KEYWORDS:
|
||||
|
||||
Wayland is a nano display server, relying on drm modesetting, gem
|
||||
batchbuffer submission and hw initialization generally in the
|
||||
kernel. Wayland is compositing manager and display server in one
|
||||
process. window management is largely pushed to the clients, they
|
||||
draw their own decorations and move and resize themselves,
|
||||
typically implemented in a library. more of the core desktop could
|
||||
be pushed into wayland, for example, stock desktop components such
|
||||
as the panel or the desktop background.
|
||||
|
||||
It is still designed with a windowed type of desktop in mind, as
|
||||
opposed to fullscreen-all-the-time type of interface.
|
||||
|
||||
Current trends goes towards less and less rendering in X server,
|
||||
more hardware setup and management in kernel and shared libraries
|
||||
allow code sharing without putting it all in a server.
|
||||
|
||||
Client allocates DRM buffers, draws decorations, and full window
|
||||
contents and posts entire thing to server along with dimensions.
|
||||
|
||||
Everything is direct rendered and composited. No cliprects, no
|
||||
drawing api/protocl between server and client. No
|
||||
pixmaps/windows/drawables, only surfaces (essentially pixmaps). No
|
||||
gcs/fonts, no nested windows. OpenGL is already direct rendered,
|
||||
pixman may be direct rendered which adds the cairo API, or cairo
|
||||
may gain a GL backend.
|
||||
|
||||
ISSUES:
|
||||
|
||||
Include panel and desktop background in wayland?
|
||||
|
||||
How does clients move their surfaces? set a full tri-mesh every time?
|
||||
|
||||
How does the server apply transformations to a surface behind the
|
||||
clients back? (wobbly, minimize, zoom) Maybe wobble is client side?
|
||||
|
||||
How do apps share the glyph cache?
|
||||
|
||||
Input handling - keyboard focus, multiple input devices, multiple
|
||||
pointers, multi touch.
|
||||
|
||||
Drawing cursors, moving them, cursor themes, attaching surfaces to
|
||||
cursors. How do you change cursors when you mouse over a text
|
||||
field if you don't have subwindows?
|
||||
|
||||
synaptics, 3-button emulation, xkb, scim
|
||||
|
||||
RMI
|
||||
|
||||
the get_interface method is called on an object to get an object
|
||||
handle that implements the specified interface.
