 # Andy Ritger - Enabling Alternative Window Systems with a non-Mesa Graphics Driver Implementation
 
 Alternates to the X Window System, such as Wayland and Mir, have evolved
 through novel use of the building blocks of the Mesa-, DRI-, and DRM-based
 Linux graphics driver stack.
 
 We have been working to support alternative window systems in the NVIDIA 
 Linux Graphics Driver through:
 
 * Refactoring our driver stack to more closely align to the organization
 assumed by these alternative window systems (e.g., by working to plug
 into DRM-KMS).
 * Proposing new EGL extensions that alternative window system
 implementations can use to enumerate GPUs, correlate objects between
 EGL and DRM-KMS, and present frames through EGL + DRM-KMS.
 
 In this talk, I will describe the work NVIDIA has been doing to prepare
 to plug into DRM-KMS, present the EGL_EXT_device_* and EGL_EXT_output_*
 family of extensions:
 
 * [EGL_EXT_device_base](http://www.khronos.org/registry/egl/extensions/EXT/EGL_EXT_device_base.txt)
 * [EGL_EXT_device_drm](http://www.khronos.org/registry/egl/extensions/EXT/EGL_EXT_device_drm.txt)
 * [EGL_EXT_output_base](http://www.khronos.org/registry/egl/extensions/EXT/EGL_EXT_output_base.txt)
 * [EGL_EXT_output_drm](http://www.khronos.org/registry/egl/extensions/EXT/EGL_EXT_device_drm.txt)
 
 and suggest an EGLStream-based mechanism to present frames to an [EGLoutput](http://www.khronos.org/registry/egl/extensions/EXT/EGL_EXT_stream_consumer_egloutput.txt)
