[SOLVED] No session created after login in with sddm

Hi there,

I am logging in on tty3 over sddm to i3 on this override:

[Unit]
Description=Simple Desktop Display Manager
Documentation=man:sddm(1) man:sddm.conf(5)
Conflicts=getty@tty3.service

[Service]
Environment=DISPLAY=:1
Environment=XAUTHORITY=/root/.Xauthority
ExecStart=
ExecStart=-/usr/bin/sddm
#Restart=always

[Install]
Alias=autovt@tty3.service

No audio. When starting cmus it says "cmus: Error: an error occured while initializing MPRIS: No medium found. MPRIS will be disabled." "systemctl status --user" returns "Failed to connect to bus: $DBUS_SESSION_BUS_ADDRESS and $XDG_RUNTIME_DIR not defined"

printenv DBUS_SESSION_BUS_ADDRESS

returns nothing. No autologin used, i entered my password in sddm. No pacnew-files are in /etc/pam.d

/usr/lib/sddm/sddm.conf.d/default.conf

Any idea how to get sddm to crea a session and have the DBUS-environment-variables set?

[Edit]
I also can not switch my tty anymore after login into tty3
[/Edit]

[Edit2]
Maybe it is important that i copied shadow group passwd from my old system. This is a fresh installation.

Re: [SOLVED] No session created after login in with sddm

Normally I don't double post but I think a solution is worth it.

I just did
pacman -S dbus
and rebooted. Everything works again.

Re: [SOLVED] No session created after login in with sddm

dbus is dependency for systemd. Should be already in your system
