Ii. Summary

This problem was also encountered in the previous kernel version. It was also a Linux bug. At that time, it was very hard to understand what Dash went away, the Panel disappeared, and the title bar disappeared ...... I have come to the conclusion that unity has many bugs, and you should try to minimize the special effects! If you encounter these problems, you do not have to reinstall the system. Just be patient! We hope 12.04 will be more stable!
