> Cloning it is required, no? I'm actually not sure if you need to clone it at all. At least with the ATI driver you can just use the accelerant twice. If you compile and run the SlimDemo (./graphics/SlimDemo) you should get a black and white screen but the app_server will still be running and switching to a workspace with a different resolution (or the ctrl-shift-option-command-whatever f12 thing) will bring your desktop back. If it's not possible to use the accelerant directly, you should be able to build something from the SlimDemo. I don't remember how exactly, but I had the first accelerated Haiku window right under R5 with the app_server still running. It either used SlimDemo as basis or the AccelerantHWInterface directly.
