Current Status
Wayland protocol libraries and the reference Weston compositor are integrated as packages in the core-oe meta/ layer. The packages can be build against targets that accept mesa-dri. For example, intel-specific emgd drivers that override mesa-dri cannot be used to build Weston.
Enable Wayland in a image
The wayland compositor can be enabled by listing it as a DISTRO_FEATURE; there are two steps:
Enable building
- Wayland - If "wayland" flag in DISTRO_FEATURES is set, Mesa builds the wayland-egl platform
- Weston compositor -
- If "wayland flag in DISTRO_FEATURES is set, Weston will build with KMS support.
- Also, if X11 is enabled, as in the x11 DISTRO_FEATURES flag is set, weston will be build with X11 support.
The preferred way to enable building is
DISTRO_FEATURES_append = " wayland x11"
Enable installing in an image
To set installation in an image, you need to add the following parameters in conf/local.conf:
- CORE_IMAGE_EXTRA_INSTALL += "wayland weston"
Running Weston
To run Weston inside X11, simply adding weston to the image will be sufficient. Under Sato there will be a Weston launcher in the Utility category.
Wayland/Weston work in still developer-oriented. The best way to run them is through CLI. As we fine tune the way to run Weston and setting policies, scripts to automate this work will be provided.
Environment setup
Please do export XDG_RUNTIME_DIR:
- mkdir -p /tmp/$USER-weston
- chmod 0700 /tmp/$USER-weston
- export XDG_RUNTIME_DIR=/tmp/$USER-weston
Launch
- weston
Current working status
QEMU
Weston 1.0.3 will not run directly on the emulated QEMU hardware, due to lack of EGL support.
Weston will run under X emulation without issues.
Physical Machines
There is no embedded-class physical machine yet verified to run Weston to top of hardware. Current efforts focus on enabling FRI2.
Plan
- Upgrade Weston to a version that can run only on framebuffer (e.g. pixman)
- Image that boots Weston on KMS
- Enable GTK+ 3 Wayland support
- Enable Qt Wayland support
- Enable Clutter Wayland support
