I hadn't noticed that this feature is called "DDC". I still haven't gotten it working like I would want it to, so I guess I'd need to play with the modes some more, but then again that's OK since I'm not desperate to use this particular feature on two mismatched monitors anyway. > Here is some discussion from the Matrox forum via Google's cache regarding > the detection problem (Ben is/was the only one of their moderators that had > a brain): > > http://216.239.39.100/search?q=cache:W02FxzA7OjEJ:forum.matrox.com/mgaforum/Forum2/HTML/001921.html+matrox+%22noDDC%22&hl=en&ie=UTF-8&client=googlet > It talks about VBE (VESA BIOS Extensions), so it sounds like a standards problem. If XFree86 would skip the VESA BIOS (like the Linux kernel skips the system BIOS) this probably wouldn't be an issue.
