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?

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

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.
