In short: such a scenario is completely unsupported. > How in the world would I set that up properly? > --fbmm does only allow a global setting, and does not seem to do > anything anyway (tried 400x100 as a parameter, with no changes). > --dpi also is only global, but does not even allow different settings > for horizontal and vertical. This is because the Xserver has only the notion of number of pixels and screen size in cm. DPI can be calculated by these values, thus you either set framebuffer size in cm or dpi, the other one comes for free. Also note the singular (screen size in cm). There's no such thing as different dpi values per output. Would require even protocol changes (what do you do if your window is for ones half on one screen and one half on the other?). Besides - why would anyone want to use 1024x768 on a 16:9 projector?!? Or does the projector really have an anamorphic lens?
