…imits The xrandr refresh rate cap never worked on Wayland (mutter only generates 60Hz modes for virtual displays, xrandr --rate silently fails). Remove the broken display.yml, refresh rate script, and autostart entry. Add FreeRDP apt pin (ubuntu0.4 confirmed stable, ubuntu0.3 had heap corruption), PAM nice limits so the handover daemon can run at Nice=-10, and remove dangerous auto-restart of gnome-remote-desktop.service which crashes active RDP sessions.
Deploy gnome-remote-desktop 49.0-0ubuntu1.1hyperi1 which adds a max-framerate gsettings key to cap PipeWire screencast framerate. Stock GRD 49 hardcodes 60fps — this halves software encoding load on virtio-gpu VMs without hardware video encoding. - Add grd_patched.yml task to deploy and pin the patched deb - Set max-framerate=30 via system dconf profile - Add grd_patched_version default variable - Verified on desktop-derek: PipeWire stream shows maxFramerate 30/1
Adds Rust build optimisation tools to the developer_core Ansible role: - sccache: shared compilation cache across projects - cargo-sweep: build artifact cleanup - mold: fast linker for native x86_64 builds (5-10x faster linking) - Global ~/.cargo/config.toml with sccache wrapper, mold linker, jobs=8 All tools support Ubuntu, Fedora, and macOS. macOS config omits mold linker flags (uses default linker) but still gets sccache and jobs=8.
