The gamescope session's emulated display takes its rate from the display, and the frame generation and the frame counter follow the cap and the multiplier. Together with GameNative/gamenative-drm#41 and GameNative/gamescope#26.

At a 40 cap, changing only the multiplier: x2 produces and counts 80 frames a second, x3 120, x4 160, on a 120 Hz or a 60 Hz display alike, and the mode does not move — it changes only when the display does.

What it does

  • applyPanelRefresh reports the display's own rate to the daemon and nothing else; the cap and the multiplier never enter it. The mode nudge (backend_set_dirty, now allowlisted in the injector) is asked for only by the display listener, so a display change reaches a running session and a QuickMenu change moves nothing.
  • applyLsfgMultiplier reports the rate before the LSFG settings, so the config the shim opens the generator from carries the rate in force.

Measured

Retroid Pocket Nova, Hades II, cap 40, one session per display:

display x2 x3 x4 mode
120 Hz 80.0 120.0 160.0 120 Hz throughout, one selecting mode, no nudges
60 Hz 79.8 120.0 160.0 60 Hz throughout, 40.3 acquires/s

Forcing the display 120 → 60 mid-session reported 60 and re-selected the mode once, which is the display-change path. The reverse could not be forced on this device (SurfaceFlinger kept the panel at 60 until the session ended), so that direction is unverified rather than verified-working.

Files

  • ui/screen/xserver/XServerScreen.kt — applyPanelRefresh, the change-only nudge, the rate applied before the LSFG settings.
  • display/GamescopeConVar.kt — BACKEND_SET_DIRTY.
  • display/GamescopeCommandQueue.kt — nudgeDisplayMode().
  • display/GamescopePayload.kt — payload 20261101.1.
  • jniLibs/arm64-v8a/libgamenative_drm.so — rebuilt (aa33a6a4) from gamenative-drm#41.

The branch's earlier commits describe two intermediate designs this one replaces (the mode following the cap, then the produced rate); the final state is what the diff shows.


Summary by cubic

The gamescope session now advertises the display's own rate as the emulated mode, so the frame-rate cap and generation multiplier affect only frame production and counting, never the mode. The mode changes when the display does, and a mode nudge is issued only on a display change.

  • applyPanelRefresh reports the display rate alone and nudges the mode only when that rate changes after the first report.
  • applyLsfgMultiplier applies the rate before the LSFG settings so the generator opens with the rate in force.
  • Payload bumps to 20261101.6, replacing 20261101.5's Xwayland (which never signaled ready because it lacked the unversioned-libxcvt fix) with one linked against the payload's libxcvt.so; the rebuilt libgamenative_drm.so no longer halves the source rate on slow panels.

Summary by CodeRabbit

  • Bug Fixes
    • Gamescope sessions now report the active display refresh rate and update the display mode when that rate changes.
    • FPS cap and LSFG changes no longer affect the reported display mode refresh rate.
    • LSFG updates apply the FPS limit before LSFG settings. X11 sessions and invalid refresh rates are unaffected.
  • Updates
    • Updated the Gamescope runtime.

…erwise

The daemon reports the panel's own rate as the session's emulated mode. That is
right for everything at or above the panel — the cap is enforced at acquire, so
the compositor's grid should stay at the rate the display can latch. Below the
panel it is not: a 30 cap on a 120 Hz panel had the connector advertise 120, the
compositor paint at 120 and the divisor base be 120, so the session ran a display
three times the rate it was asked to produce.

`applyPanelRefreshForCap` decides one number per apply: the cap when it is below
the panel, the panel otherwise, and it is called from the gamescope arm of the
limiter whenever a target changes. `refreshFpsLimit` passes the current cap too,
so a display change (and session start, which already sets the rate before
`nativeStart`) re-evaluates rather than re-reporting the panel blindly. X11
sessions are untouched: they pace through the renderer and the present extension,
not through the emulated display.

