Not surprisingly, Dell wants to be able to ship a wide variety of hardware with their Ubuntu PCs. But many components are just not supported well enough in Linux.
ATI’s graphics cards are either supported very poorly, or not supported at all on Linux. Now that Dell says they want to ship ATI graphics, does this mean they will really pressure ATI? Could an ATI driver with AIGLX compositing finally arrive?
Dell wants to offer ATI Linux systems, but first the driver must be improved for the Linux platform (not necessarily open-source, but improved). Dell currently ships desktop Linux systems with Intel using their open-source drivers as well as NVIDIA graphics processors under Linux.
