My own notes installing Arch Linux with btrfs, disc encryption, auto-snapshots, no-noise fan-curves on my Asus ROG Zephyrus G14

[TOC]

Boot into BIOS and change your Harwareclock to UTC. Now booting Arch Linux, using a prepared Usbstick

Change keyboard layout with loadkeys de-latin1-nodeadkeys

For Network i use wireless, if you need wired please check the Arch WiKi.

Launch iwctl and connect to your AP station wlan0 connect YOURSSID Type exit to leave.

Update System clock with timedatectl set-ntp true

• My Disk is nvme0n1, check with lsblk

• Format Disk using gdisk /dev/nvme0n1 with this simple layout:

  • o for new partition table
  • n,1,<ENTER>,+1024M,ef00 for EFI Boot
  • n,2,<ENTER>,<ENTER>,8300 for the linux partition
  • w to save layout

Format the EFI Partition

mkfs.vfat -F 32 -n EFI /dev/nvme0n1p1

cryptsetup luksFormat /dev/nvme0n1p2
cryptsetup open /dev/nvme0n1p2 luks

mkfs.btrfs -f -L ROOTFS /dev/mapper/luks btrfs filesystem for root partition

Mount Partitions und create Subvol for btrfs. I dont want home, etc in my snapshots, so create subvol for them.

• mount -t btrfs LABEL=ROOTFS /mnt Mount root filesystem to /mnt
• btrfs sub create /mnt/@
• btrfs sub create /mnt/@home
• btrfs sub create /mnt/@snapshots
• btrfs sub create /mnt/@swap

truncate -s 0 /mnt/@swap/swapfile
chattr +C /mnt/@swap/swapfile
btrfs property set /mnt/@swap/swapfile compression none
fallocate -l 16G /mnt/@swap/swapfile
chmod 600 /mnt/@swap/swapfile
mkswap /mnt/@swap/swapfile
mkdir /mnt/@/swap

Just unmount with umount /mnt/ and remount with subvolumes

mount -o noatime,compress=zstd,commit=120,subvol=@ /dev/mapper/luks /mnt
mkdir -p /mnt/boot
mkdir -p /mnt/home
mkdir -p /mnt/.snapshots
mkdir -p /mnt/btrfs

mount -o noatime,compress=zstd,commit=120,subvol=@home /dev/mapper/luks /mnt/home/
mount -o noatime,compress=zstd,commit=120,subvol=@snapshots /dev/mapper/luks /mnt/.snapshots/
mount -o noatime,commit=120,subvol=@swap /dev/mapper/luks /mnt/swap/

mount /dev/nvme0n1p1 /mnt/boot/

mount -o noatime,compress=zstd,commit=120,subvolid=5 /dev/mapper/luks /mnt/btrfs/

Check mountmoints with df -Th

pacstrap /mnt base base-devel linux linux-firmware btrfs-progs nano vi networkmanager amd-ucode

After this, generate the filesystem table using genfstab -Lp /mnt >> /mnt/etc/fstab

Add swapfile echo "/swap/swapfile none swap defaults 0 0" >> /mnt/etc/fstab

arch-chroot /mnt
echo {MYHOSTNAME} > /etc/hostname
echo LANG=de_DE.UTF-8 > /etc/locale.conf
echo LANGUAGE=de_DE >> /etc/locale.conf
echo KEYMAP=de-latin1-nodeadkeys > /etc/vconsole.conf
echo FONT=lat9w-16 >> /etc/vconsole.conf
ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime

Modify nano /etc/hosts with these entries. For static IPs, remove 127.0.1.1

127.0.0.1		localhost
::1				localhost
127.0.1.1		{MYHOSTNAME}.localdomain	{MYHOSTNAME}

nano /etc/locale.gen to uncomment the following lines

de_DE.UTF-8 UTF-8
de_DE ISO-8859-1
de_DE@euro ISO-8859-15
en_US.UTF-8

Execute locale-gen to create the locales now

Add a password for root using passwd root

nano /etc/mkinitcpio.conf and add encrypt btrfs to hooks between block/filesystems

HOOKS="base udev autodetect modconf block encrypt btrfs filesystems keyboard fsck

Also include amdgpu in the MODULES section

create Initramfs using mkinitcpio -p linux

bootctl --path=/boot install installs bootloader

nano /boot/loader/loader.conf delete anything and add these few lines and save

default	arch.conf
timeout	3
editor	0

nano /boot/loader/entries/arch.conf with these lines and save.

title	Arch Linux
linux	/vmlinuz-linux
initrd	/amd-ucode.img
initrd	/initramfs-linux.img

copy boot-options with echo "options cryptdevice=UUID=$(blkid -s UUID -o value /dev/nvme0n1p2):luks root=/dev/mapper/luks rootflags=subvol=@ rw" >> /boot/loader/entries/arch.conf

using nano /etc/modprobe.d/blacklist-nvidia-nouveau.conf with these lines

	blacklist nouveau
	options nouveau modeset=0

Type exit to exit chroot

umount -R /mnt/ to unmount all volumes

Now its time to reboot into the new system!

Configure WiFi Connection.

systemctl enable --now NetworkManager
nmcli device wifi connect "{YOURSSID}" password "{SSIDPASSWORD}"

systemctl enable --now systemd-timesyncd.service

(You may look at /etc/systemd/timesyncd.conf for default values and change if necessary)

First create a new local user and point it to bash

useradd -m -g users -G wheel,lp,power,audio -s /bin/bash {MYUSERNAME}
passwd {MYUSERNAME}

Execute visudo and uncomment %wheel ALL=(ALL) ALL

Now exit and relogin with the new {MYUSERNAME}

Install some Deamons before we reboot

sudo pacman -Sy acpid dbus
sudo systemctl enable acpid

The goal is to have automatic snapshots each time i made changes with pacman. The hook creates a snapshot to ".snapshots\STABLE". So if something goes wrong i can boot from this snapshot and rollback my system.

