFi router, it's NOT adhoc mode, and you DON'T need to execute this command, since the WiFi router acts as a central controller.

    ip link set {interface} down
    iw dev {interface} set type ibss
    ip link set {interface} up
    
    • Make a note of your

      • SSID (name of your network)
      • Security
    • Encryption

      • If there is no encryption on your WiFi, use

        iw dev {interface} connect "{your_ESSID}"
        
      • If there is encryption of type WEP

        • using a hexadecimal or ASCII key (the format is distinguished automatically, because a WEP key has a fixed length):

          iw dev {interface} connect "{your_ESSID}" key 0:{your_key}
          
        • using a hexadecimal or ASCII key, specifying the third set up key as default (keys are counted from zero, four are possible):

          iw dev interface connect "{your_ESSID}" key d:2:{your_key}
          
      • If it's WPA or WPA2

        • A passphrase is generated using

          wpa_passphrase {your_SSID} {passphrase}
          
        • Connect to the network using

          wpa_supplicant -B -i {interface} -c <(wpa_passphrase {MYSSID} {passphrase})
          
        • Get an IP address allocated to your PC using dhcp

          dhcpcd {interface}
          
  • Check if the interface is connected to the WiFi using

    iw dev {interface} link
    
  • Check the amount of bytes transmitted and received using

    iw dev {interface} station dump
    

    For more details visit this page

  • You can also SSH into this system if you want to execute commands remotely for ease of use:

    systemctl start sshd
    

    Now find the IP of this system using

    ip addr
    

    And to connect to this system remotely, execute this on the PC you want to connect to it form

    ssh {ip_addredd} -l root
    
  • Set date

    timedatectl set-ntp true
    
  • Partitioning the disk

    • Check the contents of the disk

      lsblk
      
    • Make sure none of the partitions you want to make are mounted by checking the MOUNTPOINT using

      lsblk -f
      

      In case they are mounted, use

      umount /dev/sd{device_letter}{partition_number}
      

      Do this for all the mounted partitions

    • Making partitions

      gdisk /dev/sd{device_letter}
      
      • Delete everything and create a new partition table

        o
        
      • Create a new EFI partition

        n
        
        • Partition number (1-128, default 1):

          # press RETURN for default
          
        • First Sector (34-976773134, default=2048) or {+-}size{KMGPT}:

          # press RETURN for default
          
        • Last Sector (2048-976773134, default=976773134) or {+-}size{KMGPT}:

          +512M
          
        • Current type is 'Linux filesystem' HEX code or GUID (L to show codes, Enter = 8300):

          EF00
          

          This makes it an EFI partition

      • Create a new SWAP partition

        n
        
        • Partition number (2-128, default 2):

          # press RETURN for default
          
        • First Sector (34-976773134, default=1050624) or {+-}size{KMGPT}:

          # press RETURN for default
          
        • Last Sector (1050624-976773134, default=976773134) or {+-}size{KMGPT}:

          +20G
          
        • Current type is 'Linux filesystem' HEX code or GUID (L to show codes, Enter = 8300):

          8200
          

          This makes it a SWAP partition

      • Create a new root partition

        n
        
        • Partition number (3-128, default 3):

          # press RETURN for default
          
        • First Sector (34-976773134, default=42993664) or {+-}size{KMGPT}:

          # press RETURN for default
          
        • Last Sector (42993664-976773134, default=976773134) or {+-}size{KMGPT}:

          +80G
          
        • Current type is 'Linux filesystem' HEX code or GUID (L to show codes, Enter = 8300):

          8304
          

          This makes it a root partition

      • Create a new home partition

        n
        
        • Partition number (3-128, default 3):

          # press RETURN for default
          
        • First Sector (34-976773134, default=210765824) or {+-}size{KMGPT}:

          # press RETURN for default
          
        • Last Sector (210765824-976773134, default=976773134) or {+-}size{KMGPT}:

