Problems with connecting CRT Monitor

[psyche]

HI
I have just tried to connect a CRT Monitor to my laptop which runs ATI Radeon X700 with ati-drivers.
When I boot my machine everything is fine. The image is on the CRT Monitor only and looking good. But as soon as I start x.org, the picture is on both the CRT and LCD, and the picture on the CRT goes outside the screen(althogh it is a 17" monitor and the res is 1280x1024 - this worked in Windows) and there are some strange lines going through the picture at the top of the screen. Anyone know whats the issue here???

What kind of laptop you have? can you post your xorg.conf ?
