Unity Launchpad error in Ubuntu 12.04 LTS (Precise Pangolin) Beta 1

In the last couple days, I encountered the Unity Launchpad error in Ubuntu 12.04 LTS (Precise Pangolin) Beta 1. I got the error dialog box displayed, closed it, got a blank screen, nothing there. No launchpad. How I got into the terminal or launched the application? How I fixed it? Launched the keyboard shortcut by pressed these keys together <Ctrl><Alt>T Now in the terminal, I ran these commands: ~$ sudo apt-get update ~$ sudo apt-get upgrade I thought the new updates would fix it. Still no launchpad. I typed this command at the terminal ~$ unity The launchpad launched. Still some glitches. Reboot. Repeated these processes above couple times, it worked.
