COSMIC logs in and runs on a ThinkPad, with first steps on Bluetooth

Solnix now runs a desktop on real hardware. On the maintainer's ThinkPad X1 Extreme Gen 5 (Intel Iris Xe, Alder Lake-P) it boots to a graphical login (greetd with cosmic-greeter), and logging in brings up the full COSMIC 1.5 session: the compositor, panel and applets, launcher, app library, workspaces, background, notifications and the terminal. Logging out returns to the login screen. Every frame is drawn by the GPU: the i915 driver port drives the panel and Mesa's iris driver renders, and the compositor logs which renderer it uses, so a quiet fallback to software rendering would show. This supersedes our 2026-10-27 item, which said the desktop did not yet draw a frame. Since then: the touchpad works (new I2C HID drivers), the launcher finds the 55 installed apps with their icons, wifi (Intel AX211) joins a WPA2 network at boot, and a run of fixes ended greeter stalls and a file-descriptor leak that stopped the login screen after about eight hours. It is now the maintainer's everyday boot environment. Bluetooth has started: the AX211's Bluetooth firmware loads and the controller answers commands (it reports HCI 5.3) on every cold boot tested, and NetBSD's Bluetooth core is ported to run in userland. Pairing does not work yet; the stack hasn't been brought up on the hardware. Also new: Firefox ESR 153.6 builds for Solnix, Wayland-only, telemetry off; it hasn't been run on the desktop yet. What does not work yet: screen lock, the battery, sound and network applets, suspend, and audio beyond a basic playback check. There is no graphical install image, so this is not something you can download today; it runs on one laptop. AMD and NVIDIA graphics don't run yet. The packages the desktop is built from (COSMIC, Mesa, greetd and their dependencies) are signed and in the binary cache.
