After an update (evidently kernel and headers, etc.) I was unable to logon as usual (graphic login screen). Neither the one configured user (Admin, with
sudo privileges) nor
root can log on in the normal fashion (graphic login) after the latest
apt upgrade. I rebooted, was presented with the login screen, and tried to login with both accounts. Passwords were not recognized for either of them.
This is the detail of the update:
2020-12-11 19:23:23 status installed linux-image-5.4.0-58-generic:amd64 5.4.0-58.64 2020-12-11 19:22:43 status installed linux-modules-extra-5.4.0-58-generic:amd64 5.4.0-58.64 2020-12-11 19:22:43 status installed linux-image-generic-hwe-20.04:amd64 184.108.40.206.61 2020-12-11 19:22:43 status installed linux-generic-hwe-20.04:amd64 220.127.116.11.61 2020-12-11 19:22:42 status installed linux-image-5.4.0-58-generic:amd64 5.4.0-58.64 2020-12-11 19:22:42 status installed linux-headers-generic-hwe-20.04:amd64 18.104.22.168.61 2020-12-11 19:22:41 status installed linux-headers-5.4.0-58-generic:amd64 5.4.0-58.64 2020-12-11 19:22:26 status installed linux-modules-5.4.0-58-generic:amd64 5.4.0-58.64 2020-12-11 19:22:26 status installed linux-headers-5.4.0-58:all 5.4.0-58.64
As stated-- after reboot I was unable to logon in the normal manner-- the default graphic logon would not recognize the password for either the one configured user (Admin, with
sudo privileges) or with
root. Switching to a text terminal both logins were accepted. I then created a new (Admin) user and a graphic logon succeeded for that account. Though it seems unrelated, auto-login was enabled for the configured user, but not for the new account.
How can I restore graphic logon for the existing user account and for root?
