Description
Mutter is a Wayland compositor and X11 compositing window manager based on the Clutter toolkit. GNOME Shell is GNOME's signature desktop, and is built on top of Mutter.
In this presentation, I'll start with a quick overview of various aspects of Mutter internals, such as:
- The different abstractions layers for rendering the scene graph (Clutter, Cogl, Graphene)
- GBM/EGL native renderer
- Ongoing transition to atomic KMS
- Usage of hardware planes, and the challenges of assigning planes
- Nesting compositors with an X11 / Wayland hybrid
- DMA-BUF based screencasts with PipeWire
After that, I'll cover ongoing changes, as well as future plans. Some of these topics are:
- Experimenting with
libliftoff - The path to atomic modesetting
- Plane assignment
- Support for DMA-BUF modifiers in PipeWire
- Usage of modern OpenGL features in Cogl (UBO)
- Vulkan API on a compositor
Ideally, we will be able to create a proof-of-concept branch of Mutter using libliftoff; a proof-of-concept branch of PipeWire with better DMA-BUF support; and understand what's missing / what's feasible to implement Vulkan-based rendering.
