Server Kernel Mode Setting (KMS) Drivers
Many servers ship with only basic GPU hardware. Despite the basic nature of such hardware a fully fledged X.org driver has historically still been required to manage it. Fedora 18 introduces Kernel Mode Setting (KMS) drivers which provide enhanced support for the GPUs commonly found in servers. Users of these GPUs are now able to utilize the additional features provided by KMS drivers, including enhanced graphics in virtual consoles. Chipsets supported by these new KMS drivers include AST and MGA-based ServerEngines.
GPU Hot Plug Support
The X.org server has been rewritten to support 'hot' plugging and unplugging of GPUs. Specifically, this allows Fedora to provide better support for USB connected graphics devices exposed by many modern systems and laptop docking stations.
