I had a similar problem (upon upgrade from feisty to gutsy) and I think it was a problem with gnome-power-manager. When I ran gnome-power-manager in a terminal, it couldn't find /usr/lib/libwnck-1.so-18.
I made a symbolic link as follows: sudo ln -s /usr/lib/libwnck-1.so.22 /usr/lib/libwnck-1.so.18 and made sure that gnome-power-manager was running in my gnome session, (System->Preferences->Sessions and check Power Manager) and now there is no hang. -- gnome-session hangs when "lo" is not correctly configured https://bugs.launchpad.net/bugs/26419 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
