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
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.
- 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`
- Recursively remove the package without saving any backups and also remove unneeded dependencies `pacman -Rnsu noto-fonts`
- Recursively removing orphans and their configuration files:
- pacman -Rns $(pacman -Qtdq)
- If no orphans were found pacman outputs error: no targets specified. This is expected as no arguments were passed to pacman -Rns.
- Note: The arguments -Qt list only true orphans. To include packages which are optionally required by another package, pass the -t flag twice (i.e., -Qtt).

Pacman Entropy1. Open a terminal as root and run

pacman-key --populate archlinux
- You can automatically scan for updates to your aur installed packages with 'yay -a -Syu'
- Dealing with a Perl update
- When Perl gets updated you have to run this command for the previous perl version to get a list of all of the old modules: pacman -Qqo '/usr/lib/perl5/5.30'
- Then rebuild all of those modules: yay -a -S $Results_List
