The gamepad-cursor port queried the X pointer on every vblank, a
blocking round trip to Xwayland on the paint thread. With no cursor
image the position comes from wlserver as upstream; while the cursor is
hidden for inactivity X is asked every 50 ms. The realtime-queue comment
now says it is a no-op on KGSL Turnip.
The session's watchers slept with sleep(1) and read files with cat, an
exec each under proot; they now wait in bash itself. steam-compat
writes its tool, the adopted wrappers and config.vdf only when they
change, the games watcher probes ownership when its matches change or
every five minutes instead of every 30 s, and Proton no longer inherits
the client's steamrtarm64 library path.
fake_id0 (loaded by -i for Xwayland's set*id) now traces only the set*id
family and the xattr fixups when the ids given are proot's own, and the
seccomp filter traces ioctl only for the termios and FICLONE requests
proot rewrites. The faccessat2 and statx exit stops are dropped on
kernels that have the calls.

A local build was signed with the testkey alone, which a release refuses
as an update ("signatures do not match"): testing on a device with a CI
build meant uninstalling it and losing its data first.
With an untracked .signing.env (RELEASE_KEYSTORE, RELEASE_STORE_PASSWORD,
RELEASE_KEY_ALIAS) in the checkout, or in the main checkout for a
worktree, build_local.sh finishes with tools/release/sign-apk.sh as CI's
main builds do, and the apk installs over a release. Without the file
nothing changes. DROIDDECK_SIGNING_ENV points at the file explicitly.
The desktop forced a software cursor (WLR_NO_HARDWARE_CURSORS=1) because
labwc's cursor never showed when handed to the app's compositor. With a
software cursor wlroots never scans out: every frame of a full-screen game
was composited by labwc first ("Direct scan-out disabled by software
cursor", 2284 times in one Adreno 825 report).
Why the cursor never showed: wlroots' Wayland backend attaches and commits
its cursor surface before wl_pointer.set_cursor gives it the cursor role,
and sets it again with nothing new committed each time the pointer enters.
The compositor released a role-less surface's buffer on commit, so the
cursor surface had no image by the time it became the cursor.
- A role-less surface's last buffer (cursor-sized only) is held until the
next commit; set_cursor publishes it, and a repeat set_cursor of the
surface already shown unhides its last image.
- A dma-buf cursor is read back after the client's implicit render fence,
as the zero-copy path waits for it.
- The desktop no longer forces a software cursor.
Device-tested on the AYN Thor (Adreno 740, 1920x1080): labwc's own cursor
is drawn, with its shapes (I-beam over a terminal); wlroots logs "Direct
scan-out enabled" for a full-screen glxgears. At the same 60 fps on screen
the GPU is 3.0 % busy against 4.6 % with the software cursor, both at
550 MHz.
mangoapp's VRAM figure on a Qualcomm driver comes only from the gpu_mem_total
trace event. The tracefs stand-in's event list now declares that event as
Android kernels do, and reading the stand-in's events answers with one
record carrying the total KGSL reports in /sys/class/kgsl/kgsl/page_alloc,
which every Adreno under Android has and the app can read.
Three things kept Valve's mangoapp from drawing the overlay in a session:
- GLFW 3.4 takes XDG_SESSION_TYPE=wayland with WAYLAND_DISPLAY set as
Wayland-only, and mangoapp needs gamescope's X server; the wrapper sets
XDG_SESSION_TYPE=x11.
- On a Qualcomm display driver it opens a tracefs instance for the GPU memory
total and aborts when that fails, which it always does for an Android app.
The session preload now places the instance in an empty directory of its own
when the real one cannot be made.
- gamescope sends it each frame's timings through a System V message queue,
and Android kernels have no System V IPC. sysv.c now emulates the queue
operations gamescope and mangoapp use, beside its semaphores and shared
memory.
The Quick Access menu's performance overlay toggle and level slider stayed
greyed out: the client exposes SteamClient.System.Perf only with -steamos3,
which SteamOS and Armada pass alongside -steamdeck. Deck mode now launches the
client with both. The session already puts package/beta back to the forced
branch before every start, which keeps -steamos3's own branch switch from
turning into an update loop.
The Deck mode switch moves from the Performance page to the Steam page's
Client settings, next to the client branch it selects by default.
* docs(release): draft 0.2.0 beta notes
* docs(release): credit prs and authors in 0.2.0 notes
* docs(release): add #39 and #45 to 0.2.0 notes
* chore: update readme
* fix(ui): cover the whole screen with the capsule wall
The wall was shifted right and then tilted around its own centre, which
left the bottom-left of the home and loading screens bare. Centre it and
size it to the tilted page's bounding box so every corner stays covered.
