May 2026 performance summary focusing on multi-monitor reliability, clone display capabilities, and security hardening for user management. Key features delivered: - Clone/copy display mode support in Treeland compositor with a new virtual output protocol; integrated into DisplayWorker::switchMode() and updated monitor grouping to leverage virtual outputs for cloning. - Robust multi-monitor scale handling in extend mode: automatic layout recalculation on scale changes, two-step position updates to prevent crashes during rapid configuration changes, and shared display position logic extracted for maintainability. - Per-monitor scale persistence across logout/login achieved by stabilizing watchers and update flows for scale factors. Major bugs fixed: - Display scale and layout instability in multi-monitor extend mode when scales change or configurations are modified rapidly; fixed by immediate local updates plus delayed backend commits. - Persistence of display scale after logout/login to ensure user preferences survive sessions. - SetPassword DBus API lifecycle hardened: deprecated to prevent insecure usage, then restored with admin authentication (polkit) to secure user creation and prevent unauthorized password changes, while preserving a chpasswd injection guard. Overall impact and accomplishments: - Significantly improved multi-monitor usability and reliability under dynamic reconfigurations, enabling smoother workflows for power users and admins. - Strengthened security posture for user management workflows without breaking essential functionality. - Improved maintainability and developer productivity through refactoring to Qt Wayland Client Extension wrappers, virtual output support, and streamlined build tooling. Technologies/skills demonstrated: - Qt Wayland Client Extension, Wayland protocol wrappers, and migration of wrappers to modern Qt patterns. - Multi-monitor layout algorithms (ConcatScreen) and robust state management for real-time display changes. - DBus watcher lifecycle improvements and polkit-based admin authentication integration. - Build-system modernization (qt_generate_wayland_protocol_client_sources) and modularization of virtual output handling.
