My Arch Linux Setup
This describes how to setup Arch Linux similar to my setup. This is rarely up-to-date, so be mindful when you type in your commands in the commandline, and be sure to check the Arch Linux Installation guide or the Arch Wiki in general, if you’re unsure about something.
Select the mirror(s) you want to use for the package manager
pacman. Delete every other entry or mark it as a comment to ensure that
pacman is using the right mirror.
You can also install vim (if not already installed on the live disc) with pacman by typing
pacman -Sy vim for more convenient text editing.
UEFI or BIOS?
To check if your system is using EFI, run the command:
If the directory exists and contains files then your system is using EFI. If that is not the case you are probably using BIOS and this cheatsheet will probably not work to install Arch Linux on your machine.
Attention: This process will wipe your entire harddrive!
Listing current drives and partitions
To check which drives are installed on the system and what partitions there are these commands might be helpful:
Partitioning your drives
If your system is using EFI use gdisk for better compatibility
Make sure to memorize the partition numbers and which partition is for what purpose.
To partition your drives (your standard harddrive should be /dev/sda), utilize the command
gdisk /dev/sdx where
x is the driver letter (e.g. “a”)
Clear the parition table
To clear the partition table type
o in gdisk
Command (? for help): o
Create a new partition
Create a new partition by typing
Command (? for help): n
You will be asked, what number your partition should have. This will be displayed as
x is the driver letter and
Y is the partition number.
After this you will be asked about the First Sector and the Last sector of the disk. For the First Sector you choose the default value.
For the Last Sector you can either specify a number (e.g. 4196) or how big the sector/partition should be. This is done by typing a
+ followed by the size of the sector. For
gdisk to know if you are using megabytes, gigabytes or something else, you need to specify this by a letter at the end of the line (e.g.
Megabytes or G for
gdisk now asks for the type of your partition. This is where you want to be specific.
If you do not have a EFI Partition (e.g. when you cleared your partition table) you have to create one. If your drive already has an EFI Partition then you can skip this step.
The EFI Partition should be 512 Megabytes big and has a hexcode of
You need at least one other partition for the filesystem to go.
- Create a new partition by typing
nin the prompt
- Select the size of your partition (depending on if you want to add a seperate

