systemd service

A systemd user service is configured to assist with automated environments such as cloud-hosted simulations or for multi-user environments. The service requries that the appropriate DISPLAY and XAUTHORITY environment variables are set -- keep in mind that user services do not start from a shell and do not automatically in herit these values.

systemctl --user start svlsimulator

This service will automatically apply any environment variable set in ~/.local/svlsimulator/env-lgsvl.

The default values are as follows:

LGSVL__SIMULATOR_PORT=8181
DISPLAY=:0   # only set if lgsvl_service_use_local_display is 'true'
XAUTHORITY=~/.Xauthority

Variables

• lgsvl_install_root_directory installation directory. Will create the subdirectory svlsimulator. Defaults to /opt
• lgsvl_service_use_local_display will use the default value DISPLAY=:0 when the service starts. This may be overridden by the environment file.
• lgsvl_service_port_map will allocate user ports, starting at 8182, for each user who runs this script. The port map is stored in the installation root directory, and the user's environment file is configured to use this port. If false, no port map is created. Defaults to true.
• lgsvl_env_xauthority: the path to the .Xauthority file for this user to write to their environment file. Defaults to ~/.Xauthority.
