modules/user/nvidia.sh detects the card via lspci and installs the branch
that matches it: current (Turing+), 580xx (Volta/Pascal/Maxwell), 470xx
(Kepler), 390xx (Fermi); pre-Fermi is refused with an explanation.
- no prompt for a detected GPU (--nvidia=no is the opt-out, wired in setup.sh)
- Secure Boot gate: with enforcement on, the akmods key is generated and
imported and the module stops BEFORE installing the driver, so nobody gets
the documented unsigned-module black screen; off/setup-mode skips signing
entirely (a MOK import is never processed when enforcement is off)
- bounded wait for the kmod build, so a reboot cannot land mid-build
- dnf mark user on the akmod; VA-API/vulkan offered as an opt-in extra
- never sets nvidia-drm.modeset=1 (RPM Fusion enables KMS; the flag conflicts
with Fedora's simpledrm patch)
- branch chosen from the chip family in the PCI name, not the device-id
ranges, which overlap between families
Tested with a stub harness (38 assertions, 14 scenarios): all four branch
mappings, multi-GPU warning, Optimus, pre-Fermi refusal, SB on/off/setup,
unparseable name fallback, idempotent re-run, build timeout.
