Elogind
elogind is a login manager and provides support for
- setting up necessary permissions for the desktop environment or window manager
- handling poweroff, reboot, suspend and hibernate via loginctl command
Installation
# apk add elogind polkit-elogind
- rc-update add elogind
- rc-service elogind start
Configuration
logind.conf
Edit /etc/elogind/logind.conf to configure handling of power events, such as suspending the computer when power button is pressed:
# sed -i 's|#HandlePowerKey=poweroff|HandlePowerKey=suspend|' /etc/elogind/logind.conf
Working with Desktop Environments
If using a Window Manager or Desktop Environment, such as Sway, the user must ensure that login session is correctly configured. When correctly configured, the loginctl command should output the following:
~$ loginctl SESSION UID USER SEAT TTY c1 105 sddm seat0 c2 1000 User seat0 tty8 2 sessions listed.
If the output is No session available., such as in the case of launching Sway from tty, suspend and many other functionality will not work. The user then must configure a display manager such as greetd, SDDM or lightdm.
PAM
To use the XDG enviroment variables from elogind PAM has to be set up.
