[SOLVED] SDDM doesn't let me log in manually

When I start the computer, I get automatically logged into my i3 session; I've been using it this year a lot, but I have also other DEs and WMs, like Plasma (both X11 and Wayland). I tried to logged in today and noticed that I can't. I think that the latest change I made since the last time I went through this process with success is adding gnome-keyrings, but I could be wrong. I leave all the information that I find relevant to know, but feel free to ask for anything else.

Here are the PAM files:

cat  /etc/pam.d/sddm
#%PAM-1.0

auth       include     system-login
#auth       optional    pam_gnome_keyring.so
#auth       optional    pam_kwallet5.so

account    include     system-login

password   include     system-login
#password   optional    pam_gnome_keyring.so    use_authtok

session    include     system-login
session    optional    pam_keyinit.so          force revoke
#session    optional    pam_gnome_keyring.so    auto_start
#session    optional    pam_kwallet5.so         auto_start

cat /etc/pam.d/sddm-autologin
#%PAM-1.0
auth        required    pam_env.so
auth        required    pam_faillock.so preauth
auth        required    pam_shells.so
auth        required    pam_nologin.so
auth        required    pam_permit.so
#auth       optional    pam_gnome_keyring.so
#auth       optional    pam_kwallet5.so
account     include     system-local-login
password    include     system-local-login
session     include     system-local-login
#session    optional    pam_gnome_keyring.so auto_start
#session    optional    pam_kwallet5.so auto_start

These are the files on /etc/sddm.conf.d (/etc/sddm.conf is empty)

cat /etc/sddm.conf.d/kde_settings.conf

Re: [SOLVED] SDDM doesn't let me log in manually

Don't "-r" and also no "-u", from your desscription and "Auth: sddm-helper exited with 255" I guess you cannot get an SDDM login screen?
What if you use any other theme than breeze (in doubt the built-in one)?

If that's not it, please post your complete system journal for a boot covering the failure:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

for the current one.

Re: [SOLVED] SDDM doesn't let me log in manually

I had a somewhat similar issue: The SDDM login screen appears, but nothing happens after entering the password. Your suggestion about the Breeze theme made me try switching themes (installed themes can be found under /usr/share/sddm/themes).

I switched to eucalyptus-drop. The change can be made in the file /etc/sddm.conf.d/kde_settings.conf (needs root privileges).

After that, I could login again. Hope this might help.

Edit: There is an open ticket about this issue here: https://gitlab.archlinux.org/archlinux/ … -/issues/5

Thank you both for replying! I was about to reply this:

Thanks for replying!
Since I log into i3 automatically, in order to get to SDDM I need to log out. I'm not sure if that's the explanation.

But then I read this comment and tried it

and YES!! It was it all along, for some reason the theme was the issue!
