My radeon mergedfb driver supports this. it is in DRI CVS and is available in the DRI binary snapshots: http://dri.sourceforge.net/snapshots/ Just sput together a working Mergedfb setup, and then start X. if you have an external monitor attached, X will start with your dualheaded setup. if it finds no monitor, it will use a single headed setup. As an added bonus HW accelerated 3D will work on both heads as well. More info on radeon mergedfb: http://bugs.xfree86.org/show_bug.cgi?id=276 http://www.botchco.com/alex/radeon/mergedfb/cvs/DRI/final/radeon.4.html Let me know if you hve any problems, Alex ---------- Hi! I've got a notebook with second head capability. I managed to have my second head working OK, but I have two layouts in my XF86Config-4, one describing a single head setup, and one the two-head setup. I was wondering if the X server had a way to detect that a second monitor is plugged in or not, and choose a layout based on that. What I'd like is : - not reboot the notebook - just restart the X-server (logging out is OK). GFX: radeom M6 LY kernel: 2.4.22-ac2 XFree86: 4.3.99.11 At boot time, the fradeonfb detects the presence/abscence of a second monitor, but will not update this at runtime. Is there a way to do this?
