Hey everyone,
I've been thinking about submitting a Wayland-themed talk to the FOSDEM
graphics devroom [1] and wanted to check with the community if anyone
else has considered this or another Wayland topic and whether you think
it would be a good idea™.
What I would want to talk about is a beginner's introduction to Wayland
from the client perspective. I think that resources on this (and on
Wayland in general to be honest) are quite scarce and that I could pass
on some of the knowledge I have gained by implementing native Wayland
support in Kodi this way.
This would include stuff such as:
* Wayland architecture
* Comparison with X
* Security architecture
* Limitations: What is not possible with Wayland (currently)
* Difference between core and extension protocols
* Global registry
* Relevant documentation and resources
* Why you should not be writing a Wayland client yourself (aka use
toolkits if possible)
* Relevant compositors to test on and how to use nested mode
* Basic client programming
* Protocols needed to get a surface on screen (wl_compositor,
wl_surface, wl_shm, wl_shm_pool, wl_shell, wl_shell_surface)
* Seats and input
* Keyboard: wl_keyboard and libxkbcommon
* Mouse: wl_pointer and libwayland-cursor for cursor handling
* xdg_wm_base
* Window decorations
* EGL
Possible extensions/replacement topics:
* Bindings (just mention: C++, D, Java, Rust)
* Vulkan (I think EGL is more relevant at the moment)
* Some more extension protocols such as pointer-constraints and
relative-pointer (relevant e.g. for games)
* Subcompositing
* ...
I would not include:
* Details of libwayland API (e.g. proxy wrappers)
* Every extension protocol or even core protocol object just for
completeness
* Historical baggage such as xdg_shell v5
* EGL/Mesa internals
I'd love to hear any comments/suggestions you might have and generally
what kind of topics people would be interested in.
