After restarting and relogging in, miraculously (without doing anything), the icon/right click menu came back. I also noticed that while I logged on to GNOME, the word Nautilus floated for several seconds.
But strange things keep coming up. Window borders were gone. I can't move them. Clicking `Show desktop' can't function, together with an error (see error1.png). Checking `Preference' --> `Windows', I got this message (error2.png). The window list can't list out working windows. I don't know what went wrong here. Perhaps it might have to do with my not closing all active windows before switching to another OS (Mac OS X) and downloading games which are not supported by Ubuntu and can't launch. Those games can't launch for me to play. So I don't know if the system kept running when I rebooted. I use Mac IBook G4 running PPC. I'm a novice to Ubuntu and Linux and wish to know more. By the way, is there some restoration programme for novice who might have got stuck somewhere in Ubuntu? ** Attachment added: "error1.png" http://librarian.launchpad.net/7400882/error1.png -- Ubuntu Feisty Desktop https://bugs.launchpad.net/bugs/109675 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
