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
Pacman Entropy1. Open a terminal as root and run
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.
pacman-key --populate archlinux
You can automatically scan for updates to your aur installed packages with 'cower -vdu'
