I checked anantshri's solution and it solved the issue for me (thanks anantshri =) I used the following console commands for package downgrade:
sudo aptitude install libpam-gnome-keyring=2.92.92.is.2.30.0-0ubuntu3 sudo aptitude install gnome-keyring=2.92.92.is.2.30.0-0ubuntu3 My fingerprint sensor is also working (it also did with 2.92.92.is.2.30.1-0ubuntu2 before, but i had to deactivate it, because the "missing panel" issue only occured when I included "auth sufficient pam_fprint.so" in "/etc/pam.d/common-auth"). -- gnome panels suddenly have a 25 second delay after session load https://bugs.launchpad.net/bugs/593226 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
