I upgraded to 9.04 from 8.10 last night from the update manager. After the update/upgrade completed, I restarted the computer as instructed. When it came to the login screen my keyboard and mouse did not respond. I have tried restarting and using the recovery console to start dbus and hal to no success. I turn the numlock on to see when the keyboard shuts off and it is after Ubuntu is loaded but before the login screen appears. The computer is not frozen so some how 9.04 is disabling my mouse and keyboard. I am using a standard ps/2 keyboard and a 7 button usb mouse.
