# LACT configuration file
# The LACT config file is located in /etc/lact/config.yaml,
# and contains all of the GPU settings that are typically edited in the GUI,
# as well as a few settings specifying the behaviour of the daemon.
# LACT listens for config file changes and reloads all GPU settings automatically,
# but daemon-related settings such as the logging level or permissions require a service restart (systemctl restart lactd).
# This configuration file provides a specific setting for the admin user and group that the daemon will use for permissions management.
# Instead of using "wheel" or "sudo", it creates a dedicated "lact" system user and group for this purpose, and specify them in the config file.

%description
%if %{with headless}
LACT (Linux GPU Configuration And Monitoring Tool) is a daemon and CLI
utility for GPU configuration and monitoring. This headless variant includes
only the daemon and CLI, suitable for servers and minimal installations
without graphical dependencies.
%else
LACT (Linux GPU Configuration And Monitoring Tool) provides comprehensive
GPU control with a graphical interface. Features include power management,
fan curve configuration, overclocking, and detailed monitoring with
historical graphs.
%endif

Post-installation/uninstallation steps can be found in:
/usr/share/doc/packages/lact

DISCLAIMER, none of the SUSE maintainers are responsible if you mess up
your GPU by using this tool, especially the overclocking features.
Please be careful and understand the risks before using it.
