Default dvi+vga dual-screen woes

Okay, I have two monitors, both LCDs. One is a Dell 15" with only a VGA input and other is a Sceptre 20" widescreen with both vga and dvi. I want to use both, but they won't play well together. The only way for both to be active is to have them both running through VGA (using the dvi->vga adapter), booting with one in vga and the other DVI yields both blank screens. The problem with booting with both in VGA is that the screen is squished on the Sceptre and the OSD couldn't fix it. This with Ubuntu and an eVGA Geforce 6200.

Please start X with the following command:
startx -- -logverbose 5

and then generate and attach an nvidia-bug-report.log.

Thanks,

There is no way to execute such a command, sunce both screens are blank (no signal) while the machine is booting (before or after POST).

Here's what eVGA says: "The maximum digital resolution for your card is 1600x1200, and it will not display 1680x1050 from the DVI. The Scepter display is an HD display, which has no EDID protocal to communicate properly with your video card. To use this monitor at its native resolution, you will need a video card which supports HDTV."

How can that be? Isn't the limitation in the resolution due to its ability to process the number of pixels? 1680x1050 is 1.764 million pixels, which is less than 1600x1200's 1.92 million. And this doesn't explain why it doesn't display anything at startup or why the analog monitor also remains blank. Anyway, what they're saying is definately wrong since it IS displaying a full 1680x1050 image through DVI, just not when an analog monitor is added.

You'll need to find a means of generating the bug report that I requested. Surely whatever Linux distribution you're running has some means of booting that doesn't require X.

Thanks,
