By chance. I run root2user. I did not write the password and closed root2user by pprocess. After reboot I was still fido user. It was not possible to change to root by login manager.The only way I know for running as fido is to use the 'fido' button at first shutdown.
How did you "permanently change the user to fido user" ?
I tried to change the password (for fido user?) by root2user. This password did not work in login manager and when I started for example puppy package manager. In login manager only worked the password "woofwoof", but after the reboot I was still fido user.
It was not possible to run rxvt. I have no time to check on and finally I reinstalled racy:)
