Hi Alexander, thanks for your quick reply. I have alltray installed but not used. Just to take care of your advise I uninstalled it sudo apt-get --purge alltray rm -r -f ~/.alltray
It made no difference. Still the same problem. Now I am at home and does not start. At work today afternoon wonderful. I hope we can find out somehow where the bug is. -- Thunderbird does not start when second display is missing https://bugs.launchpad.net/bugs/363983 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
