Project Status: No Longer Under Active Development
This project was an experiment to integrate WPE into the Balena Hub.
It is not currently actively developed or maintained. The current
version available from Balena Hub does not reflect the most recent
advancements or patches in the WPE ecosystem.
If an up to date Balena block is very important to you, we'd be very interested to hear more. Meanwhile, if you encounter issues or are seeking updates, we recommend exploring alternative solutions or resources that align with your requirements.
Should you have any further questions or inquiries, please feel free to get in touch.
Weston is the reference implementation of a Wayland compositor, as well as an useful environment in and of itself.
Out of the box, Weston provides a very basic desktop, or a full-featured environment for non-desktop uses such as automotive, embedded, in-flight, industrial, kiosks, set-top boxes and TVs. It also provides a library allowing other projects to build their own full-featured environments on top of Weston's core.
The core focus of Weston is correctness and reliability. Weston aims to be lean and fast, but more importantly, to be predictable. Whilst Weston does have known bugs and shortcomings, we avoid unknown or variable behaviour as much as possible, including variable performance such as occasional spikes in frame display time.

...There are several environment variables that can be used to tweak the Weston settings. The defaults should be okay for most cases.
| Environment variable | Options | Default | Description |
|---|---|---|---|
WESTON_IDLE_TIME |
integer |
0 (never) | Idle time in seconds (e.g. 900) |
WESTON_SHELL |
string |
desktop |
The shell to use (desktop, fullscreen, kiosk etc.) |
WESTON_OUTPUT_USE_CURRENT_MODE |
0, 1 |
0 |
Inherit the display mode from KMS console |
WESTON_OUTPUT_MAX_WIDTH |
integer |
0 |
Maximum horizontal resolution the compositor may set |
WESTON_OUTPUT_MAX_HEIGHT |
integer |
0 |
Maximum vertical resolution the compositor may set |
The maximum-resolution environment variables rely on the list of modes
advertised by the DRM subsystem. That means if you set for example the
maximum horizontal resolution to 1920 and the list contains 3840x2160,
2560x1440, 1920x1080 and 1280x800, 1920x1080 will be picked.
The shell used will be ${WESTON_SHELL}-shell.so. You can use any shell
shipped with Weston by default.
