Another option that worked for a radeon user I was helping, was to set up the video chip in mergedfb mode initally with crt1 forced on or with the monitor attached. then use xrandr to resize the frame buffer on the fly. so if you have two 1024x768 heads set up the initial framebuffer as 2048x768 then use xrandr to resize to 1024x768. if you plug in the monitor rerun xrandr and change back to 2048x768. this only works in mergedfb mode and may not work on sis (I don't know that
You bet it does :)
any one has tried it).
_I_ do actually test the code that I publish (which is something not everyone does according to my experience) :)
