Ubuntu Installation :: Black Screen After Login But Cursor Still Showing

when I boot and login to a fresh install of Ubuntu, everything goes fine, the login screen appears, I login. Then the cursor appears on a black screen. This is normal. Then when the desktop should appear, on the very left edge of the screen, about 5 pixels in size, you can see the panel and the rest of the desktop. But I stress, You still see the cursor. In this small area, you can right click as you, even click on the menu and it will come down, you can see it. I can click on Ubuntu SC and the cursor will turn to a loading symbol. But then nothing again. I can press Ctrl + Alt + F2 and terminal will come on fine. So far, this has happened on a live CD of Maverick, A live USB of Maverick, A Natty Narwhal Fresh Install, A Maverick Fresh install, A Karmic Old Install and That same Karmic After going through a Distro upgrade via Ctrl + Alt + F2 to 11.04. I've gotten all the updates for all of them (A slow, bandwidth wasting process), and this doen't happen on other computers, even ones with lower graphics cards then mine. Additionally, on the same computer on a seperate partion, I can load my main Maverick just fine, Indicateing that it can't be a hardware problem. After searching across the internet, I'm at loss to an answer.
