Same problem almost directly after loading the system 13.04. This time the Software Updater also stalled as shown in the screenshot, maybe because of the "ubuntu-bug" run? See also bug 1090414.
I could start the Software Updater using the Dash and it stalled at the grub-pc. After reboot and dpkg reconfigure everything was OK again. ** Attachment added: "Screenshot from 2012-12-14 11:26:36.png" https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/989588/+attachment/3459982/+files/Screenshot%20from%202012-12-14%2011%3A26%3A36.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/989588 Title: update-manager popup is shown on launcher and alt-tab list but window doesn't show up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/989588/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
