I can’t seam to login into my pc the login screen keeps reseting and not leting me in.
It maybe is Pams foult with the new update, but i can’t tell because journalctl is confusing to me.
Welcome to the forum! 
It is quite possible that you’ve been bitten by that.
Try booting up from the USB key or optical disk that you used for installing. Then, open up a terminal and issue the following command… 
su -
Enter the password, and then issue the following command…
manjaro-chroot -a
Then you can look for any .pacnew files under /etc/pam.d/, and tend to them as needed.
When you’re done, just enter…
exit
systemctl reboot
there isn’t .pacnew file or any hiden .files in /etc/pam.d/
What about the obvious then, i.e. …
- Mistyped the password?
- Caps Lock and/or Num Lock?
- Different keyboard layout/model?
when put in a wrong password it tells me its wrong, but when its right the screen goes black for a second then the mouse apears and then its right back at the login screen.
I looked at the journalctl and its giving me errors from sddm, sddm-greeter and sddm-helper
saying
Qoblject: Cannot create childern for a parent that is in difreant thread
and other stuff like virtualkeybord plugin is not isntalt ext.
Could this have samthing to do as to why i cant load in to my system.
That is possible. Are you using apparmor by any chance?
i have never used it. When i type aa-status it says:
apparmor module is loaded.
apparmor filesystem is not mounted.
I can’t check if ts running beacause chroot ignores the “systemctl status apparmor” command
Alright i tryied “systemctl status apparmor" again in the comand line at boot, heres what i got:
Loaded: loaded (/usr/lib/systemd/system/apparmor.service;enabled; vendor preset: disavled)
Active: Inactive (dead)
and aa-status has all zeros in frotn of profiles and processes
If I just copy paste all journalctl errors and ohter things i think might be relevent in here, would that be helpfull figuring out my problem?
I honestlly don’t know what else to do at this point.

It might at least shed a bit of light on the situation.

I went looking for pacnew files and i think they might be somthing importat
/etc/shadow.pacnew
/etc/fonts/fonts.conf.pacnew
/etc/security/limits.d/10-gcr.conf.pacnew
Delete /etc/shadow.pacnew - if you overwrite your existing /etc/shadow all your accounts passwords and related information will be lost.

Nop that didn’t fix it, still getting black screen when trying to log in
I probably should have mentioned that i used time shift to se if the bug was still there.
It is.
shadow.service: Failed with result 'exit-code'
That suggests that there’s a problem with logind, and thus with systemd.
I don’t know whether it’ll make a difference, but it could be related to systemd-homed, which is new, and which I’ve masked on my system.
sudo systemctl disable --now systemd-homed.service
sudo systemctl mask systemd-homed.service
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
Created symlink /etc/systemd/system/systemd-homed.service -> /dev/null.
this is what i got
