Ubuntu 10.04 Resume from Hibernate

Resuming from hibernation in Ubuntu 10.04 shows a blank screen, then a corrupted video image for a second or two before showing the log in screen.
Changing the video resolution with Startup-Manager from 640×480 and 8 bits to 1024×768 and 24 bits replaced the blank screen with the Ubuntu Plymouth graphic and the message “resuming from “. There’s still the brief corrupted video before the log in screen, but at least there’s not a blank screen for half a minute. BTW, that corrupted video image has been there since Ubuntu 8. The video is an Intel 945GM Chipset.
