Dual monitor laptop question

I have a Toshiba Satellite S1762, with an ATI Radeon Mobility 7000 IGP card, and a Magnavox 15" LCD screen (Separate from the laptop) that I'm trying to get in a dual monitor set up. I'm using SuSE 10.1. After having already booted SuSE 10.1 and after logging in, I screw in the Magnavox to the VGA port on the back of the laptop, and I turn the Magnavox on, and now X Windows shows up magically on both the laptop LCD and the Magnavox LCD. However, if I restart X Windows, then my X Windows will get pushed to the Magnavox and the laptop screen will go blank. But, if I press ctrl + alt + F1, the terminal shows up on my laptop while the Magnavox pops up a box saying "Attention: No signal"

I've tried using the "Activate Dual Head" mode and using "Clone display" as a config, but it sticks to one monitor while the other is off. Like I said, anytime I restart X windows, it pushes it to the other screen and turns off the laptop screen. Is this some kind of config file I need to fix, or some kind of setting? My guess is that I'd have to do something with the X config files, but I'm completely lost as to what.

I am NOT using any special kind of graphics driver for the ATI card, not quite sure which one I'd use. Any help offered will be greatly appreciated!

The 10.1 release notes made some type of comment about dual-head not being supported on ATI cards. Check that out. 10.2's rel notes lack the same comment, but I think there have been other problems with ATI cards on 10.2. Check the bugtracker at and the other usual places.

It seems that ATI just has very little interest in helping the open source community; thus my loyalty has switched to Nvidia, who is great.

I'm having the same problem with openSuSE 10.2 and Radeon Mobility 9100 IGP (5835). This chip is a real piece of crap :-((
