niri: retire flameshot binds, absolute script paths in spawn-sh
Live census 2026-10-14: every flameshot mode on this box captures via xdg-desktop-portal-gnome → niri's single-output API (niri#4313) — full AND screen hang ~15 s and error docked (verified: exit 124, no file). Replace all six flameshot binds with niri-native equivalents: all-monitors script (Print/Ctrl+Shift+1/Mod+Shift+S), screenshot-screen (Alt+Print/Ctrl+Shift+2), interactive screenshot UI (Ctrl+Print/ Ctrl+Shift+3). Absolute script paths everywhere: niri's spawn-sh PATH is system-only, ~/.local/bin absent — the bare screenshot-desk.sh and desk.sh binds were silently dead. bats 27/27.

# Screenshot Matrix
|
||||
|
||||
Three capture stacks coexist on blankpad: **flameshot** (portal → niri
|
||||
D-Bus screenshot API), niri's built-in **screenshot UI**, and
|
||||
**scripts/screenshot-desk.sh** (drives niri per-output actions). The
|
||||
flameshot full-screen path breaks the moment the laptop docks to a
|
||||
second output.
|
||||
**Flameshot is retired on this box (2026-10-14).** Every flameshot mode
|
||||
on Wayland captures through xdg-desktop-portal →
|
||||
`xdg-desktop-portal-gnome` → niri's GNOME-Screenshot compatibility API,
|
||||
which is hard-limited to one output. All binds are niri-native now.

||||

||||

|

`Mod+Shift+S` used to open noctalia settings; noctalia settings moved to

**`Mod+Shift+O`**.

Noctalia settings lives on `Mod+Shift+O` (moved off Mod+Shift+S).
|
||||
|
||||
## Why `flameshot full` dies docked
|
||||
## Why flameshot died (and not just `full`)
|
||||
|
||||
- Flameshot 14 full-screen capture → xdg-desktop-portal →
|
||||
`xdg-desktop-portal-gnome` → niri's GNOME-Screenshot compatibility D-Bus
|
||||
service.
|
||||
- That service calls `Niri::screenshot_all_outputs` (src/niri.rs), which
|
||||
starts with `ensure!(outputs.len() == 1)` (FIXME: multi-scale/crop
|
||||
unsupported). On a 2-output virtual screen the request is refused;
|
||||
flameshot pops an error bubble after the portal round-trip — the
|
||||
"bunch of errors after a delay".
|
||||
- Compositor-side fingerprint (`journalctl --user -u niri`):
|
||||
`WARN niri::niri: error taking a screenshot: Condition failed: outputs.len() == 1 (2 vs 1)`
|
||||
- Portal chain: flameshot 14 → `xdg-desktop-portal-gnome` → niri D-Bus
|
||||
API → `screenshot_all_outputs` → `ensure!(outputs.len() == 1)`
|
||||
(FIXME upstream).
|
||||
- `flameshot full` on 2 outputs: each press emits **3 refusals**
|
||||
(composited screen + per-output) — `WARN niri::niri: error taking a
|
||||
screenshot: Condition failed: outputs.len() == 1 (2 vs 1)` in
|
||||
`journalctl --user -u niri`; bubbles arrive after the portal
|
||||
round-trip ("bunch of errors after a delay").
|
||||
- `flameshot screen` is NOT exempt: live test docked, 2026-10-14 —
|
||||
`flameshot full` and `flameshot screen` both hang ~15 s, exit 124
|
||||
under timeout, **no file written**.
|
||||
- Upstream: [niri#4313](https://github.com/niri-wm/niri/issues/4313)
|
||||
(identical stack: niri 26.04 + Flameshot 14 + portal-gnome; closed as
|
||||
duplicate, unfixed in 26.04/8ed0da4).
|
||||
|
||||
## Why not niri's built-in `screenshot` UI
|
||||
|
||||
niri 26.04's default `screenshot` action opens the interactive
|
||||
screenshot UI, and its selection is single-output by design
|
||||
("this implementation allows only single-output selections for now",
|
||||
src/ui/screenshot_ui.rs). One press = one monitor.
|
||||
(closed duplicate, unfixed in 26.04/8ed0da4),
|
||||
[flameshot#4449](https://github.com/flameshot-org/flameshot/issues/4449).
|
||||
- Portable desk (1 output): flameshot would work again — that is the
|
||||
portal's only supported shape.
|
||||
|
||||
## The all-monitor path: `scripts/screenshot-desk.sh`
|
||||
|
||||
- Bind: `Mod+Shift+S` in [[keybindings|keybindings.md]].
|
||||
- Deploy form: symlink `~/.local/bin/screenshot-desk.sh` →
|
||||
`~/.omp/scripts/screenshot-desk.sh` (same convention as `desk.sh`).
|
||||
- Algorithm: for each active output from `niri msg --json outputs`,
|
||||
`focus-monitor` → `screenshot-screen --path` (absolute, one PNG),
|
||||
then restore the previously focused monitor. All niri-native, no
|
||||
grim, no portal.
|
||||
- Files: `~/Pictures/Screenshots/Screenshot from
|
||||
YYYY-MM-DD HH-MM-SS <connector>.png` (dir overridable via
|
||||
`SCREENSHOT_DIR`). Also honors `screenshot-path` in misc.kdl for the
|
||||
UI/screenshot-screen default when no `--path` is passed.
|
||||
- Verified 2026-10-14 docked: two valid PNGs (eDP-1, DP-2), focus
|
||||
restored.
|
||||
- Per active output (`niri msg --json outputs`): `focus-monitor` →
|
||||
`screenshot-screen --path` (absolute) → restore prior focus.
|
||||
- All niri-native; no grim, no portal. `SCREENSHOT_DIR` overrides the
|
||||
output dir.
|
||||
|
||||
## The spawn-sh PATH trap (why "it works in the shell" lies)
|
||||
|
||||
niri's environment `PATH` is the **system** path — `~/.local/bin` is
|
||||
**absent** (`tr '\0' '\n' < /proc/$(pidof niri | awk '{print $1}')/environ`).
|
||||
`spawn-sh "some-user-script"` fails silently. Rules:
|
||||
|
||||
- Keybinds use **absolute** script paths
|
||||
(`/home/blank/.omp/scripts/…`). Applies to `desk.sh` too — its bare
|
||||
bind was dead for the same reason.
|
||||
- A bare script name in a keybind is a bug on this box.
|
||||
|
||||
## Census commands
|
||||
|
||||
```bash
|
||||
niri msg outputs # how many outputs live
|
||||
journalctl --user -u niri --since today | grep -i screenshot # portal-path failures
|
||||
pgrep -a flameshot # daemon state
|
||||
journalctl --user -u niri --since today | grep -i screenshot # WARN vs DEBUG saves
|
||||
tr '\0' '\n' < /proc/$(pgrep -x niri | head -1)/environ | grep ^PATH # spawn-sh environment
|
||||
```
