The laptop was still on the Hyprland-era Pantheon commit while the desktop moved to KDE Plasma 6 + Limine and split system.nix into focused modules. This brings over everything that isn't hardware, unchanged, so both machines stay diffable: - Plasma 6 on Wayland with SDDM, Konsole, gruvbox icons, KDE MIME defaults (replaces Pantheon/LightDM; libreoffice-qt6 replaces the GTK build) - Limine bootloader with the gruvbox theme, replacing systemd-boot - system.nix split into boot/networking/locale/nix-settings/security - flakes + nix-command, sysctl hardening extras (yama, tcp_timestamps), geoclue off, captive-portal probe off - package parity: obs-studio, lmms, go, qemu, KDE utilities, lean SDR++ and rtl_433 overrides with hardware.rtl-sdr Hardware and power are adapted rather than copied: - hardware.nix keeps the AMD 680M + RTX 4050 PRIME offload setup, asusd and supergfxd, v4l2loopback webcam and the DualSense ERTM fix; OpenRGB and the desktop's single-GPU block are dropped, keyboard lighting is asusctl - power.nix is new: power-profiles-daemon for Plasma's profile switcher, lid-close handling via the current logind.settings.Login spelling, powertop/acpi, notes on asusctl charge limits - no acpi_enforce_resources=lax, ACPI owns the EC asusd drives here - touchpad defaults, and firewall openings so the hotspot script's shared connection can hand out DHCP/DNS - pinentry-qt instead of the desktop's leftover pinentry-rofi, blueman dropped in favour of Plasma's bluedevil hardware-configuration.nix stays tracked here (unlike the desktop, which gitignores it) since it's the only record of this machine's disk layout.
