Through the ISP (no colour module), the near-black exposures come out
all zeros, identical every time, so their dequeues change no buffer and
ft-camd never finished learning the side cameras' buffers ("can't tell
which buffers are this camera's yet"): the side pair published nothing.
Such an index is now left unmapped and its frames counted as dark.

(cherry picked from commit 89ec1608d9)
Without the Arcturus module, XRService runs the side cameras through the
ISP ("ISP enabled for tracking cameras (main VFE available)"): NV12 on
vfe0 and vfe1, pitch 1152. ft-camd published only grey cameras, so it
dropped them, and the recorder stopped at "ft-camd publishes only 2 of 4
mono cameras" whatever was restarted.
- ft-camd reads a tracking camera's NV12 luma as its grey image.
- ft-hands and check_sides name the cameras by XRService's numbering in
its log (TrackingCameraInit index 0-3), not by capture pipe, which
moves with the module; a camera whose size isn't its calibration's is
left out. sides.json says which device each camera was.
- camcheck reports the camera map, the ISP routing and which cameras
ft-camd is missing; the recorder says so instead of "restart it",
restarts its own ft-camd once when that's the only problem, and keeps
the map in session.json.

(cherry picked from commit 4db5266cf7)
uninstall.sh replaces the README's thirteen uninstall commands. Run from a
Frametop desktop, those commands stopped the input relay second, which took
the keyboard and mouse away before the rest could be typed. And deleting
~/frametop first left Launch a program -> Desktop pointing at a missing
script.
The script works in two steps. Step 1 stops Frametop from starting: the
launcher entry, the user services (disabled, not stopped), the SteamVR
driver, the menu entries, and the eye grabber and Bluetooth fixes under
/etc (one sudo). Everything running keeps running until the headset
restarts, and the script offers to restart it. Step 2 runs once none of
Frametop's programs run. It deletes the code, and asks before deleting the
settings, recordings, and the dev container.
It doesn't use the rest of the repo, so the Pages one-liner works even when
~/frametop is gone. --dry-run shows each command without running it.

A gaze problem couldn't be told from a report: it had no gaze section. A user's report of
2026-10-05 showed only that the gaze service ran and our tracker was picked.
The report now has a Gaze section: whether the gaze service and our tracker's frame grabber
are enabled and running, when SteamVR's correction and our tracker's calibration were made
(or "none"), and the service's status (ft-gazectl status, on one line: the tracker in use,
whether it's awake and why not, checks.problem). Then the last 10 checks and calibration dots
(checks.jsonl: each dot's reply and whether it was taken), the gaze service's last 60 lines
without podman's exec lines, and the frame grabber's last 20. Nothing in them is an eye image.
Tested on this Frame: each section fills in, and the status is one line.

The desktop has its own XDG_CONFIG_HOME (~/.config/frametop), and SteamVR's tools and OpenVR
read their path registry from there. So from a terminal in the desktop:
- pointer/driver/install.sh (install.sh step 4, every reinstall or update from Konsole) wrote
a new registry, ~/.config/frametop/openvr/openvrpaths.vrpath, with only our driver and
"runtime": null, and never registered the driver with SteamVR. That stray file then hid
SteamVR from every OpenVR program started in the desktop.
- scripts/update-check.py (and so doctor.sh and report.sh) reported OpenVR "can't connect to
SteamVR as a background app" (VRInitError_Init_PathRegistryNotFound, or
InstallationNotFound with the stray file) and "vrcmd --overlays lists no overlays". A user's
report of 2026-10-05 showed both, with SteamVR and Frametop's services fine.
- ft-layout's vrcmd calls (the gamescope backend) found no overlays.
They now run with XDG_CONFIG_HOME=~/.config: the driver installer (install, uninstall, probe,
aimhere), update-check.py (for all its checks: nothing there reads the desktop's own config),
report.sh's vrpathreg show, and ft-layout's vrcmd. report.sh doesn't set it for the whole
report, since session/fix-panels.py --check reads the desktop's Plasma config through it.
The driver installer also removes the stray registry (only vrpathreg's, with no runtime), and
update-check.py warns about one. And vrpathreg runs `xdg-open vrmonitor://driverinstalled` to
tell SteamVR's desktop monitor, which the Frame doesn't have: in the desktop that showed "could
not read file vrmonitor://driverinstalled" on every install. A stand-in xdg-open on its PATH
takes it, so install.sh no longer filters the step's output.
Tested in a fake HOME with a copy of SteamVR's registry, a stray one, and the desktop's
XDG_CONFIG_HOME: the new installer removes the stray file, registers the driver in the copy,
and never reaches xdg-open; the old one wrote the stray file, left the copy alone, and ran
xdg-open. update-check.py from that environment: OpenVR and vrcmd ok (the old one fails both);
its stray-registry warning fires on a seeded file. ft-layout's vrcmd: 119 overlays (was 0).

