i must admit that i am no genius at all when it comes to graphics and the technology behind the different parts of X.
i have a setup documented by the attached XF86Config-4 file as it runs on my Latitude C610 with a Radeon Mobility LY. it's dual head and works perfectly as such. i start it through xdm. nevertheless, it makes a difference to X whether an external VGA monitor (analog flatscreen) attached or detached. If it's detached, then X comes up just fine, displaying the second screen on the external monitor as soon as I plug it in (after it started). If the VGA cable is attached at the time of loading X, then my laptop flatscreen goes all funky (black and white, melting around the screen, constantly changing and giving me a general feel that it's not good for the display) and the external monitor stays blank. when i use the Fn-F8 combination to toggle the display, the second screen comes up on the external monitor in 640x480 mode. if i press Fn-F8 again, it comes up on both (as 640x480), and another press will just make it show on the laptop, this time without the weird white melting thingy. but it's 640x480, and i am wondering why it makes a difference whether the external screen is attached or detached. let me know if you need to see logfiles. thanks, -- martin; (greetings from the heart of the sun.) \____ echo mailto: !#^."<*>"|tr "<*> mailto:"; net@madduck "micro$oft productivity software" - see reductio ad absurdum, conclusions.
