The motd was the worst of it — it told anyone logging in that "WiFi and Bluetooth work with the firmware Fedora ships", which is precisely backwards for the onboard adapter, and pointed at a Windows partition this machine no longer has. What the blobs did fix, verified: the GPU initialises, ADSP/CDSP/SLPI all run, sensors appear as IIO devices, venus registers /dev/video0-3. What they did not, and why, so nobody repeats the search: Onboard WiFi is loaded by the modem — wlan*mdsp* is the WLAN Modem DSP — so ath10k_snoc binds and then waits silently on a QMI service that never arrives. The modem boots and dies at "RF stuck in QLINK start state", the RF front-end, which is board-specific wiring in a way the SoC-level blobs are not. These are Qualcomm *reference* drivers; good enough for the GPU and DSPs, evidently not for this machine's radio. Three plausible fixes that do not work are recorded too: rmtfs (correct to enable, does not help), the _nm firmware variants (rejected at PBL), and unplugging the USB dongle (different bus entirely — it was never competing). Audio gets further than expected. The codec answers over SLIMbus with its chip id, so hardware and ADSP are fine; what fails is the codec's SoundWire block declaring two data-in ports where the controller expects six. That is a kernel mismatch and needs a kernel change. Also record the mesa caveat properly: the GPU works, but freedreno's EGL path segfaults gnome-shell into a login loop, and LIBGL_ALWAYS_SOFTWARE does nothing because mutter uses EGL. MESA_LOADER_DRIVER_OVERRIDE=kms_swrast is what works. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XWRjNJMistCy6ngXH5aJLS

No per-model Qualcomm firmware ships in this image — it is not

redistributable. Supply it to get accelerated graphics, audio, the sensor

hub and hardware video decode: see docs/firmware.md, or run

`sudo c630-firmware` if this machine still has its Windows partition.

Onboard WiFi additionally needs modem firmware that no public source

provides. Use a USB dongle or tether a phone over USB.
