when I signed "switch user" and then login, black screen will happen, and then I must reboot the computer

[Danyding]

I have a problem with Ubuntu10.04, when I signed "switch user" and then login, black screen will happen, and then I must reboot the computer. And I have test that sometimes when I first signed "switch user", it works well, but if I button three consecutive hits, it will be black screen.
