Quirks

Now that dbus is no longer compiled with X11 support (Q4 2018) you have to call X11 apps like this:

sudo dbus-launch --exit-with-session nemo

Time

NTPd has been supplanted by Chrony and should not be used to serve time to clients.
If all that is required is a basic time client systemd's timesyncd should be used as it is the most lightweight.

systemd-timesyncd

  • The default NTP settings are compiled in by the vendor and can be overriden via /etc/systemd/timesyncd.conf
  • The most common commands are `timedatectl show-timesync` and `timedatectl set-ntp`

chrony

Packaging

  • Recursively remove the package without saving any backups and also remove unneeded dependencies `pacman -Rnsu noto-fonts`

Updating Mirrors

reflector -c US --fastest 5 --age 48 --protocol http --sort rate --verbose --save /etc/pacman.d/mirrorlist

Pacman Entropy

1. Open a terminal as root and run
pacman-key --init
2. Open a second terminal as root and run
cat /dev/sda > /dev/null
  • After about 1 minute the kernel will have enough "true" entropy to finish the command.
3. Finally run
pacman-key --populate archlinux

AUR

You can automatically scan for updates to your aur installed packages with 'cower -vdu'