A fresh install that chose our tracker (the installer's default since 12ad93d) could never
calibrate it, so gaze mode never worked. ft-eyes maps pupils to a gaze only once it has a
calibration, so before its first one ft-gaze's "own" source is empty. ft-gazed then never
counted a sample, Checks.can_run() stayed false, and the calibration refused to open: "Not
calibrated, and the calibration can't open: the eye tracker isn't sending", or "the headset is
off or the tracker isn't sending" from Calibrate. This Frame never hit it, because its
calibration came from the gaze probe. Reported 2026-10-05 on SteamOS stable.
- With our tracker in use, running, and uncalibrated ("blind"), SteamVR's tracker seeing an
eye is enough to open the full calibration (ft-eyes answering is what makes calibrated()
False rather than None).
- Each dot stands in for the gaze, so a click takes the CHECK_WINDOW up to it. ft-eyes already
checks, in calib-point, that each pupil was seen in enough frames and held still then, and
its reason for a refused dot shows in the panel's note as before.
- A quick or five-dot check is refused until then ("use Calibrate"): ours can't take a click
without a calibration.
- With no eyes seen, the reason given is that, not "the eye tracker isn't sending".
gaze/test/first-calibration-test.py runs the service against a fake ft-gaze, ft-eyes and
pointer helper, in a temp HOME: the calibration opens by itself when gaze mode comes on, each
click sends ft-eyes the 0.6 s before it, a refused dot's reason reaches the panel, and
calib-fit leaves the tracker calibrated with gaze mode still on. It passes here and fails on
the previous code. gaze/test/idle-test.py still passes. Not yet tested in the headset.

JakeGreen2145's PR plus our fix 6df6f97: the watcher checks its buses
every 5 seconds instead of every second (about 1% of a core), and
design.md says the watcher is the only cleanup when the VR launcher
runs the desktop in steam.service.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Each check starts two gdbus processes (about 5.5 ms of CPU each on the
Frame), so checking once a second cost about 1% of a core for as long as
the desktop ran. On SteamOS 0.3.0 native activation fails, so the watcher
always runs. A registry left behind now goes within 5 seconds instead of 1.
design.md also says where the watcher matters: started from the VR
launcher, the desktop runs in steam.service, which doesn't stop with it,
so keep-apps.sh and the unit's stop don't clean up there.

Pausing, or hiding the screen a button went down on, took the laser off
it mid-click; the pause gesture's second thumbstick click does that.
SteamVR's laser mouse then forgot the button ("Mouse down count is 1 but
states are all false"), no release came, and the catcher kept showing
whenever the pressing laser was off the panels, even while paused. Being
interactive, it kept the VR game's controllers from it until the
desktop restarted (2026-10-04, Beat Saber).
ft-screens now releases a held button when it's paused, when the screen
it went down on is hidden, or, during VR games, when the pressing hand
controller has held nothing for a second. GetControllerState answers
overlay apps only while a game runs; outside games a hold is never cut.

Conflicts with experimental's pause_toggle, steam_menu and command: actions and its

Plasma 6.2.5 keeps a panel on a screen number and never moves one whose
number is past the screen count, so a taskbar saved on a spare output
(#18, lastScreen=8 with three screens) or on a screen a smaller layout
dropped stayed hidden. Before Plasma starts, session/fix-panels.py moves
such a panel and its tray's containment to screen 0 (the primary),
keeping its widgets, unless screen 0 already has a panel on that edge.
doctor.sh checks the panels' screens, and report.sh lists them with the
live outputs and panels.

