+# Artix Linux - Install and System Config

+**Attribution:**
+Most or much of this was generated by or derived from Grok, or else from Artix docs, Arch docs/wiki, or else the docs for the particular programs or packages used. I'm not claiming any of this is mine, just putting it here in one file for future convenience/reference.
+
+I used this approach in December of 2025 to install Artix Linux on a Framework 13in laptop from 2023 q4.
+
+- OS and distro: Artix Linux
+- init system: dinit
+- partitioning, GUID Partition Table:
+    - unencrypted boot partition (size: 512M), UEFI
+    - LUKS-encrypted LVM:
+        - swap partition (size: amount of memory + 4G)
+        - root/default partition (size: remaining space)
+
+For reference, doc page from Artix for installation:

+
+## install steps
+
+- [ ] if not already done, download artix ISO (dinit version) and dd it onto a usb drive
+
+- [ ] boot the live usb and select the install option (whatever it may look like)
+
+- [ ] connect to the internet
+
+```bash
+connmanctl
+//// within connmanctl
+enable wifi
+scan wifi
+agent on
+services
+connect <wifi_XXXXXXXXXXXXXXXX_managed_psk>
+quit
+```
+
+- [ ] verify connection using `ping`
+
+- [ ] update live system keys/mirrors
+
+```bash
+pacman -Sy artix-keyring
+```
+
+- [ ] run lsblk and identify the storage drive on which to install
+    - note: when i ran this in 2025 dec on my framework laptop, it was `/dev/nvme0n1`
+
+- [ ] partition the drive
+
+```bash
+cfdisk <target storage drive>
+# use GPT (guid partition table)
+# new partition, size 512M, type 'EFI System'
+# new partition, size (remaining), type 'Linux LVM'
+# write changes
+# quit cfdisk
+```
+
+- [ ] set up LVM volumes
+
+```bash
+cryptsetup luksFormat --type luks2 /dev/<LVM partition>
+cryptsetup open /dev/<LVM partition> artixlvm
+
+pvcreate /dev/mapper/artixlvm
+vgcreate artixvg /dev/mapper/artixlvm
+
+lvcreate -L <size of memory + 4G, e.g. 36G> artixvg -n swap
+lvcreate -l 100%FREE artixvg -n root
+```
+
+- [ ] set filesystems for partitions/volumes
+
+```bash
+mkfs.vfat -F32 /dev/<boot partition>
+mkfs.ext4 /dev/artixvg/root
+mkswap /dev/artixvg/swap
+```
+
+- [ ] mount the partitions/volumes
+
+```bash
+mount /dev/artixvg/root /mnt
+mkdir /mnt/boot
+mount /dev/<boot partition> /mnt/boot
+swapon /dev/artixvg/swap
+```
+
+- [ ] install base system and needed packages
+
+```bash
+basestrap /mnt base base-devel linux \
+    linux-firmware \
+    dinit elogind-dinit \
+    lvm2 cryptsetup grub efibootmgr mkinitcpio \
+    connman connman-dinit wpa_supplicant \
+    git less neovim zsh
+```
+
+- [ ] generate fstab
+```bash
+fstabgen -U /mnt >> /mnt/etc/fstab
+
+# verify (add noatime to ext4 line if desired)
+vi /mnt/etc/fstab
+```
+
+- [ ] chroot into installed system
+```bash
+artix-chroot /mnt
+```
+
+- [ ] set timezone, hardware clock, locale
+
+```bash
+ln -sf /usr/share/zoneinfo/<path to target zone> /etc/localtime
+hwclock --systohc
+
+nvim /etc/locale.gen
+# uncomment en_US.UTF-8 UTF-8; add others if desired
+
+locale-gen
+echo "LANG=en_US.UTF-8" > /etc/locale.conf
+```
+
+- [ ] set hostname and /etc/hosts
+
+```bash
+echo "<computer name>" > /etc/hostname
+
+nvim /etc/hosts
+# ensure /etc/hosts includes the following:
+127.0.0.1  localhost
+::1        localhost
+127.0.1.1  <computer name>.localdomain <computer name>"
+```
+
+- [ ] mkinitcpio with hooks
+
+```bash
+nvim /etc/mkinitcpio.conf
+# go to HOOKS and set it thus:
+HOOKS=(base udev autodetect keyboard keymap consolefont modconf block encrypt lvm2 resume filesystems fsck)
+
+mkinitcpio -P
+```
+
+- [ ] grub config and install
+
+```bash
+blkid
+# note the UUID of the LVM/LUKS partition
+
+nvim /etc/default/grub
+# ensure the following is set:
+GRUB_CMDLINE_LINUX="cryptdevice=UUID=<UUID from blkid above>:artixlvm root=/dev/mapper/artixvg-root resume=/dev/mapper/artixvg-swap quiet rw"
+
+grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=Artix
+grub-mkconfig -o /boot/grub/grub.cfg
+```
+
+- [ ] set up connman for installed system
+
+```bash
+mkdir -p /etc/dinit.d/boot.d
+ln -s ../connmand /etc/dinit.d/boot.d/connmand
+```
+
+- [ ] set root password, set up user
+
+```bash
+passwd
+
+useradd -m -G wheel,audio,video,optical,storage <username>
+passwd <username>
+pacman -S sudo
+EDITOR=nvim visudo
+# uncomment the line in /etc/sudoers which looks something like the below:
+echo "%wheel ALL=(ALL) ALL"
+```
+
+- [ ] close stuff out and reboot
+
+```bash
+exit
+umount -R /mnt
+swapoff -a
+cryptsetup close cryptlvm # may not work, just ignore and reboot
+reboot
+```
+
+---
+
+## system config (post install)
+
+_NOTE: don't put anything here which should be in my dotfiles-and-setup scripts instead_
+
+- [ ] set up chrony (for syncing system time with ntp servers)
+    - _NOTE: edit defaults in `/etc/chrony/chrony.conf` if desired_
+
+```bash
+sudo pacman -S chrony chrony-dinit
+
+# Fallback if dinitctl enable fails (symlink method)
+sudo mkdir -p /etc/dinit.d/boot.d
+sudo ln -s ../chronyd /etc/dinit.d/boot.d/chronyd
+# alt: sudo dinitctl enable chronyd
+
+/etc/dinit.d/chronyd start
+# alt: sudo dinitctl start chronyd
+```
+
+---
+
+## troubleshooting
+
+if i need to try something again and reopen the LVM, the below should work:
+
+```bash
+cryptsetup open /dev/<target device> artixlvm
+# enter existing password
+
+vgchange -ay artixvg
+# or, if only one VG exists:
+vgchange -ay
+```
+
+if date/time get messed up (such as due to battery running out), fix with:
+
+```bash
+# can manually adjust to local time; grok said "date is UTC if hardware is set that way"
+sudo date -s "2025-12-17 12:47:00"
+# or, if chrony, ntp, or similar is set up, can trigger sync
+chronyd -q
+# can check after with `date` or `chronyc tracking`
+
+sudo hwclock -w --utc
+```
