Can't login with any graphical display manager if I change my password

It was because I was using special chars in the password.

I normally use SDDM but I have also tried GDM, LightDM and LXDM.

I can log into VTTYs and use sudo with any password, but display managers only work with my current password (i.e. if I change it, DM login breaks, but if I change it back it works again).

When it fails the DM's log will say either "[PAM] Permission denied" or, for SDDM, "Authentication is already in progress". It doesn't matter whether the password is correct if I have changed it from the working value.

I've tried reinstalling PAM and display managers with no effect.

Any ideas what's wrong?

That's probably your keyboard layout, which is not set to the one you expect it to be, so when you try to write a special character, another one is actually written.
