First Steps

Add users to required groups: https://wiki.archlinux.org/index.php/users_and_groups#Group_list

Enable microcode updates: https://wiki.archlinux.org/index.php/microcode

Install systemd-boot pacman hook: https://wiki.archlinux.org/index.php/systemd-boot#Automatically

Enable SDDM: systemctl enable sddm

Configuration

Setup GPG SmartCard

echo "enable-ssh-support" >> ~/.gnupg/gpg-agent.conf
echo "pcsc-driver /usr/lib/libpcsclite.so" > ~/.gnupg/scdaemon.conf
echo "card-timeout 5" >> ~/.gnupg/scdaemon.conf
echo "disable-ccid" >> ~/.gnupg/scdaemon.conf
systemctl enable pcscd
systemctl start pcscd

Fetch your public key from the SmartCard:

gpg --card-edit
gpg/card> fetch

Adjust System Limits

Edit /etc/systemd/system.conf.d/limits.conf

[Manager]
DefaultLimitNOFILE=32768
DefaultTasksMax=32768

Suspend issues

Should you suffer from suspend issues (like the system resuming from sleep immediately), this is most likely caused by the USB chipset acting up. To prevent that, create a new systemd unit /etc/systemd/system/disable-usb-wakeup.service:

[Unit]
Description=Disable USB wakeup triggers in /proc/acpi/wakeup

[Service]
Type=oneshot
ExecStart=/bin/sh -c "echo XHC > /proc/acpi/wakeup"
ExecStop=/bin/sh -c "echo XHC > /proc/acpi/wakeup"
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

Enable & start the new unit now:

systemctl enable disable-usb-wakeup
systemctl start disable-usb-wakeup
