Can't log in after changing SDDM Theme then reboot.

Hello people.

I have this issue with my laptop, I did change the SDDM theme then reboot it and try my pin that I always used to log in but it says failed to log in. I'm pretty sure that I used the right pin and tried to used other pins and password that I used but it doesn't work. right now it's stuck on the log in screen.  Is there another way to log in or I need to factory reset my arch.

Thanks.

Re: Can't log in after changing SDDM Theme then reboot.

Switch into tty (eg.: <CTRL>+<ALT>+<F4>) and LogIn via your USERNAME and PASSWORD at the textual prompt; once logged-in:

1. Post here output of

   # journalctl -b --no-pager

   or, if you'd like to try, do:

2. backup and remove SDDM configuration files (look for them by reading SDDM's relevant WIKI's page) then:

   $ sudo systemctl restart sddm.service

SDDM Themes are broken - after install you be left with a black screen.

you can boot to a terminal and :

cd /etc/
sudo nano sddm.conf

replace everything with :

[Autologin]
Relogin=false
Session=
User=

[General]
HaltCommand=/usr/bin/systemctl poweroff
Numlock=on
RebootCommand=/usr/bin/systemctl reboot

[Theme]
Current=breeze
CursorTheme=breeze_cursors
FacesDir=/usr/share/sddm/faces
ThemeDir=/usr/share/sddm/themes

[Users]
DefaultPath=/bin:/usr/bin:/usr/local/bin
HideShells=
HideUsers=
MaximumUid=60000
MinimumUid=1000
RememberLastSession=true
RememberLastUser=true

[WaylandDisplay]
SessionCommand=/usr/share/sddm/scripts/wayland-session
SessionDir=/usr/share/wayland-sessions

[XDisplay]
DisplayCommand=/usr/share/sddm/scripts/Xsetup
DisplayStopCommand=/usr/share/sddm/scripts/Xstop
MinimumVT=1
ServerArguments=-nolisten tcp
ServerPath=/usr/bin/X
SessionCommand=/usr/share/sddm/scripts/Xsession
SessionDir=/usr/share/xsessions
XauthPath=/usr/bin/xauth
XephyrPath=/usr/bin/Xephyr

Save the file and reboot.

You'll get the default sddm greeter.

If you can't boot to a shell, and you have a Windows system on another partition you can use this btfrs driver here :

https://github.com/maharmstone/btrfs

Get the latest release and install - Windows will recognize and mount the volume.

After that just do the above in any text editor and save.

Boot to Arch again.

If anyone has the default SDDM Greeter - Can you please paste it here ?

Hope this helps.