The jniLibs daemon is rebuilt from gamenative-drm `5ecab43`, which is the code
this behaviour needs: the mode is the panel's rate, the frame ring counts what
was produced, and a scan-out subscription now outlives the allocator role in both
directions.
The connector advertises the rate the session is asked to produce — the cap times
the frame-generation multiplier, clamped to the panel — and gamescope has to take
it mid-session: at a 40 cap, x2 must run an 80 Hz mode and show 80 fps, x3 120
and 120, x4 120 and 160, on the QuickMenu's change alone.

`applyPanelRefreshForCap` derives that rate from the multiplier as well as the
cap, reads the multiplier from the container rather than `isLsfgAvailable` (that
is a composition-time value, and the QuickMenu's switch changes the container
without recomposing this screen), reports it, and asks gamescope to re-read the
connector when it changes — only then, because a nudge forces a modeset.
`applyLsfgMultiplier` reports the rate before the LSFG settings, so the config
the shim opens the generator from carries the rate in force instead of the one
from before the change.

- `display/GamescopeConVar.kt`: `BACKEND_SET_DIRTY`, gamescope's own re-poll.
- `display/GamescopeCommandQueue.kt`: `nudgeDisplayMode()`, a one-shot action.
- `ui/screen/xserver/XServerScreen.kt`: the produced rate in
  `applyPanelRefreshForCap`, the change-only nudge, the multiplier documented,
  and the rate applied before the LSFG settings.
- `display/GamescopePayload.kt`: payload 20261031.6.
- `jniLibs/arm64-v8a/libgamenative_drm.so`: rebuilt from the daemon commit that
  serves the rate live (`69f03ef6`).

Measured on the Retroid Pocket Nova (120 Hz panel), Hades II, one session, cap
40, changing only the multiplier: 80 Hz mode / 80.2 fps at x2, 120 / 120.0 at
x3, 120 / 160.0 at x4, back to 80 / 80.0 at x2.
`applyPanelRefresh` reports the display's own rate and nothing else. The cap and the
frame-generation multiplier never enter it: the mode is what the compositor runs at, so it
changes when the display changes and at no other time. At a 40 cap the mode stays at the
panel's rate while x2 produces 80 frames a second, x3 120 and x4 160, which is what the frame
counter reports.

The mode nudge stays, and is now asked for only by the display listener: a display change
reaches the running session through it (gamescope re-reads the connector and re-selects the
mode), while a QuickMenu change moves nothing. The first report does not nudge — it is the rate
the session starts on anyway.

- `ui/screen/xserver/XServerScreen.kt`: `applyPanelRefreshForCap` becomes `applyPanelRefresh`,
  reports the display's rate, and nudges only on a change after the first report.
- `display/GamescopePayload.kt`: payload 20261031.7, whose shim no longer halves the source
  rate on a slow panel.
- `jniLibs/arm64-v8a/libgamenative_drm.so`: rebuilt (`aa33a6a4`).

Measured on the Retroid Pocket Nova, Hades II, cap 40, one session per display: 120 Hz display
80.0 / 120.0 / 160.0 at x2 / x3 / x4 with a single `selecting mode 1280x960@120Hz` and no
nudges; 60 Hz display 160.0 at x4, 120.0 at x3, 79.8 at x2 with 40.3 acquires a second;
forcing the display to 60 Hz mid-session re-selected the mode once.
… cap

The payload carries the gamescope build with the A52 vblank time-grid limiter
patch disabled (GameNative/gamescope#26) and the shim built from the daemon
change in GameNative/gamenative-drm#41, where `source_cap` is the user's cap as
asked: the display no longer halves it on a slow panel, and generation runs at
`multiplier - 1` frames per source frame whatever the mode.

`GamescopePayload.VERSION` must name the archive that ships with the build, so
it moves with it.

Walkthrough

The change adds a Gamescope backend action that requests a connector re-read and mode selection. XServerScreen reports eligible panel refresh rates and nudges mode selection when a reported rate changes. LSFG multiplier updates apply the FPS limit before LSFG settings.

Refresh the mode after moving the game to another display.

