[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

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

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

Having the same error again. This time reinstalling dbus does not help at all. Maybe this gives any more clues?

Er ... why did you do that? Did you save the originals from the new installation? Have you tried reverting them?

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

Solved by changing linux-lts to linux… whatever