* feat(ui): flood from the play button into the throbber
Starting a session from a blue button no longer slides the session up
over the front end. The button stretches out on staggered springs until
the page is the ball's blue, the session opens on that same blue with no
window animation, and the blue gathers into the throbber's ball before
the throbber starts. Re-joining a running session, tiles and reduced
motion keep the old rise.
* docs(release): cover everything since 0.1 in the 0.2.0 notes
0.2.0 is the first release from the org, so list what DroidDeck does
as a whole, grouped by area: org pull requests as #N, pull requests
from before the move as The412Banner/DroidDeck#N, and the early work
that predates pull requests by author. CI and build work gets one
short section instead of a line each.
* docs(release): add screenshots and animations to the 0.2.0 notes
Lead with a game running and a few visual highlights, fold the full
list into collapsible sections by area, and shorten every line to the
feature and its credit. Pre-move pull requests read as legacy#N.
* fix(session): give the desktop its own loading hints
The loading screen's hints were written for Steam, so starting the
desktop or an emulator said the first run downloads Steam and that
leaving the app pauses Steam. Desktop and program sessions now rotate
through hints about the desktop instead.
* fix(build): skip incomplete NDKs when picking one locally
An interrupted sdkmanager install leaves a directory like
28.2.13676358.failed under ndk/, which sorted last and was picked
without a toolchain in it. Only consider directories that carry
source.properties.
* docs(release): show launching straight into Big Picture
* docs(release): credit the launch transition to #46
Twice today a session's Xwayland aborted from one thread ("The futex
facility returned an unexpected error code"), proot lost the tracee, and
the process lived on reparented to init: proot's seccomp filter, with no
tracer left, answers ENOSYS, so Xwayland's main loop logged
"WaitForSomething(): poll: Function not implemented" until something killed
it - 9 GB after Dolphin, 13 GB after PPSSPP. --kill-on-exit and the tree
sweep only reach what proot still traces, and the straggler sweep ran only
at the next session's start.
Now a session stop also kills every process of ours whose executable lives
in the Linux runtime, and bannerlator-session keeps only the first
BL_LOG_CAP bytes (256 MB) of session.log, draining the rest so a writer
that filled it is not killed by SIGPIPE.
Cemu never showed a frame on DroidDeck: its Getting Started dialog blocked
every first launch (the folder picker cannot reach ROMs), the session's
controller helper aborted it, and the desktop's Vulkan renderer drew no
cursor. With the Turnip KGSL fix in the driver and the haptic-optional
Cemu in the catalog, this makes the app side complete:
- bannerlator-pad-defaults seeds Cemu's settings.xml once: the Wii U games
folder, Vulkan, and Cubeb audio on the default device for both the TV
and the GamePad speaker at full volume (Wipeout 3 plays through the
GamePad; Cemu's own default is 20 %).
- The Cemu tile launches full screen (-f).
- libfakeinput.so is preloaded into every session process and exported its
static C++ runtime (~7000 symbols); programs unwound through it and
aborted (shadPS4 in pthread_exit, Cemu's controller thread). Link with
--exclude-libs,ALL, and fail the build if the runtime leaks out again.
- On the Vulkan and GLES desktops the pointer worked but no cursor was
drawn: wlroots hands the cursor to the app's compositor, which draws
none. WLR_NO_HARDWARE_CURSORS=1 makes labwc composite it itself.
Device-tested on the FIT: Super Mario 3D World in-game at 35-37 fps with
sound, Deus Ex HR DC and Wipeout 3 launch with sound; RPCS3, Dolphin and a
Steam session (FlatOut) unchanged on the same driver.
Brings the proot patch set up to WinNative 53836ca9 on top of the #772 port:
- trace prctl, setrlimit and prlimit64 in the seccomp filter only for the
arguments proot acts on, and uname only where the core rewrites it
- answer a seccomp stop's filter flags from the registers fetched for its
translation, reuse those registers, and skip the sysexit stop of wait4 left
to the kernel and accept without a sockaddr; the flags come from proot's list
merged with the enabled extensions, and a syscall an extension replaced
keeps its exit stop
- take a clone3 child's flags and exit signal from struct clone_args
- name a thread's /proc/self by its thread group and resolve /proc/thread-self
- translate fchmodat2, send openat2 callers to openat, and bound sysnum lookups
by the table length
- sweep relatives only for tracees that have children or ptracees, and empty
the per-stop memory collector instead of reallocating it
The session's proot runs with -i <app uid>, and the rootfs names that uid
root, so the client calls itself root while geteuid() returns the app's
uid. The read-only retry required geteuid() == 0 and never ran: the
Proton Experimental (ARM64) update still failed with Missing file
permissions on wineopenxr.dll (2026-09-26 16:07, 2,471 read-only files).
Also recognise the client by the path it was started by: the kernel's
/proc/self/exe names proot's loader for every process in the session.
