Login problem

[manuel]

If nothing else helps, create a good backups of your personal data and reinstall. Might be the fastest way forward.

Well, create a good backup anyway!

My personal data is not a problem, but setting up the system again as I have it now (or better say: before it was messed) will take too long time, if at all possible.
I believe it is something easy to repair, but how? Why login doesn’t know my password?

I wanted to clean up my disks and used rmlint-shredder for it.

In general using packages like this and bleachbit can be dangerous if you do not know what you are doing.

[Barqu]

What packages could be broken and should be reinstalled?

pam
systemd
gdm

else?

Nope, password still said to be incorrect.

Possibly you have a different keyboard layout set up, so check the password is being typed as expected.

This is also possible:

Watch out: `pam` 1.4.0 may require manual intervention (pam_tally dropped)

pam has been updated and the tally and tally2 modules were dropped. If these modules are present in your /etc/pam.d/system-login then your login will fail despite a correct user/pass (both in DM and terminal). If you have altered the file contents in the past (e.g. you set up login via fingerprint reader) then pacman won’t replace it with the new version. If you don’t make the change before rebooting then entering single-user mode (or using a chroot) will get you into the system, where you can…

Locale is correct, but I have used fingerprint. Will read and try to understand your link, thanks.

Edit: Problem solved, thank you very much jonathon.