Add KEY_MUTE as volume key. It will be mapped to KEY_MACRO28 and
use wpctl to toggle the mute of the default audio sink. The toggle of
the mute state will be done once when the key is pressed instead of
continuously toggling it when it is held down.
This allows the mute button on keyboards to work properly.

GetComponentStateForDevicePath with no input source handle fails for
every render model component while a VR game runs (checked 2026-10-03
with a game up: all 21 components of frame_controller_right). TipOffset
then fell back to the controller's pose, which aims 40 degrees above the
Frame controller's laser. In games, pointing at a screen's middle missed
it and pointing below it hit, so the new aim-to-laser only worked from
the bottom; the controls' reveal and pin/roll aim were off the same way.
GetComponentState still answers then, with the same tip.

SteamVR's own floating windows take the laser while a controller points
at them in a game and give it back when it points away. Frametop's
panels didn't: with the controllers left to the game (outside_games, the
default, or dashboard), they couldn't be clicked without the dashboard.
ft-screens now sets MakeOverlaysInteractiveIfVisible on a screen or
floating window while a hand controller's laser pose meets it, its
controls, or its popups (UpdateAim; curved screens hit on their
cylinder), and clears it 0.3 s after the aim leaves a wider margin. A
drag or a held button keeps it on. The keyboard, one overlay, uses
ComputeOverlayIntersection and now follows the mode when a game starts
or ends while it's open. This replaces the reset button's own aim zone.

8 is about 0.2 degrees on a 3.4 m wide 3440-pixel screen 2 m away, so a

Each desktop screen gets a reset button left of its bar (a reticle). It
puts every screen back in its layout around where you are now, like
Meta+Shift+R (ft-layout apply).
In a VR game the screens leave the controllers to the game (the
outside_games and dashboard modes), so a controller couldn't click any
of their controls. Aiming a hand controller at the reset button now sets
MakeOverlaysInteractiveIfVisible on that button's overlay alone, so the
trigger clicks it; the flag clears half a second after the aim leaves a
zone twice as wide, and the game gets the controllers back. The aim
comes from the laser poses ft-screens already reads to show the controls.
The ft-layout spawn is now RunLayout(cmd), shared with the arrange.

When the checklist says no controllers, exported poses.jsonl has left and right
null and feedback lines carry no controller state: controllers left switched on
still get tracked (one wandered 2 m in a real session) and would read as the

left out too, as the images there are.

sets.bin's capture_ns is CLOCK_MONOTONIC_RAW; poses.jsonl and prompts.jsonl are
CLOCK_MONOTONIC. On 2026-10-03 the two were 0.80 s apart during a session and

capture_ns. take.json now samples RAW minus MONOTONIC as each recording part
starts and stops (as ft-hands' raw_minus_mono_ns), so readers can put each

The Upload page is now three numbered steps: choose the export, log in to
Hugging Face, upload. Log in runs hub.py login, huggingface_hub's browser
login (OAuth device code, as hf auth login does): the link opens in the

- ft-screens "spin next|prev|<degrees>": every unpinned screen and
floating window turns together about a vertical axis through your
head (0.3 s, eased), so the next panel on the right or left comes to
straight ahead; the arrangement stays as it is. Taps during a spin
add to it, from where the panels are headed; grabbing a panel or
placing it (ft-layout, ft-floatd) takes it out of the spin
- when a spin settles, the panel in front gets the pointer (recenter),
typing (as after a click), and KWin's active window: its floating
window, or the top window on a screen (ft-floatd "front N", the KWin
script's activate-output). KWin's outputs follow the screens'
new places (ft-layout scale), as after a move
- the input relay: spin_next and spin_prev actions, Meta+Alt+Tab and
Meta+Alt+Shift+Tab by default; Frametop Input Settings lists them.
Not Meta+Tab: that's Cmd+Tab on a Mac reached through a remote
desktop like RustDesk, and the relay would take the Mac's app
switcher. Meta+Alt+Tab (Cmd+Option+Tab) is unused on macOS,
Windows, and KDE
Used on the Frame (SteamOS 0.3.0 build 20260922) with one screen and

The helper now reads SteamVR's list of panels every 20 s instead of every second, so a panel
made in between (a floating window's menu, frametop.float.N.sub.K, or the Frametop keyboard
the first time it opens) couldn't be clicked with the mouse until the next read. ft-screens
now sends "overlay <key>" to @ft_pointer_helper right after it makes one, and the helper adds
it to its list at once (only frametop.* keys). An older helper ignores it.

