I got same isuue. Real problem is not the GDM, but changes in pam.d as any application, which required authentication, requested entering password twice.
Sollution is to add in /etc/pam.d/common-auth clausule 'try_first_pass': auth requisite pam_unix.so nullok_secure try_first_pass I'm not sure, which package messed it up. ** Changed in: gdm (Ubuntu) Status: Incomplete => Confirmed -- GDM asks for password twice during login https://bugs.launchpad.net/bugs/262910 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