If you want to add a seperate
/home partition to your drive, do the same as with the
To create a
swap partition on your drive do the following:
- Create a new partition by typing
nin the prompt
- Select the size of your partition (a swap partition should be at least as big as your RAM, the recommended size is 2x of your RAM)
- The hexcode of swap is
At last write the changes to the disk with
Make sure to check the drive with
gdisk -l /dev/sdx!
Formatting the partitions
mkfs command allows you to format a partition to a desired filesystem.
The EFI Partition uses
vfat. To format it with
The linux filesystem uses
ext4, so your
\home partitions should be formatted with
To make your swap Partition one, use the
To enable your swap Partition, use the
swapon /dev/sdxY command.
To disable a swap Partition, use the
swapoff /dev/sdxY command.
Installing Arch Linux
To mount a partition, utilize the
mount /dev/sdxY /mount/point command.
To unmount a partition, utilize the
umount /dev/sdxY command.
For convenience we mount the partition where the root filesystem should go to
Make sure you select the right partition!
mount /dev/sdxY /mnt
If you have a seperate partition for your
/home directorys, create a directory in the already mounted root filesystem. This directory NEEDS to be called
After the directory is created, mount the partition where your
/home directorys should go to the newly created folder.
mount /dev/sdxY /mnt/home
The EFI Partition goes here.
First create a directory in the mounted root filesystem called
boot to mount the EFI Partition.
When the directory is created, mount the EFI Partition to the newly created folder.
mount /dev/sdxY /mnt/boot
To install the filesystem for Arch Linux, we use a tool called
pacstrap which is included in the live disc.
Assuming you mounted the partition where your root filesystem should go is
/mnt, do the following:
This will install all necessary files to that partition.
bootctl is part of the systemd suite.
bootctl we have to enter the newly installed Arch Linux system. This is done via
When you are in your Arch system, use the command
bootctl install to install
bootctl. It should detect everything it needs by itself.
When this is done, check your
/boot directory for the necessary files.
If these are present, move on to the next step.
Now you have configure the
loader.conf found in
Note: The Arch Linux installation you have entered does not contain vim as an editor. You have to manually download it using pacman -S vim.
loader.conf. For now you can copy this configuration file:
default arch timeout 4 editor 0
Next you need to configure
arch.conf located in
Again, for now copy this configuration file:
title Arch Linux linux /vmlinuz-linux initrd /intel-ucode.img initrd /initramfs-linux.img options root=PARTUUID="YOUR DRIVE UUID" rw
initrd line is optional but should be used when using an intel CPU. This will ensure your CPU will get updated before starting the kernel.
You can install the package by issuing the command
sudo pacman -S intel-ucode.
To figure out what PARTUUID your drive has, type in this command:
blkid -s PARTUUID -o value /dev/sdxY
Configuring Arch Linux
fstab allows your PC to mount partitions on boot.
Generate a fstab file (without arch-chroot into the system):
genfstab -U /mnt >> /mnt/etc/fstab
For fstab configuration, see fstab.
Set the time zone:
ln -sf /usr/share/zoneinfo/Region/City /etc/localtime
hwclock to generate
This command assumes the hardware clock to be set to UTC.
en_US.UTF-8 UTF-8 and other needed localizations in
/etc/locale.gen, and generate them with:
Set the LANG variable in
/etc/locale.conf accordingly, for example:
If you set the keyboard layout, make the changes persistent in
/etc/vconsole.conf (does not keep the keyboard layout for WM’s or DE’s):
Add matching entries to
127.0.0.1 localhost ::1 localhost 127.0.1.1 myhostname.localdomain myhostname
Here: netctl Alternatives: wpa_supplicant
Copy the example file from
/etc/netctl/mywirelessnetwork and edit the file accordingly.
Set the root password:
The system is now ready for boot.
Locking the root account:
passwd -l root
Unlocking the root account:
sudo passwd -u root
Add a new user:
useradd -m -g initial_group -G additional_groups -s login_shell username
For later convenience with
xbacklight we set the initial_group to
wheel and the additional_groups to
video. Shells used can be
To temporary grant root privileges to a user, use
pacman -S sudo
To configure sudo to allow the just added user to escalate privileges, we uncommented a line from
%wheel ALL=(ALL) ALL
To install Xorg:
sudo pacman -S xorg-server
To install the noveau drivers:
sudo pacman -S mesa
The noveau drivers should be loaded on default.
For Nvidia drivers, you first have to determine what graphics card you use by issuing the command
lspci -k | grep -A 2 -E "(VGA|3D)".
… follow the guide linked above

ALSA is already installed on Linux.
To install PulseAudio:
sudo pacman -S pulseaudio pulseaudio-alsa
To install bluetooth support and an equalizer, use
sudo pacman -S pulseaudio-bluetooth pulseaudio-equalizer respectively.
systemd-timesyncd is part of the systemd suite, which is installed by default.
To enable systemd-timesyncd:
timedatectl set-ntp true
To install DNSSEC and DNSCrypt:
sudo pacman -S ldns
yay -S dnscrypt-proxy-go
To install Ufw:
sudo pacman -S ufw

Solid State Drive
To install fonts, use
pacman or the AUR.
To refresh the font-cache:
To list all fonts:
By default, non-root users are not allowed to change the brightness of the screen.
To change this, we add the user to the video group and allow this group to modify the file for the brightness.
The file is located in
SUBSYSTEM=="backlight", ACTION=="add", RUN+="/bin/chgrp video %S%p/brightness", RUN+="/bin/chmod g+w %S%p/brightness"
Another option is using brightnessctl if xbacklight is not working.
If all else fails, there is still the option to manually change the brightness (or put it in a script/write a program) with, for example:
printf "<value>\n" > /sys/class/backlight/intel_backlight/brightness (path to brightness file might be different for you).
To install lxdm or LightDM:
sudo pacman -S lxdm
sudo pacman -S lightdm
To enable a display manager on boot:
sudo systemctl enable displaymanager.service
If you do not want to use a Display Manager, you can choose to execute
startx on login in a terminal.
First, make sure your
~/.xserverrc is properly configured:
#!/bin/sh exec /usr/bin/Xorg -nolisten tcp "$@" vt$XDG_VTNR
Second, if you are using bash add the following lines to your
~/.bash_profile or if you are using zsh add them to your
