(Get the code!)
I have the same issue with Dell Studio 1747 (11.04 64bit).
Closing the lid enters suspend mode, but gives blank (no backlight) on return.
Hibernate shows the screen lock password prompt, then drops to a black screen with a blinking underscore which eventually freezes.
After cold-booting the system the fans spin extra-fast for some reason.
The problem persists invariantly of using fglrx or community-supported drivers for the video card (which is an ATI mobility radeon HD 560v). I thought that might be relevant because in 10.10 the problem would be present using community-supported drivers but not proprietary.