The client runs as proot's root, which the kernel does not see, and
leaves many content files read-only; an update that rewrites one was
refused (EACCES) and cancelled with "Missing file permissions"
(Proton Experimental (ARM64), wineopenxr.dll). For the client's own
processes, a refused write-open of a file the app owns now gets the
owner's write bit - on the file, or on the directory a new file goes
into - and one more try. Games and Wine keep ordinary permissions.
With Steam publicbeta 1790380355 the client spent 27 s in its post-logon
compat phase and dropped the install request the session sent 15 s after
sign-in, so a clean install never offered Proton Experimental (ARM64).
Wait for the console log's "Waiting for compat in post-logon took" (90 s
at most), then ask, up to three times a minute apart until the install
starts.
With the check reached from the client's own runs right after login, the Steam client segfaulted
within seconds, four sessions out of four; the same build without the check (test/bisect-no-launch-check)
and the last build before it both reach Big Picture. Now every run that is not a game launch -
the client's probes, app id 0 - is left exactly as before. Each check logs one line.
Steam runs its graphics probe through every registered Proton at once after login, all in
compatdata/0. Prefix system32 links point into the Proton that set it up last, and the other
Protons' Wines, running outside Proton's pfx.lock, wrote their builtin DLLs through them into that
Proton's tree (device: GE's FEX DLLs became Proton Experimental's at session start).
- bannerlator-steam-compat: both wrappers (Valve's depot launcher and the third-party
bannerlator-proton-wrap) give a tool-0 run STEAM_COMPAT_DATA_PATH=.../compatdata/0-<tool>, and
before every other launch check the Proton's files against the app's desired.tsv and put back
anything that differs (same Proton build only), logging to reapplied.log.
- ComponentsManager writes desired.tsv plus unpacked copies of the packages in use into the
runtime after every change; the page and the drawer show 're-applied at launch'.
In touchpad mode the cursor moved but Big Picture highlighted nothing and a tap-to-click
selected nothing: the nested pointer's motion reaches wlserver as touch 0, and in Passthrough
(the touch mode Big Picture sets) a motion for a touch that is not down moves nothing, so the X
pointer stayed where it was. 0111 passes bAlwaysWarpCursor, as the other touch modes already warp.
3.16.29's Wayland backend bound only wl_pointer and wl_keyboard; touch from DroidDeck's
compositor was never read, so Steam could not be touched. 0110 binds wl_touch in the input
thread and feeds each finger to wlserver_touchdown/touchmotion/touchup, the Steam Deck
touchscreen's path, so Big Picture's Passthrough touch mode gets real touches.
Tried on device: with a session bus the client still sat on "Switching to Desktop..." and
never reached its legacy path (no "No SteamOSManager support" line, steamos-session-select not
called), so the bus was not what it waited on. Sign-in was unaffected.
This reverts commit 40fc5463f3.
Big Picture's Switch to Desktop asks SteamOS Manager over the session bus before falling back to
steamos-session-select (steamui.so). The Steam session had no session bus, the ask never
finished, and the client sat on "Switching to Desktop..."; the new stub was never called. A
bus with nothing on it answers at once, and the client takes its legacy path.
- The front end's "Steam Desktop UI" started a Steam session without -gamepadui, and the client
put itself into Big Picture under gamescope anyway. It now opens the desktop with Steam's
desktop client started in it (BL_DESKTOP_STEAM, the desktop's autostart, the same
bannerlator-steam-launch the menu's Steam entry uses).
- Big Picture's power menu "Switch to Desktop" runs steamos-session-select, which did not exist,
so it sat on "Switching to Desktop..." for ever. The new stub leaves the app a request
(session=desktop in the steam-launch file); the app ends the Steam session and starts the
desktop with Steam's desktop client open.
AutoPlace on its own left the resized window in the top-left corner; with policy="center" it
opens in the middle of the desktop. Tried in a running desktop (labwc --reconfigure).
melonDS remembers a 1x window for the front end's full-screen toggle, too small on a desktop.
A labwc window rule (only the desktop reads rc.xml) resizes it to 800x600 on open and places
it again by the desktop's centre policy.
The desktop set QT_QPA_PLATFORM=wayland for every program. The melonDS AppImage bundles only
Qt's xcb plugin, so from the desktop it exited at once: "Could not find the Qt platform plugin
wayland ... Available platform plugins are: xcb" (exit 127). "wayland;xcb" keeps LXQt on
Wayland and lets such an AppImage use Xwayland. Proven in a running desktop: labwc mapped
"melonDS 1.1".
The guide button's toggle returns to melonDS's saved window size. A 512x288 window (1x wide,
16:9) is stretched by gamescope to fill the panel, menu bar and cursor with it; at 2x and up
the menus stay at their real size, tiny on a handheld. Written once, with the layout.
