+no fix known). The kernel parameters `nvidia-drm.modeset=1`/`fbdev=1` and loading the NVIDIA modules early don't change it
+(the driver already reports both `Y`), and gamescope started nested inside KDE artifacts too when KWin hands its fullscreen
+window straight to the display. What does work on an RTX 5080: Steam's Big Picture (`steam -gamepadui`) as a normal window of
+the Plasma desktop session, smooth and clean.
+
+So with an NVIDIA GPU (PCI vendor 0x10de, display class, its driver providing `nvidia_drm`: `nvidia_present`) the SteamOS
+conversion (`gaming`, and its options `boot`, `single`, `glyphs`) isn't offered, unless it is already on (so it can be turned
+off). `nvidia` ("Gaming on NVIDIA", `lib/nvidia.sh`) takes its place, hidden while the conversion is on (both would start
+Steam at login): it installs `steam` when missing (recorded in state `nvidia`, removed again only then) and enables the user
+unit `steamify-steam-autostart.service` (`services/`, `ExecStart=/usr/bin/steam @ARGS@`, Plasma only). Its sub-option
+`bigpicture` ("Steam starts in Big Picture", ticked along with it) rewrites the unit with `-gamepadui` and sets
+`ksmserverrc [General] loginMode=emptySession` (`kset`, undone with `krevert bigpicture`), so windows of the last session
+(Discord, a browser) aren't restored on top of Big Picture; unticked, Steam starts in its normal window. The opt-in sub-option `nvsilent` ("Start Steam silently") rewrites the unit with `-silent`
+(tray only); it and `bigpicture` exclude each other. The PC always boots into the desktop: there is no gamescope session. Takes effect at the next
+login.

+check, `vram_nvidia_legacy_id`; `nvidia_supported`) enabling it also does what NVIDIA's DRM stack wants, though it didn't cure
+gamescope: `nvidia-drm.modeset=1 nvidia-drm.fbdev=1` on the kernel command line (Limine, systemd-boot or GRUB; the file is
+backed up first; on Limine into the existing `KERNEL_CMDLINE[default]="..."` or `+="..."` line, never an extra appended line,
+which ends up as text; the kernel treats `nvidia_drm` and `nvidia-drm` alike) and
+`/etc/mkinitcpio.conf.d/90-steamify-nvidia.conf` (`MODULES+=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)`), then the initramfs
+and boot entries are rebuilt and checked for the parameters. The early-load drop-in is only there while every installed kernel
+has the NVIDIA modules (mkinitcpio fails on a missing module, and `limine-mkinitcpio` then skips that kernel's boot entry):
+a pacman hook (`/etc/pacman.d/hooks/85-steamify-nvidia-initramfs.hook`, after DKMS, before the initramfs is built) runs
+`/usr/local/libexec/steamify-nvidia-initramfs` at every kernel or driver change and decides again. Turning it off removes

+`--options` turns on exactly the listed items (the menu's ids: `gaming`,
