Introduction

Weston is the official implementation reference of Wayland open source display protocol, and Weston 9.0(or 8.0).

There are multiple ways to configure StarFive Buildroot SDK Weston:
  • Command line options: That is, the options of the command when starting Weston.

    The following code block provides an example. 

    weston --tty=2
  • Configuration file: The weston.ini configuration file.

    The configuration is located in /etc/xdg/weston/weston.ini, corresponding to the location of SDK code: buildroot/package/weston/weston.ini.

    Please refer to: https://fossies.org/linux/weston/man/weston.ini.man.

  • Special environment variables
    Generally, these environment variables are set in these places:
    • The start-up script of Weston, in /etc/init.d/rc.pvr of the SDK firmware.
      The following code block provides an example. 
      # /etc/init.d/rc.pvr start
...
export WESTON_DRM_MIRROR=1 # should be set before starting
Weston
...
weston&
    • The environment script of Weston, in /root/run_weston.sh of the SDK firmware, corresponding to the location of SDK code: buildroot/package/weston/run_weston.sh.
  • Dynamic configuration file:

    For DRM back-end, Buildroot SDK Weston provides some dynamic configuration support, such as dynamic display configuration files, the default path is /tmp/.weston_drm.conf. The dynamic configuration can be specified by the environment variable WESTON_DRM_CONFIG.

  • udev rules: Some configuration of input devices in Weston should be set by udev rules.
