Login manager

A login manager is necessary for quickly entering a graphical enviroment. greetd and greetd-tuigreet make for a simple and secure login enviroment. Install them through:

# apk add greetd greetd-tuigreet
# rc-update add greetd default

greetd will not work right away because it doesn't know which "greeter" to launch. Configure it in /etc/greetd/config.toml:

[terminal]
vt = 7

[default_session]
command = "tuigreet --cmd 'dbus-run-session nixGL wayfire 2>&1 >/dev/null' -t --user-menu --power-shutdown 'doas /sbin/poweroff' --power-reboot 'doas /sbin/reboot'"

user = "greetd"

Now the login manager will automatically start a Wayfire session upon login.

To also enable power management on the login screen add the greetd user to the _power group:

# addgroup greetd _power
