I'm not yet running 12.04, but it is mostly like a driver issue.

Oky please post your /var/log/xorg.0.log , Let's debug what had failed.
I think it first tired to load the proprietary driver and failed.

I'm personally using nvidia graphic card in my laptop,but first time it got failed[not only xorg failed, whole kernel
got a pannic], then I configure it to load open source nvidia drivers instead of proprietary onces.

--Thank you--

Are you running Ubuntu in VirtualBox or you have installed it into the PC as a sole OS?

Not getting the required screen resolution is the issue.
This may be due to several root case(s). Probably due to one root case.

1. VGA card does not support that mode.
2. xserver does not configured properly.( automatic configuration)
3. your computer does not have the driver,for your video drive.
4. xserver does not configured to load the driver.
5. Your monitor does not support that screen resolution.

if the case is 3, you could go with open source drivers ( ex- nouveau ) or VESA driver and get the screen
resolution that you need, but you won't be able to get Graphics Hardware support upt to some extend.
Hardware T&L will be supported up to some extent with nouveau, but features beyond that won't be
supported.


The good part is you don't need to troubleshoot for cases 1-5. Your xserver will do that for you. Error
is already written in /var/log/Xorg.0.log . You could open that text file in vi(if it didn't come to
xserver correctly) and search for (EE) .

If you can't then post the file. I'll see what I could do for you.
