After trying to remove a normal user password (as I explain here) the pc just shows a black screen instead of the usual choose user to login with when starting the laptop.
Version of Ubuntu 19.10
Could it be it was related to the option of direct access without password left checked?
And how can I solved this?
Please, bear with me and read the other question, my answer and my updates, as I explain what I did to try to undo this mess (I had added this issue details in there because there was a 40 min limits before posting another question on askubuntu).
Sorry for my convoluted posts.
Atleast I can use that pc shared printer...
