My computer boots to a black screen, what options do I have to fix it?

I have an nvidia geforce 295 GTX, and it works great in Windows.

However, when booting into Ubuntu I had intermittent problems for a while where the system theme went haywire, it looked like "windows classic" with gray windows et cetera. Then they stopped being intermittent, and I always had these boring gray windows. I tried finding a workaround uninstalling the nvidia drivers and downloading newer ones from Nvidias site.

I uninstalled them but couldn't shut down the xserver to command line. If I did /etc/init.d/gdm stop the system just hanged. I tried booting into recovery mode, but after a whole bunch of startup output my screen goes to sleep (eg no output).

Lastly this has escalated so now I don't get any image when I boot into a normal Ubuntu session

You don't say if you are using the latest nvidia Drivers, which would be useful in order to give you an answer. But assuming that you have the latest nVidia Drivers installed, try setting up your nVidia Settings by dropping the next in a terminal:

sudo nvidia-settings

After entering your password the nVidia X Server Settings window will appear, and after adjusting the parameters that make your screen look as you wish, click on the "X Server Display Configuration" in the left pane, then just save your changes by clicking the "Save to X Configuration File" button.

After that, a soft reboot of the X will be enough but if you reboot your machine will also do the trick. In order to soft-restart the X, press the [Ctrl][Alt][F1] in order to go to the console (text only) mode and drop the next command:

killall5

Please make sure you save all your open documents prior to do this because of the system is going to close down your session without allowing you to save anything.

Log in again and see the changes. If your configuration remains, it's time for a hardware reboot. Do it and check.

IMPORTANT NOTE: either that you can drop the single nvidia-settings command in the terminal, it won't allow you to save the changes. Do it as suggested and let's see what happen.

Just a question: which window's decoration manager are you using? your problem sounds more like a problem with Emerald or something. Sorry if my answer isn't what you expected.
