I have been looking for a solution in the various threads, but nothing's specific to the Dell Inspiron 1100.
I am able to boot the laptop using the install disc, and operation seems normal. Video works fine and access to the hardware is no problem. When I install Ubuntu, replacing any other OS, I can run through all the steps all the way to the end getting the message to reboot. Once I reboot, the display shows the purple-ish center screen for a moment, without the Ubuntu banner, then goes dark, never to return.
