Today I updated my ubuntu OS on my PC. However, since I am using the 845G video cards, then....

Hangs with desktop effects on Intel 830MG and 845G video cards

There is a bug in the Intel video driver for the older intel 830 and 845 integrated video cards that are used on laptops like the IBM R30. Desktop effects with compiz will not work on those chips and will freeze the system. For new installations, please install using the safe graphics mode (press F4 in the startup screen) on these systems and disable desktop effects via System -> Preferences -> Appearance, clicking on "Visual effects" and choosing "None".

however, the release note doesn't give the solution for system upgrading from old versions.

Now I find a solution: Login Window --> "Options" (lower left corner) --> "Select Session" --> "Fail safe Terminal" --> Login with your name and password --> type "gconf-editor" --> Desktop->Goname->Application->windows_manager --> Replace all "/usr/bin/compiz" with "/usr/bin/metacity" --> reboot --> "Options" (lower left corner) --> "Select Session" --> "GNOME" --> Login, that's ok!
