This just happened to me during a routine update - gdm was updated and caused a complete GDM failure "Unable to authenticate" --- I had to go into a terminal screen "C-A-F1" and rollback the update using 'aptitude' - thank goodness that worked!!!
from version 2.28.1-0ubuntu1 to 2.28.1-0ubuntu2 I feel this is a CRITICAL error that would prevent many users from using (and rescuing) their desktop -- GDM fails to authenticate pre-existent users. https://bugs.launchpad.net/bugs/432492 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
