Ensure the udisks2 service is enabled so it starts at boot, before SDDM:

Outlines responsibilities, internal procedures, and requirements for UDOT staff and consultants.

The second component, , addresses the technical heart of the issue. Traditional models operate on syntactic relationships—they see numbers and categories but not meaning. An SDDM, by contrast, incorporates ontologies, knowledge graphs, and context-aware embeddings. It understands that "hot" in a weather dataset means something different from "hot" in a supply chain for refrigerated goods. By explicitly encoding these semantic layers, the model can reason analogously to a human expert. When combined with Udot, this means that a user can ask the model why a decision was made, and the explanation will be given in the user’s own conceptual language—not in SHAP values or feature importance scores that only a data scientist can parse.

By default, udisks2 can restrict actions at the login screen for security. If you need SDDM to perform disk actions (rare, but possible for custom kiosk setups), you need to configure PolicyKit.

Establishes uniform procedures for designing box culverts, retaining walls, and headwalls.
