I am trying to install 12.4 LTS on my wife's Dell All-in-One Inspiron One. I am using a previously-used CD image, so I know the CD is OK. Install process starts normally with the line-by-line output, but before the graphical output starts, the display goes dark and stays dark. Once the process reaches the point where a response is required to continue, it hangs there because there is no way to respond. If I play with the mouse, I can sometimes get a quick flicker of the graphic image, but the screen then goes dark immediately. I've installed every Ubuntu release since 8.4 on a number of different computers, but I have never experienced this problem! Have tried a number of searches on the forums, but haven't hit upon any key which gets close to this problem. Any and all help will be welcomed. If I can't overcome this, my wife will be yoked to Windows 7....forever?
Please help if you can. Thanks in advance.