          # press RETURN for default, to select the remainder of the disk
          
        • Current type is 'Linux filesystem' HEX code or GUID (L to show codes, Enter = 8300):

          8300
          

          This makes it a home partition

      Now write these changes to the disk

      w
      

      And proceed with a yes (Y) Now check if the partitions were made according to your liking

      lsblk
      
    • Formatting partitions

      mkfs.fat -F32 /dev/sda1  # format EFI partition as FAT32
      
      mkswap /dev/sda2         # format SWAP partition as SWAP
      swapon /dev/sda2
      
      mkfs.ext4 /dev/sda3      # format root partition as EXT4
      
      mkfs.ext4 /dev/sda4      # format home partition as EXT4
      
  • Mounting the file system. Same procedure to be followed for debugging Archlinux

    mount /dev/sda3 /mnt      # mount root
    
    mkdir -p /mnt/boot        # create boot directory in mount
    mount /dev/sda1 /mnt/boot # mount boot directory
    
    mkdir -p /mnt/home        # create boot directory in mount
    mount /dev/sda4 /mnt/home # mount boot directory
    
  • Install Archlinux

    pacstrap /mnt base base-devel
    
  • Generate an fstab file. The fstab file can be used to define how disk partitions, various other block devices, or remote filesystems should be mounted into the filesystem.

    genfstab -U /mnt >> /mnt/etc/fstab
    

    Check the resulting file in /mnt/etc/fstab afterwards, and edit it in case of errors.

  • Change root into the new system. Chroot is an operation that changes the apparent root directory for the current running process and their children. Changing root is commonly done for performing system maintenance on systems where booting and/or logging in is no longer possible.

    arch-chroot /mnt
    
  • Set the timezone

    ln -sf /usr/share/zoneinfo/{Region}/{City} /etc/localtime # Asia/Kolkata
    
  • Run hwclock to generate /etc/adjtime:

    hwclock --systohc
    
  • Uncomment en_US.UTF-8 UTF-8 and other needed localizations in /etc/locale.gen, and generate them with

    locale-gen
    
  • Set the LANG variable in /etc/locale.conf accordingly, for example:

    LANG=en_US.UTF-8
    LC_CTYPE=en_US.UTF-8
    LC_MESSAGES=en_US.UTF-8
    LC_ALL=en_US.UTF-8
    LANGUAGE="en_US.UTF-8"
    
  • Change the keyboard layout, by the /etc/vconsole.conf file. It is US English by default

    KEYMAP=us
    
  • Create hostname by editing /etc/hostname

    {my_host_name}
    
  • Add this to /etc/hosts, if it doesn't exist

    127.0.0.1 localhost.localdomain localhost
    ::1   localhost.localdomain localhost
    127.0.1.1 {my_host_name}.localdomain  {my_host_name}
    
  • Creating a new initramfs is usually not required, because mkinitcpio was run on installation of the linux package with pacstrap. But run it anyways

    mkinitcpio -p linux
    
  • Set the root password using

    passwd
    
  • Install intel-ucode. It provides microcode updates for Intel CPUs

    pacman -S intel-ucode
    
  • To use SystemD as the bootloader follow these steps. Alternatively you may use GRUB, skip this section to use GRUB

    • Installing the bootloader systemd-boot

      bootctl install
      bootctl update
      
    • Edit the /boot/loader/loader.conf file and remove the long text and replace it with

      default arch
      
    • Adding boot entries. Create a file /boot/loader/entries/arch.conf

      blkid -s UUID -o value /dev/sd{device_letter}{root_partition_number} > /boot/loader/entries/arch.conf
      

      The UUID of the root partition will be extracted and added to the arch.conf file.

