I got some new information about this bug. First of all it does happen on more than one of my computers, it's not an isolated problem, to be more precise, both computers have been upgraded from a 9.10 distro.
I was able to start a terminal windows during the problem of the toolbar not appearing and try different things. It happens that the real problem here isn't gnome-session as I initially tough but gnome-panel. Trying to kill gnome-session to restart it popped an error window indicating that the application gnome-panel does not answer, proving that this process hanged. So the next time I tried to kill gnome-panel and taa-daa, the bar eventually showed up after the process being automatically restarted. So the culprit here is gnome-panel. ** Also affects: gnome-panel Importance: Undecided Status: New -- gnome-session often doesn't start properly in 10.04 https://bugs.launchpad.net/bugs/576259 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
