Session manager

To use a graphical enviroment it is necessary to start a seat and session manager. For a minimal install it is recommended to use seatd, turnstile and polkit. To install those run:

# xbps-install -Sy seatd turnstile polkit

Then to enable them:

# ln -s /etc/sv/seatd /var/service
# ln -s /etc/sv/turnstiled /var/service

To be able to use seatd it is necessary that the user is added to the _seatd group.

# usermod -aG _seatd <user>

For turnstile to function configure /etc/pam.d/system-login by adding the line:

session optional pam_turnstile.so

Make sure turnstile also creates a Runtime Directory by enabling it in /etc/turnstile/turnstiled.conf.
