ft-layout crashed - and so did arranging the screens - whenever the row
setting in the layout preset is above what the screens fill. plan()
builds a grid with cols = ceil(count / rows) columns; when that leaves
fewer full rows than the setting asked for, the extra rows are empty,
and the per-row height max() over an empty row raised
ValueError: max() arg is an empty sequence
at plan, line 300 (flat) and 312 (curved)
The smallest real case is 4 screens with 3 rows: cols = ceil(4/3) = 2,
the first two rows hold all 4 screens, the third row is empty. Both the
flat wall and the curved preset crashed, so apply, plan and the
auto-arrange at desktop start all failed until the row setting was
lowered. The Rows spinner in Frametop Display Settings (main.qml) allows
any row count up to the screen count, and clamping to the screen count
does not prevent this - 3 rows for 4 screens is within that range and
never fits a full grid - so the crash was reachable from the UI as
shipped.
Reproduced by calling plan() directly with 4 screens and 3 rows: both
kinds raised. Also verified the whole placement matrix (counts 1-10,
rows 1-4) places every screen after the fix.
The fix trims rows to the number of rows the screens actually fill,
rows = ceil(count / cols), after cols is computed. The row count is
used again for stacking (gap times rows - 1, the sum of row heights),
so the stacking matches the trimmed grid: no empty row is ever built,
and a rows setting that can't be honoured degrades to the tightest fit
instead of failing.

"""ft-layout: the Frametop screens' sizes and where they float around you.
|
|
|
|
Two desktop backends (BACKEND in ~/.config/frametop.conf):
|
|
screens (default) ft-screens, our own compositor (screens): each screen
|
|
is its own SteamVR panel with its own resolution and size in metres. ft-layout
|
|
places them directly through ft-screens' control socket (@ft_screens).
|
|
gamescope the old path: every screen one size (at most 1920x1080 worth of pixels),
|
|
panels owned by the SteamVR dashboard, so ft-layout floats each one with
|
|
`vrcmd --dock-overlay` and the pointer helper carries it into place.
|
|
|
|
The layout is relative to your head when it's applied: its position and the direction
|
|
you face (yaw only), like a recenter. It lives in ~/.config/frametop-layout.json:
|
|
{"auto": true, arrange when the desktop starts
|
|
"mode": "preset" | "custom",
|
|
"preset": {"kind": "arc" | "flat", "rows": 1, "distance": 2.0, "gap": 0.05, "height": 0},
|
|
"primary": 2, the screen with the taskbar (1-based; default: the biggest)
|
|
"layouts": {"Work": [{"pos": ..., "face": ..., "roll": ..., "metres": ..., "curve": ...,
|
|
"pin": ...}, ...]}, named layouts: each screen's place (SPATIAL)
|
|
"active": "Work", the named layout the custom arrangement came from
|
|
"profiles": {"Work": {"hidden": [3], "windows": [...]}}, what a named layout opens too
|
|
(docs/profiles.md): screens hidden on their own, and the
|
|
apps' windows (ft-floatd's "windows")
|
|
"default_profile": "Work", the profile the desktop starts with (FT_PROFILE overrides)
|
|
"visibility": {"mode": "always", ft-screens: always | dashboard (only with the SteamVR
|
|
"wrist_angle": 60, dashboard open) | gesture (while you look at a controller)
|
|
"gesture_hand": "left", "gesture_angle": 20}, | toggle (hidden until shown);
|
|
wrist_angle: a pinned screen shows while you see its front
|
|
within this many degrees
|
|
"screens": [{"size": [w, h], "metres": 3.6, ft-screens: pixels, and width in VR
|
|
"curve": 0, ft-screens: cylinder radius in metres, 0 = flat
|
|
"pin": {"hand": "left", "rel": [12]}, ft-screens: riding on that controller
|
|
(left | right), or on the headset (head)
|
|
"scale": 1.0, KWin output scale (1.0 = 100%)
|
|
"hidden": true, ft-screens: hidden on its own, whatever the
|
|
visibility mode (ft-layout hide N)
|
|
"pos": [x, y, z], "face": [yaw, pitch], "roll": 0, custom layout
|
|
"rotation": "normal" | "left" | "right"}, ...], gamescope only
|
|
"panel_size": [w, h]} gamescope: last measured panel size
|
|
Custom positions: x right, y up, -z forward from the head, in metres; face = the
|
|
direction you look to see the screen's front straight on, in degrees, relative to your
|
|
heading; roll = the panel turned about its front, counterclockwise as you see it.
|
|
Presets: "arc" hinges the screens edge to edge around you, each turned to face you
|
|
(like monitors on a desk); "flat" puts them on one flat wall facing forward. Screen 1
|
|
is top left, then left to right.
|
|
|
|
Usage (on the Frame host; Frametop Display Settings calls it too):
|
|
ft-layout apply [--wait SECONDS] arrange every screen; --wait is for desktop start:
|
|
wait for the screens, skip if "auto" is off
|
|
ft-layout capture save the current arrangement as the custom layout
|
|
ft-layout save NAME save it as a named layout too, and use that; with the
|
|
desktop's apps and hidden screens, as a profile
|
|
ft-layout use NAME switch to a named layout, arrange the screens in it, and
|
|
open its apps (moving open windows, nothing closed)
|
|
ft-layout start [--wait SECONDS] desktop start: the profile in FT_PROFILE or default_profile,
|
|
or else as apply --wait
|
|
ft-layout open NAME a profile's launcher entry: use it, or start the desktop in it
|
|
ft-layout default NAME|none the profile the desktop starts with
|
|
ft-layout layouts list the named layouts (* = the one in use)
|
|
ft-layout rename OLD NEW | delete NAME
|
|
ft-layout plan print the arrangement as JSON (no VR needed)
|
|
ft-layout scale per-screen scale, positions (as the screens are around
|
|
you), and primary to KWin
|
|
ft-layout screen-args ft-screens' --screen arguments for the session script
|
|
ft-layout remote-view the primary screen's place in the workspace, for the VNC bridge
|
|
ft-layout toggle hide or show all screens (ft-screens)
|
|
ft-layout hide N|all hide a screen on its own (it stays hidden whatever the
|
|
ft-layout show N|all visibility mode or the hotkey say), or show it again
|
|
