This is Arch Linux with Full Disk Encryption (LVM on LUKS) for Dell XPS 15 7590

Based on:

[IMPORTANT] ASSUMPTIONS

I assume that /dev/nvme0n1 is the system's disk, and /dev/sda is USB drive.
RAM is 32G

STEPS

Download arch iso image from https://www.archlinux.org/ and copy to a USB drive.
```
# dd if=arch.iso of=/dev/sdb
```

Boot up and pressing the F2 key

 Under 'System Configuration', change the SATA Mode from the default "RAID" to "AHCI". This will allow Linux to detect the NVME SSD.
 Under 'Secure Boot', disable secure boot to allow Linux to boot.
 Under 'POST Behaviour', change "Fastboot" to "Thorough". This prevents intermittent boot failures.

 Save & Reboot

Connect to internet. Useful commands:

# iwctl --passphrase <passphrase> station wlan0 connect <SSID>

Partitioning

# gdisk /dev/nvme0n1

# o

# n
# 1
# 4096
# +512M
# ef00

# n 
# 2
# <Enter>
# <Enter>
# 8e00

# w
# y

Format Partitions:

# mkfs.fat -F32 /dev/nvme0n1p1

Setup encryption

# cryptsetup -c aes-xts-plain64 -y --use-random luksFormat /dev/nvme0n1p2
# cryptsetup luksOpen /dev/nvme0n1p2 luks

Create LVM Partitions This creates one partions for root, modify if /home or other partitions should be on separate partitions

# pvcreate /dev/mapper/luks
# vgcreate vg0 /dev/mapper/luks
# lvcreate --size 8G vg0 --name swap
# lvcreate -l +100%FREE vg0 --name root

Format LVM partitions

# mkfs.ext4 /dev/vg0/root
# mkswap /dev/vg0/swap

Mount the new system

# mount /dev/vg0/root /mnt
# mkdir /mnt/boot
# mount /dev/nvme0n1p1 /mnt/boot
# swapon /dev/vg0/swap

Install the base system

# pacstrap -i /mnt base base-devel linux linux-firmware lvm2 openssh git vim intel-ucode lm_sensors networkmanager

Generate /etc/fstab. This file can be used to define how disk partitions, various other block devices, or remote filesystems should be mounted into the filesystem.
```
# genfstab -pU /mnt >> /mnt/etc/fstab
```
(Optional) For making /tmp a ramdisk, add following line to /mnt/etc/fstab:
```
tmpfs	/tmp	tmpfs	defaults,noatime,mode=1777	0	0
```
Enter the new system
```
# arch-chroot /mnt /bin/bash
```

Set TimeZone

See available timezones:
# ls /usr/share/zoneinfo/

Set timezone:
# ln -s /usr/share/zoneinfo/Australia/Melbourne /etc/localtime

Set Locale

# vim /etc/locale.gen (uncomment en_US.UTF-8 UTF-8)
# locale-gen
# echo LANG=en_US.UTF-8 > /etc/locale.conf
  # export LANG=en_US.UTF-8

Set the hardware clock mode uniformly between your operating systems. Otherwise, they may overwrite the hardware clock and cause time shifts.
```
# hwclock --systohc --utc
```

Set hostname

# echo myhostname >/etc/hostname

Add it to /etc/hosts:

127.0.1.1	myhostname.localdomain	myhostname

Create User

# useradd -m -g users -G wheel chrislee
# passwd chrislee
# visudo
uncomment %wheel ALL=(ALL) ALL

Configure mkinitcpio with modules needed for the initrd image

# vim /etc/mkinitcpio.conf
MODULES=(ext4 nvidia nvidia_modeset nvidia_uvm nvidia_drm xhci_pci wd719x aic94xx)
HOOKS=(base systemd autodetect keyboard modconf block sd-encrypt sd-lvm2 filesystems fsck)
COMPRESSION="lz4"

Regenerate initrd image

# mkinitcpio -p linux

Setup systemd-boot

# bootctl --path=/boot install

# mkdir -p /boot/loader
# vim /boot/loader/loader.conf
default arch.conf
timeout 2
editor 0

# blkid -s UUID -o value /dev/nvme0n1p2

Copy UUID

# mkdir -p /boot/loader/entries/
# vim /boot/loader/entries/arch.conf

Enabled some services

# systemctl enable fstrim.timer
# systemctl enable NetworkManager

Exit new system and unmount all partitions
```
# exit
# umount -R /mnt
# swapoff -a
```
Reboot into the new system. Don't forget to remove the CD/USB.
```
# reboot
```
System is installed now. If you want to install Gnome desktop, perform following steps.
Setup WiFi
```
# nmtui
```