The calibration panel runs for as long as the gaze service does, hidden nearly all the time,
and it woke 20 to 30 times a second to look at its socket and SteamVR's events: about 0.9% of
a core, the main cost left with gaze idle.
It now waits in poll() on its command socket: up to a second while hidden, and up to 10 ms
while shown, as before (it still drains SteamVR's events each pass, so a quit is acknowledged
within a second while hidden). A command wakes it at once, so "show" draws sooner than
before. With --watch-stdin, its stdin closing wakes it as well, so stopping it doesn't wait.

ft-gaze's loop slept 2 ms, so 500 times a second it read the head pose
(GetDeviceToAbsoluteTrackingPose), checked the eye tracker's counter, and drained SteamVR's
events, for samples that come 90 times a second.
It now sleeps 4 ms. A new sample is printed within 4 ms of appearing, 2 on average (was 1),
and the pose history still has a pose within 2 ms of any sample's time, which keeps the
head-pose error under 0.2 degrees for a head turning 100 degrees a second. Sleeping until
the next sample is due would have thinned the pose history to 11 ms.

The panel-edge test read visible[edgeKey], and when the last panel the cursor touched was
gone from the overlay list, that added it back as hidden. The map then had more entries than
there are handles, which made the 50 ms visibility poll run every frame, and since the last
commit it also counted as a visibility change each time, so unchanged frames were never
reused. The edge test now looks the key up without adding it.

ft-gaze computed and printed all six sources for every sample: about 1.3 KB of JSON a line
with our tracker (practice2), 120 KB a second through podman's stdio relay for ft-gazed to
json.loads 90 times a second. It also read SteamVR's gaze action for every sample outside
games (UpdateActionState and GetEyeTrackingDataRelativeToNow, two calls into vrserver, 180 a
second), though with our tracker ft-gazed only uses own and mmap1.
- ft-gaze takes --sources LIST (action, mmap1, mmap2, left, right, own, and eye for the EYE
object; all by default, so the probe and ft-eyes-session are unchanged), and with
--watch-stdin a line "sources LIST" on stdin switches them. A source left out isn't read
and prints as {"ok":0} ("eye" as null), so every line keeps the same keys. An older
ft-gaze ignores both, and prints everything as before.
- ft-gazed asks for what it reads: own,mmap1 with our tracker; left,right,mmap1 with
SteamVR's eyes; the source plus mmap1 and mmap2 on the older one-source path. While a
check or the calibration runs or waits to open, all of them, since checks record every
source (the calibration fits the action's correction too) and the fit check reads "eye".
It switches as soon as that changes, well inside the check's 0.45 s settle.
- So the action is read only during checks, or with --source action.
On recorded samples, a line with own and mmap1 is about 700 bytes instead of 1,300
(practice2), and one with left, right and mmap1 about 550 instead of 940 (test1).
gaze/test/idle-test.py now checks that ft-gaze starts with every source for a check and is
then switched to those in use, without the action or own; all its checks pass.

The relay sent the helper one "move" per SYN_REPORT, so a 1000 Hz mouse sent 1000 datagrams
a second to a helper whose loop runs every 8 ms, and each one went through a dozen sscanf
and strncmp tests in the helper before reaching the move handler. In a 200 ms test at
1000 Hz, 149 reports now make 45 moves with the same total.
flush() on a report now sends only once 4 ms have passed since the last move; tick() sends
the rest when due, and the select timeout shrinks to match. Buttons and the gaze
keys still flush first, unconditionally, so a click lands where the pointer was. In the
helper, "move" is now tested first in the command dispatch, and its handling is one lambda.
