I haven't had a look at this, since well, I don't have a G400 for one, and what I have heard hasn't been pretty from a drivers writer perspective. Discussions on other lists I follow have led me to believe that mutlihead is availible with a number of restrictions. You have to use 16 or 32 bpp modes, no others are availible (I don't know if you can have different layouts on different monitors, but I think you can) your max dclk is split in half, ie, from 310 to 155 on most cards. also, from a programming perspective, you still have one card, one memmory, one accel engine, one warp engine, but two crtc's (including extended crtc registers) I believe we sould need a way for kgi to manage onboard memory even for the framebuffers here, and look into having one card activated but with multiple sets of private data to manage something like a kgi_<subsystem>_mode struct... anyway, it's not high on my list of priorities, and i'm not even concidering it until kgi 0.9 and when I get a G400 myself :) I'll polish up the code, put the copyright notices back in where they belong and such, and I'll put the code up on http://194.218.183.235/~wlfshmn/ within a couple of hours, since I have some biology homework to help my sister with :) Johan Karlberg
