    Arch Linux Arm Desktop Environment Tutorial:


Tutorial on how to setup a desktop environment on Arch Linux Arm, specifically for the Raspberry Pi 3*
Any questions on the steps can be left on a comment, or checking the Arch Wiki
Newer kernel versions are being tested, as well as Wayland instead of X
If you have questions or errors, leave a comment! - moral-g

Boot:


lsblk
fdisk /dev/sdX

X filing in for lsblk output

Type o. This will clear out any partitions on the drive.
Type p to list partitions. There should be no partitions left.
Type n, then p for primary, 1 for the first partition on the drive, press ENTER to accept the default first sector, then type +200M for the last sector.
Type t, then c to set the first partition to type W95 FAT32 (LBA).
Type n, then p for primary, 2 for the second partition on the drive, and then press ENTER twice to accept the default first and last sector.
Write the partition table and exit by typing w.


mkfs.vfat /dev/sdX1
mkdir boot
mount /dev/sdX1 boot
mkfs.ext4 /dev/sdX2
mkdir root
mount /dev/sdX2 root
wget http://os.archlinuxarm.org/os/ArchLinuxARM-rpi-armv7-latest.tar.gz
bsdtar -xpf ArchLinuxARM-rpi-armv7-latest.tar.gz -C root
sync
Move boot files to the first partition:
mv root/boot/* boot
sync
umount /dev/sdX*

Insert formatted SD card into the Raspberry Pi and power on
Login to root [pw:root] (alarm [pw:alarm] doesn't have [doas|sudo|etc] yet)

Locale, keymap, timezone:


Edit the /etc/console.conf and set the following line accordingly (if unsure: localectl list-keymaps)

KEYMAP=us

Edit the /etc/locale.conf and set the following line accordingly (if unsure: cat /etc/locale.gen | less)

LANG=en_US.UTF-8  

Edit the /etc/locale.gen and uncomment the one specified in /etc/locale.conf (above)
Finish with:

locale-gen

Run timedatectl set-timezone Zone/SubZone (if unsure: timedatectl list-timezones)

timedatectl set-timezone America/New_York
Pacman keyring initialization and population, as well as mirror:


pacman-key --init
pacman-key --populate archlinuxarm

Edit /etc/pacman.conf and uncomment or add the following lines:

SigLevel = Required DatabaseOptional
LocalFileSigLevel = Optional

Edit the /etc/pacman.d/mirrorlist and uncomment the wanted ones

Wi-Fi Setup (skip if using ethernet):


Wi-Fi setup
Option 1: [easier but must be redo every reboot]

wifi-menu

Option 2:
Edit the /etc/systemd/network/wlan0.network and add:

[Match]
Name=wlan0

[Network]
Description=On-board wireless NIC
DHCP=yes

Finish with:

systemctl restart systemd-networkd  

Edit the /etc/wpa_supplicant/wpa_supplicant-wlan0.conf and add:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
network={
     ssid="SSID"
     scan_ssid=1
     key_mgmt=WPA-PSK
     psk="PASSWORD"
}

Finish with:

systemctl start wpa_supplicant@wlan0.service
systemctl ENABLE wpa_supplicant@wlan0.service

IF WLAN0 DOES NOT SHOW:

rmmod brcmfmac && modprobe brcmfmac
reboot
Downloading [sudo|doas|etc] and other essentials:


Configure sudo, doas, or any root user pacakge for the users
Make sure you exit and login to alarm [pw:alarm]

EVERYTHING FROM NOW WILL BE DONE IN DEFAULT USER 'ALARM': make sure you [sudo|doas|etc]
Changing the config.txt:


Edit the /boot/config.txt and make sure it contains:

dtoverlay=vc4-kms-v3d
disable_overscan=1

FROM THIS POINT IT IS RECOMMENEDED TO SSH INTO THE PI: FIND THE IP BY ip addr show wlan0 or ip addr show eth0

X-Server:


Update pacman and packages:

pacman -Syu

Once all are downloaded and installed, one more package:

pacman -S accountsservice

Add the correct permissions:

usermod -aG video,tty,audio alarm

Edit /etc/X11/Xwrapper.config, it must have:

allowed_users=anybody
needs_root_rights=yes

X-server is now done

Desktop and Window Manager:


Download and configure your Desktop Environment and Window Manager
NO matter the DE or WM you must add:


Edit /etc/X11/xinit/xinitrc and add ):

xset s off
xset -dpms
xset s noblank

Copy system xinitrc to personal

cp /etc/X11/xinit/xinitrc ~/.xinitrc
Input troubles?:


Remove xf86-input-libinput and replace with xf86-input-evdev, DO NOT get rid of xorg if prompted:

sudo pacman -Rdd xf86-input-libinput
sudo pacman -Sw xf86-input-evdev
sudo pacman -U /var/cache/pacman/pkg/xf86-input-evdev-VERSION.pkg.tar.xz
Fin:


sudo reboot
