    Arch Linux installation and setup trouble shootings

Network Configuartion

Here are the summary of how to connect to the network (wireless/ethernet)
during the installation.
Wireless

This link
provides good explanation on how to connect to a WPA/WPA2 Wi-Fi network.

Setup the wireless device

# ip link set wlan0 up

FYI, you can find the interface name of your wireless device using
iw dev command.

Scan available Wi-Fi networks

# iw wlan0 scan | less

From the above command, you will get #ssid of the Wi-Fi network that
you'd like to connect.

Connect to wpa/wpa2 Wi-Fi network

# wpa_passphrase $ssid >> /etc/wpa_supplicant.conf
(type the passphrase)
# cat /etc/wpa_supplicant.conf
# reading passphrase from stdin
network={
    ssid=$ssid
    #psk=********
    psk=********
}
# wpa_supplicant -B -D nl80211 -i wlan0 -c /etc/wpa_supplicant.conf


Get IP adress by DHCP

# dhclient wlan0
# ping archlinux.org

Ethernet static address

WARNING: This section is mostly stale

NOTE: As of March, 2021, it is possible to configure static network using
only ip (i.e., ip address, ip set and ip route.

Add /etc/netctl/ethernet

Interface=$(interface name)
Connection=ethernet
IP=static
Address=('$(address)')
Gateway='$(gateway)'
DNS=('$(nameserver)')


Enable and start netctl

# netctl enable ethernet
# netctl start ethernet

Note that the latter command will fail, if the interface is already up.
In that case, use ip link set $interface down to turn off the interface
and then repeat it.
For sanity check, open /etc/resolv.conf to see whether the nameserver is
properly set. Otherwise, add nameserver $(nameserver address) to the file.

Connect and route
I am not 100% sure what's happening here, but let me just show how I was
able to connect to the network and route to proper gate.

# ifconfig $interface $address/24 up
# route add default gw $gateway
# ping archlinux.org

If everything was done correctly, you should be able to connect to the internet
at this point.
After installation, I prefer to install NetworkManager and use nmtui for
easy network configuration.
System partition

# mkfs.ext4 /dev/sdXY
# mount /dev/sdXY /mnt
# mkswap /dev/sdXZ
# swpaon /dev/sdXZ
# # Create EFI system partition
# mkfs.fat -F32 /dev/sdXW
# mount /dev/sdXW /mnt/efi
# genfstab -U /mnt >> /mnt/etc/fstab

Pacstraip and arch-chroot

Use pacatrap to install packages and arch-chroot to switch to Arch Linux root file system.
More information can be found in Arch Wiki.
Bootloader

Grub

Make sure the EFI partition is mounted at /boot/efi.
# pacman -S grub efibootmgr
# grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB --recheck
# grub-mkconfig -o /boot/grub/grub.cfg

For me, I mount EFI partition to /boot/efi, and it worked.
Nonetheless, I am not sure whether this is idiomatic, and I think this could be improved.

Language and input configuration

Locale


Generate locale with locale-gen
Uncomment your preferred locales from /etc/locale.gen and run locale-gen
to add locales.


Set locale


# localectl set-locale LANG=es_US.utf8


Run ibus-daemon to enable typing Korean on URvxt

# ibus-daemon -dxr
# cat .Xdefaults


Enable tap-to-click and natural scrolling with touchpad

# pacman -S libinput

TBD
Timezone

# timedatectl set-timezone Zone/City

TODO: How to sync with timeserver using different tools (e.g., ntpclient)
NVIDIA

# pacman -S nvidia
# nvidia-xconfig

Vulkan

# pacman -S vulkan-icd-loader nvidia-utils
# vulkaninfo

OpenCL/CUDA

# pacman -S ocl-icd clinfo opencl-nvidia cuda
# clinfo

Xorg

Setup minimal i3-wm environment

# pacman -S xorg-xserver xorg-xinit
# cat .xinitrc
setxbmap gb
exec i3

Bluetooth

# pacman -S bluez bluez-utils
# systemctl start bluetooth.service
# bluetooth ctl power on

To automatically enable bluetooth on system boot:
/etc/bluetooth/main.conf
