I have a very similar bug. This has appeared over a number of OS installations. Currently with 10.04. I'm running a Dell Inspiron 5400 and having issues with the screen going black, and remaining so. This happens most often when I've had the lid closed, but perhaps 10% of the time I'm just sitting watching my screen and *bango* black screen. Mouse movement doesn't bring it back. I have all powersaving options turned off. No hybernate, or screen blank, or screensaver. This can happen even just a few seconds after key/mouse interaction (though not often). I have not tried any of the suggested solutions, but just wanted to add that when this does happen to me, I've found that opening and shutting the lid... many times... eventually gets me to where the backlight comes on again. I can also sometimes see a very black impression of windows onscreen, so I know that the LCD is displaying stuff but the backlight isn't on. It's pretty obvious when I shut/open the lid when I've "got it"... when it's OK the screen is blank, but I can see the backlight is operational. I then just touch the mousepad to get the display back to normal. Every once in a while it takes dozens of close/open tests to get it to work, and once in a blue moon I just (hard reset) reboot and it's right straight away. Very annoying little bug. Next time I will try the suggested workarounds and report on progress.