    • Now edit the arch.conf file and add the following.

      title  Arch Linux
      linux  /vmlinuz-linux # it is vmlinuz not vmlinux
      initrd  /intel-ucode.img # intel ucode thing provided you have installed it already
      initrd  /initramfs-linux.img
      options root=UUID={UUID_of_root_partition} rw #  rw at the end is important
      
    • For hibernation, increase the size of sys/power/image~size~, if you have a large SWAP partition, and decrease if you have a small one. By default it is 2/5 th the RAM size. Then make an entry in arch.conf

      blkid -s UUID -o value /dev/sd{device_letter}{swap_partition_number} >> /boot/loader/entries/arch.conf
      

      This'll put the UUID of the SWAP partition at the end of the arch.conf file. Now modify the last line of the conf file

      options root=UUID={UUID_of_root_partition} resume=UUID={UUID_of_swap_partition} rw
      
  • Install packages to ease installation after boot List of packages needed

    • iproute2: for ip to manage networking
    • acpi: for checking battery percentage and stuff
    • iw: for wireless connections
    • wpa~supplicant~: for wireless WPA protected connections
    • git: a version control system
    • dialog: A tool to display dialog boxes from shell scripts
    • vim: a text editor
    • zsh: shell
    • curl: fetch things from internet
    • wget: fetch things from internet
    • aria2: the best download manager
    • xdg-user-dirs: auto create and link \$HOME directory folders like Documents, Downloads etc
    pacman -S iproute2 acpi iw wpa_supplicant dialog vim zsh git curl wget aria2 stow networkmanager xdg-user-dirs
    
  • Reboot PC after unmounting the mounted partition

    exit
    umount -R /mnt
    poweroff
    
  • Remove the installation media and start PC, and connect to internet

  • Optionally add your keys and turn on SSH for remote access

    mkdir -p ~/.ssh
    curl -L https://github.com/{username}.keys >> ~/.ssh/authorized_keys
    systemctl restart sshd
    

    You may SSH into the system now

  • Check battery

    acpi -b
    
  • Activating zsh and using antigen

    chsh -s $(which zsh)
    curl -L git.io/antigen > $HOME/antigen.zsh
    curl -L 'https://raw.githubusercontent.com/codingCoffee/effective-enigma/master/.zshrc' > $HOME/.zshrc
    exec zsh
    
  • Editing the /etc/pacman.conf for the better.

    1. Uncomment and/or add this.

      #UseSyslog
      #UseDelta #just mentioning, not fully supported in arch
      Color
      TotalDownload
      CheckSpace
      VerbosePkgLists
      ILoveCandy
      
    2. Skipping this step won't cause any harm Use aria2c as the download manager instead of wget. Add the following new entry just below the \"#XferCommand = /usr/bin/curl -C - -f %u > %o\" line. The 2 caveats are you won't be able to see the overall download size, but downloads will be faster, and everytime you do pacman -Syu the database files will be downloaded again.

      XferCommand = /usr/bin/aria2c --allow-overwrite=true --continue=true --file-allocation=none --log-level=error --max-tries=2 --max-connection-per-server=5 --max-file-not-found=1 --min-split-size=1M --no-conf --remote-time=true --summary-interval=0 --timeout=3 --dir=/ --out %o %u
      
  • Create a user

    useradd -m -G wheel {your_username}
    

    Assign password to user

    passwd {your_username}
    

    Give the user sudo access by un-commenting %wheel ALL=(ALL) ALL

    visudo
    

    su into your user

    su - {your_username}
    
  • Create the default folders using the xdg-user-dirs-update service

    xdg-user-dirs-update

DANGER!!!
Mere mortals, this is where you stop
DO NOT PROCEED FURTHER IF YOU DON'T KNOW WHAT YOU'RE DOING. IT CAN MESS UP YOUR SYSTEM REAL BAD

Learn a little about the system and then maybe come back here after a year to lean more.

YOU HAVE AN AMAZING SYSTEM UP AND RUNNING !!!
YOU HAVE BEEN WARNED!
  • NVIDIA Drivers for GTX 1060

    1. Installing nvidia optimus so that both GPUs can be used. Intel GPU is used for normal display, and Nvidia GPU can be used at will for machine learning and other stuff