When an external display is connected or removed, ExternalDisplaySwapController reparents the game view, but this listener ignores both events. A move from a 120 Hz panel to a 60 Hz display can therefore leave Gamescope at 120 Hz until another refresh event or limiter change. Call refreshFpsLimit after the view attaches to the new display.

Preserve the baseline across activity recreation.

If the panel rate changes while the activity is being recreated, remember resets advertisedPanelHz to zero. The first report then skips the nudge, although the Gamescope session can survive that recreation. The old mode remains until another rate change. Keep the baseline with the session, and reset it when the session ends. (raw.githubusercontent.com)

Minor · Functional Correctness · Quick win

Do not mark the panel rate as applied before the dirty action succeeds.

backend_set_dirty can execute during an applicable session or during the deferred resume apply. When nativeGamescopeCommand rejects or fails, GamescopeCommandQueue only logs the result and discards the action. applyPanelRefresh still advances advertisedPanelHz, so later reports of the same rate do not retry the nudge. The mode can remain stale.

Handle the failure at GamescopeCommandQueue: retain or retry the one-shot action, and expose its eventual success before XServerScreen suppresses another nudge.

Minor · Report the destination display for both swap directions. · XServerScreen.kt:843-845

app/src/main/java/app/gamenative/ui/screen/xserver/XServerScreen.kt:843-845
Minor · Functional Correctness · Quick win

Report the destination display for both swap directions.

The swap callback reports only gameOnExternal, and the current callback does not refresh the panel rate. A return to the internal display can therefore leave the daemon using the external display's rate. Pass the destination Display for both transitions and refresh with that explicit display.

…yland shared-memory attach

Payload = shipped 20261031.3 + bin/gamescope and bin/Xwayland from the
gamescope gamenative CI (A52 disabled, #26; Xwayland from GameNative/xserver
gamenative with #1 + #2) + lib/libadrenotools_gamescope.so from
gamenative-drm master (#41 + #42). Daemon in jniLibs from the same master.

Updated to payload 20261101.5, built from the merged branches:

  • bin/gamescope from GameNative/gamescope gamenative (907a20c, #26 merged; CI run 41325056072), sha256 65d024fc…
  • bin/Xwayland from GameNative/xserver gamenative (Drm checks #1 + Implemented replacement of steam_api.dll with Goldberg's to allow acc… #2 merged, built in the same CI run), sha256 8d843cca…
  • lib/libadrenotools_gamescope.so from gamenative-drm master (efd50ab, #41 with #42), sha256 fb906dbc…
  • everything else byte-identical to the shipped 20261031.3

Equivalent stack (20261101.4 built from the PR branches) verified on the RP6 (SteamWorld Dig 2: HUD 59.9, 0 tears / 1799 frames during play) and the Odin 3 (Dead Cells: HUD 60.0, 59.1 fps, 0 tears / 1499 frames).

…ibxcvt.so

20261101.5's Xwayland was built by the gamenative workflow without the
unversioned-libxcvt fix, so it needed libxcvt.so.0 and never loaded
("Xwayland server 0 did not signal ready"). 20261101.6 is the same
payload with the Xwayland built from the identical xserver source
(bd9c2cdd4 = merged gamenative) on the fixed workflow.

Payload 20261101.5 is broken, replaced by 20261101.6. Its Xwayland was built by the gamenative workflow, which lacks the unversioned-libxcvt fix, so the binary needs libxcvt.so.0 while the payload ships libxcvt.so; Xwayland never loads and gamescope reports "Xwayland server 0 ('') did not signal ready within 15000 ms".

20261101.6 = same gamescope (65d024fc…) and shim (fb906dbc…), with the Xwayland built from the identical xserver source (merged gamenative = bd9c2cdd4, verified with git diff) on the fixed workflow (4dded856…, links libxcvt.so). Archive 14291543 B, sha256 c7bb0d4d7d274b8279cbeb6d8417c696c47fb59ec3288f68e772507b13c04bbd, uploaded and verified. The .5 archive is being removed from the CDN. Workflow fix for future builds: GameNative/gamescope#27.
