The problem is that 17" TFT screens with 1280x1024 in dualhead setups
are also becoming quite common. Given the limitation of ATI R200 and
R300 cards, which have a maximum 3D framebuffer of 2048x0248, it's
impossible to use dualhead in combination with XGL or AIGLX in
fullscreen, which means GL compositing is impossible.
For games you switch to single-screen to play it for fullscreen on these
cards, for desktop setups that is just not workable.
