调研方向

Start by tracing the Hyprland-managed PortalCaptureShortcut path through CreateSession, the entry points named in the issue. Reproduce with the reported Hyprland shortcut setup and inspect whether session creation is reached or fails silently. Done means the shortcut starts a capture, or a logged error identifies why portal session creation failed.

描述

Environment

  • Fedora, Wayland, Hyprland 0.55.2 with a Lua config
  • T3 Code beta AppImage (desktop entry X-AppImage-Version=0.1.5), installed Nov 13

Steps

  1. Settings → SnapShots: enabled. Under the toggle it says "Finish shortcut setup". "Change shortcut" shows no saved label.
  2. Added to hyprland.lua: hl.bind("CTRL + SHIFT + 2", hl.dsp.global("com.t3tools.T3Code:capture-window")). hyprctl reload reports no config errors.
  3. Pressed Ctrl+Shift+2 (and Ctrl+Shift+1 in an earlier config). Nothing happens.
  4. hyprctl dispatch 'hl.dsp.global("com.t3tools.T3Code:capture-window")' returns ok. The desktop trace shows no desktop.snapShot.prepareCapture span afterward.
  5. busctl --user tree org.freedesktop.portal.Desktop lists only other apps' GTK sessions. T3 has no session.
  6. Settings → "Set up snapshots for Hyprland" → Shortcut step shows "This shortcut is already set up." with Done/Cancel. The config is unchanged, and T3 still has no portal session.

Expected: after setup, the Hyprland dispatch starts a capture.
Actual: no portal session, no capture, no error in the trace, xdg-desktop-portal or xdg-desktop-portal-hyprland logs.

Notes

  • The Settings default is "Shift + Shift" (both-shift-keys). On Hyprland the app ignores it and uses a hardcoded portal trigger of Ctrl+Shift+2.
  • The desktop trace shows 127.0.0.1:3773/.well-known/t3/environment returning 503 during startup. Not sure whether it's related.
  • Related but not the same: #35048 (merged, portal restart reconnect), #28989 (open, Lua conflict detection), #23426 (Hyprland activation timeouts).

Question for maintainers: does the Hyprland-managed path (PortalCaptureShortcut with managedByHyprland) fail silently before CreateSession? A logged error at that point would make this easy to diagnose.
