Black Screen During Installation of Ubuntu help?

So here's the deal, i install ubuntu 11.10 alongside windows blah blah, well when i restart my computer and choose to run ubuntu, it says finishing installation.... or whatever and then the backlight to my laptop goes off, making it black of course, and then thats it. Remains that way forever! I've tried all the avaiable options of running ubuntu, like the graphics safe mode, verbose, all of that, does no good. I've also reinstalled several times from hard disc, virtual drive (mounting the .iso image), installing off usb, and simply running off usb. Also, i've tried both running and installing from an actually live disk of Ubuntu 10.04. I figure Ubuntu has a real problem with my graphics card, but surely there is a fix right? My specs follow..thanks for your help in advance!

It's not the brightness because the screen actually shuts off, you can tell that the backlight has turned off, but I went ahead and tried the method listed in answer #2 and it still didn't work. I did notice however that when it's listing what's happening before the monitor shuts off it kinda pauses on "ignoring bios query" then continues displaying the boot junk until the screen goes off shortly after. Of course it's going to fast to read too much.

Update 2:

And not that it really matters but I updated to windows ultimate

    Sounds like it may be a BIOS related issue or a Driver issue. I'm leaning towards a Driver, first.

    To save yourself a tone of trouble with drivers, try a Live DVD of "Ultimate Edition (UE)". It is Ubuntu but the author has pre-packed it with a ton of drivers, wireless support for laptops etc. Version 2.8 or 2.9 might work for you.

    Ubuntu 11.10 is does not have all the kinks worked out just yet so maybe give that UE a shot since your options are more open.

    I've seen a few HP machines with this, and it's was a BIOS bug. The default monitor brightness is set at 0 in one of the acpi tables. If the increase brightness hotkeys don't work try booting without acpi. (append "noacpi" to end of the kernel= line in grub. Either way should let you change the default in the settings/power menu.
