Jellyfin Desktop hard-sets mpv's hwdec=auto-copy, whose probe list leaves
out V4L2 M2M, and the Flatpak can't see the Frame's V4L2 decoder. An
LD_PRELOAD shim (preloaded straight from the store, only that path exposed
read-only) rewrites hwdec to v4l2m2m-copy,auto-copy; devices=all makes the
decoder visible. Overrides via nix-flatpak, or a home-manager-owned override
file without it.
steamFrame.dashboard.frameControls: a long press (longPressMs, default
1.5 s; a ring shows the progress from half of it) on a control under a
dashboard window or on a More Options (three-dot) menu row opens a popup
with "Show in bar", which moves that control between the window's bottom
bar and the menu, for all windows. Placement is keyed by the control's
action icon, kept in the page and its localStorage (survives SteamVR
restarts); inBar / inMenu set defaults. floatInTheater gives theater
windows the Float control back.
The popup is a scene-graph panel of its own, attached to the pressed
button's (or the menu's) anchor like SteamVR's tooltips and menu, so the
bar and menu panels don't change; the menu's focus auto-close is held back
while its popup is open. Coordinates with window-curvature through its
sfui-curv-* contract. Lookups by signature ("frame-controls" in
lib/signatures.json, check-only anchors for the rest).
Without Steam's Developer Mode the "+" menu hides konsole, systemsettings,
dolphin, plasma-discover, vlc and a few more by executable name. The patch
empties only that list's iterator, leaving the setting itself untouched.
steamFrame.dashboard.windowCurvature: the "Toggle Curvature" row of a
window's More Options menu becomes a control (click: curved -> flat,
flat -> stock; drag up/down with the laser: curvature relative to
SteamVR's stock curve, snapping to 0 and 1). The patch moves each frame's
curvature-origin node to stock distance / value in outgoing scene graphs;
per-window values live in the systemui page. Lookups by signature
("window-curvature" in signatures.json, incl. check-only anchors).
Shared method hooks (lib/hooks.js, passed by mkPatch as 4th argument):
one SendMessage wrapper for dashboard-windows (now VERSION 3) and
window-curvature instead of a chain of per-patch wrappers; legacy
wrappers on top are unwound.
steamFrame.dashboard.steamCloseButton.enable (default false) gives the
SteamVR dashboard's main Steam window a close button: it docks the window
back into the dashboard, then switches to the previously active window or,
with none, leaves just the dashboard bar. Bar-only survives dashboard
reopens and patch restarts (state in window.__sfuiSteamCloseState, taken
over from the earlier personal version 4 of this patch); the stock
"no active frame -> show Steam" paths are suppressed while it lasts.
MobX, the dock-location enum and the closing component class are found by
signature; check-only signatures cover the dashboard internals it uses.
launcherMenu.grid = { enable; columns; maxRows; } restyles the "+" menu's
programs section as a grid of tiles (icon, name below): Steam's own items
stay in place, maxRows limits the visible rows, and Steam's scroll fade is
recomputed so it only shows where there is more to scroll. The pinned
Desktop row is slim and centred in tile mode.
launcherMenu.iconFallbacks (default utilities-terminal, preferences-system)
installs hicolor copies of Breeze app icons, since Steam resolves program
icons only in hicolor; Konsole and KDE System Settings had none.
The checker gains checkOnly "stylesheet" signatures (matched against the
bundle's CSS files) to cover the scroll fade's gradient; launcher-menu-grid
signatures cover the section keys and the ScrollFade classes.
dashboard-windows: steamFrame.dashboard.windowMaxScale and
windowDistance.{world,theater,dashboard}.{min,max}, one runtime patch of the
SteamVR dashboard (systemui, 127.0.0.1:8087) that rewrites
frame-resize-scale-max and grab min/max-distance in the scene graph sent to
vrcompositor, then asks for one resend so changes apply immediately.
Registered only when an option is set. The mailbox class and the
scene-graph scheduler are found by signature (mkPatch, "dashboard-windows"
in lib/signatures.json, bundle vrwebui-systemui), so
scripts/check-signatures.mjs checks them offline too.
steamvr-debugger: steamFrame.steamvrDebugger.enable, defaulting to true when
a UI patch uses port 8087; merges VRWebHelper.DebuggerEnabled into
steamvr.vrsettings before every SteamVR start, and reverts it (only if it
set it) when turned off.
Stock, clicking a program in the VR dashboard's "+" menu only calls
SteamClient.Apps.LaunchNonSteamApp; the menu stays open until the
program's window appears, so users click again and launch it twice.
New launch/ patch (SharedJSContext) wraps LaunchNonSteamApp, whose only
caller is this menu: closeOnLaunch closes the menu through the "+" bar
button's own popup handle right after a launch; launchDebounce ignores
repeated launches of the same command line within N seconds (logged to
the steam-ui-patches journal). Both opt-in, like the other launcherMenu
options.
steamFrame.uiPatches.patches registers JS patches that the
steam-ui-patches user service keeps injected into Steam's (or SteamVR's)
web UI over the local CEF DevTools ports and reverts when it stops.
steamFrame.launcherMenu uses it for the VR "+" menu: sort = true sorts
the programs by name; pinDesktop = "top" / "bottom" pins Desktop above or
below the scrolling list.
install.sh installs Nix (nix-installer, steam-deck planner, flakes
enabled) and activates a Home Manager configuration, creating one from
the new flake template if there is none; uninstall stops Home Manager's
user services, runs home-manager uninstall and removes Nix and per-user
leftovers; status shows the current state. Works piped from curl.
