Can't install Debian / Ubuntu - monitor issue

September 16, 2011 at 07:06:29
Specs: Debian 6 - Ubuntu (recent versions), Intel P4 / 4 GB
I'm trying to install Debian 6 on a Dell Optiplex GX280 with an nVidia GeForce 8400GS video card and a 21" Dell flatscreen monitor. Note : I have also tried installing various Ubuntu versions and derivatives, usually based on Ubuntu 10.04 - 11.04 with the exact same problem.
I proceed through the installations without any problems or error messages (and again, note : with Ubuntu based Live sessions, the Live sessions load properly at the proper 1600x1200 screen resolution) and afterwards, if the GRUB menu loads (something I've only seen in the Debian 6 install) and proceeds to load the OS (and these installations are with Debian / Ubuntu as the only OS on the drive), the flatscreen goes into power saver mode.
It was my understanding that recent versions of Debian / Ubuntu no longer use xorg.conf, so I can't check for wrong / incorrect / misconfigured settings in that file.
My question is : is there some fundamental step that I'm missing in these installations, that they all end the same way, with the monitor going into power save mode? And more importantly, what can I do to fix it? I'm more than willing to Google the issue, but my research so far has been unproductive.
Thanks to anyone who's willing to help.

Maybe try this first. When you boot to a normal install see if the session can be switched. Press and hold the alt key and try a few of the F keys. Try the F1 key.
It should display a text. Does it?

Might be an issue with bios and the video card also.

Since the live env works it may be useful to go back and harvest clues as to how that is working.

I peeked at the ubuntu site but didn't see anything right away. You might review that again in detail to get more ideas. Ubuntu site wiki and forums usually have a common problem.

(might be just the 1 key maybe too.)

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.
