feat: Gaming on NVIDIA is not offered any more, the SteamOS conversion covers NVIDIA PCs

Browse Source 
The conversion installs the patched gamescope on every NVIDIA PC and sets up the kernel parameters, suspend memory and 32-bit libraries on a supported card; it turns off an existing Gaming on NVIDIA.

## 2.11.2 - 2026-10-13
- **feat: the SteamOS conversion is offered on NVIDIA PCs again (GTX 16 / RTX 20 series or newer: Turing and later, the cards NVIDIA's open kernel driver supports): it builds and installs a patched gamescope from [steamify-gamescope-nvidia](https://github.com/theupriser/steamify-gamescope-nvidia) (GBM-allocated scan-out buffers, NVIDIA's corrupted gaming-mode picture, gamescope#2309; a few minutes to build) and sets `gamescope_drm_gbm_scanout=1` for the session (`lib/gamescope-nvidia.sh`). On those cards it replaces "Gaming on NVIDIA" (kernel parameters, early modules, suspend memory and the 32-bit libraries come with it); "Gaming on NVIDIA" is only offered on older NVIDIA cards, or while it is on (turn it off or swap it for the conversion; the two exclude each other); single user mode works with either. Tested on an RTX 5080 (driver 615.78.08): Steam's gaming UI is clean with it and shows artifacts without. The package is pinned to one gamescope release: updating it is not automatic yet**

It replaces "Gaming on NVIDIA", which is not offered any more (the kernel parameters, early modules, suspend memory and the 32-bit libraries come with the conversion on a supported card; a PC that had "Gaming on NVIDIA" on has it turned off when the conversion is turned on).

- **feat: "Gaming on NVIDIA" also keeps video memory over suspend (`NVreg_PreserveVideoMemoryAllocations=1` in `/etc/modprobe.d/90-steamify-nvidia.conf`, the initramfs is rebuilt), enables `nvidia-suspend`/`nvidia-resume`/`nvidia-hibernate`, and installs `lib32-nvidia-utils` and `lib32-libxkbcommon` (32-bit games, the 32-bit MangoHud preload) on a supported card; off removes only what Steamify added. Untested on hardware yet**