First i create the snapshot and changes by hand to test if anythink is working. After that it will be done automaticly by our hook and script.

sudo -i
btrfs sub snap / /.snapshots/STABLE
cp /boot/vmlinuz-linux /boot/vmlinuz-linux-stable
cp /boot/amd-ucode.img /boot/amd-ucode-stable.img
cp /boot/initramfs-linux.img /boot/initramfs-linux-stable.img
cp /boot/loader/entries/arch.conf /boot/loader/entries/stable.conf

Edit /boot/loader/entries/stable.conf to boot from STABLE snapshot

title   Arch Linux Stable
linux   /vmlinuz-linux-stable
initrd  /amd-ucode-stable.img
initrd  /initramfs-linux-stable.img
options ... rootflags=subvol=@snapshots/STABLE rw

Now edit the /.snapshots/STABLE/etc/fstab to change the root to the new snapshot/STABLE

ˋˋˋ ... LABEL=ROOTFS / btrfs rw,noatime,.....subvol=@snapshots/STABLE ... ˋˋˋ

reboot and test if you can boot from the stable snapshot.

Copy the script from my Repo to

/usr/bin/autosnap and make it executable with chmod +x /usr/bin/autosnap

Copy the script from my Repo to

/etc/pacman.d/hooks/00-autosnap.hook

Now each time pacman executes, it launches the autosnapscript which takes a snapshot from the current system.

Install xorg and xfce4 packages

sudo pacman -Sy xorg xfce4 xfce4-goodies xf86-input-synaptics gvfs xdg-user-dirs ttf-dejavu pulseaudio network-manager-applet firefox-i18n-de git git-lfs curl wget

sudo localectl set-x11-keymap de pc105 deadgraveacute
xdg-user-dirs-update

LightDM Loginmanager

sudo pacman -S lightdm lightdm-gtk-greeter lightdm-gtk-greeter-settings
sudo systemctl enable lightdm

Reboot and login to your new Desktop. For Theming i followed this realy nice howto from Linux Scoop channel.

I like to use oh-my-zsh with Powerlevel10K theme

sudo pacman -Sy zsh zsh-completions
chsh -s /bin/zsh # (relogin to activate)
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
cd ~/.local/share/fonts
wget https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Regular.ttf
wget https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Bold.ttf
wget https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Italic.ttf
wget https://github.com/romkatv/powerlevel10k-media/raw/master/MesloLGS%20NF%20Bold%20Italic.ttf
fc-cache -v
git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

Set ZSH_THEME="powerlevel10k/powerlevel10k" in ~/.zshrc

Plymouth is in AUR , just clone the Repo and make the Package (i create a subfolder AUR within my homefolder)

cd AUR
git clone https://aur.archlinux.org/plymouth-git.git
makepkg -is

Now modify the Hooks for the Initramfs using /etc/mkinitcpio.conf, Plymouth must be right after "base udev". Delete encrypt hook, it will be replaced by plymouth-encrypt

HOOKS="base udev plymouth plymouth-encrypt autodetect modconf block btrfs filesystems keyboard fsck

Run mkinitcpio -p linux

Add some kernel-parameters to make boot smooth. Edit /boot/loader/entries/arch.conf and append to options

...rootflags=subvol=@ quiet splash loglevel=3 rd.systemd.show_status=auto rd.udev.log_priority=3 vt.global_cursor_default=0 rw

Optional: replace LightDM with the plymouth variant

sudo systemctl disable lightdm
sudo systemctl enable lightdm-plymouth

For Plymouth Theming and Options, check Plymouth on Arch Wiki

For XFCE4 Theming you could check this nice Youtube Video from Linux Scoop

I'am going to use the nvidia-dkms package, as i will use a custom kernel

sudo pacman -Sy nvidia-dkms nvidia-settings nvidia-prime acpi_call linux-headers

Reboot after install.

sudo bash -c "echo -e '\r[g14]\nSigLevel = DatabaseNever Optional TrustAll\nServer = https://arch.asus-linux.org\n' >> /etc/pacman.conf"

sudo pacman -Sy asusctl supergfxctl
sudo systemctl enable --now power-profiles-daemon.service
sudo systemctl enable --now supergfxd

sudo pacman -Sy linux-g14 linux-g14-headers
sudo sed -i 's/vmlinuz-linux/vmlinuz-linux-g14/' /boot/loader/entries/arch.conf
sudo sed -i 's/initramfs-linux/initramfs-linux-g14/' /boot/loader/entries/arch.conf

Reboot now!

After reboot you can check available features with asusctl -s . Fan curves, profiles should be possible with custom kernel.

You can use my file from etc/asusd/profiles.conf. But its better to delete the existing file, after reboot its regenerated with default and read-out values, The file is self -descriptive.

systemctl --user enable asus-notify
systemctl --user start asus-notify

For more fine-tuning read the asusctl Manual

Install required bluetooth modules and add your user to the group lp

sudo pacman -Sy bluez bluez-utils blueman
sudo systemctl enable --now bluethooth.service

Since iam running full disc encryption, i would like to enable autologin to my X-Session. Open /etc/lightdm/lightdm.conf and add theese under [Seat:*]

pam-service=lightdm
pam-autologin-service=lightdm-autologin
autologin-user={MYUSERNAME}
autologin-user-timeout=0
session-wrapper=/etc/lightdm/Xsession
greeter-session=lightdm-greeter

Now create the group autologin and add your user

sudo groupadd -r autologin
sudo gpasswd -a {MYUSERNAME} autologin
