2025-09-10Wayland backend: desktop icons v2, menu rebuild, layer-shell/scale fixes,srdusr1-1/+69
XWayland stability, GPU rendering, and multi-cursor Phase 2 The bulk of a multi-session shift's real work landed in crates/wayland. Full root-cause/verification narrative for every item below lives in docs/TODO.md (each has its own dated entry); this is the summary: Desktop shell: - Real desktop icons v2 (state/desktop_icons.rs, desktop_icons.rs): fixed origin-baked-before-the-bar-connects, fixed-icon sort order, and a proper Rename/Delete-to-Trash menu (window_memory.rs backs the rename-persistence side). Rubber-band marquee multi-select. - icon_theme.rs: real freedesktop icon-theme lookup (inherits chain, hicolor fallback) rendering actual theme SVGs via resvg/tiny-skia, replacing the hand-drawn placeholder glyphs. - Context/desktop menus (decoration.rs, desktop_menu.rs, state/menu.rs) rebuilt to match the project's own AGS panel styling: rounded floating panel, tinted-fill row highlight, real separators, a much fuller titlebar window-menu action set. Layer-shell / multi-monitor: - Layer-shell hit-testing and render positioning (input/pointer.rs, udev/render.rs's element placement) now correctly convert LayerMap's logical geometry into physical pixels on a fractionally-scaled output - root cause of a bottom-anchored dock being unclickable and unpainted while a top-anchored bar on the same output worked. udev/outputs.rs's relayout_outputs gained the same physical/logical split for cross-output positioning, now backed by a real unit test (next_logical_x) built from the original measured incident numbers. - state/geometry.rs: a window's border/decoration no longer briefly clips when moved between differently-scaled monitors mid-drag. XWayland / stability: - xwayland.rs, udev/session.rs, udev/platform.rs: fixed a 100%- reproducible cold-start XKEYBOARD crash-loop (XWayland's own stdin inherited a real, already-owned VT; env passthrough and idle-callback spawn timing were both real, independent gaps) that had silently taken down all X11-app support and the global-menu registrar every session. - state/toplevel.rs, state/lifecycle.rs: XWayland dialog detection via WM_TRANSIENT_FOR, not just a native xdg_toplevel parent. Rendering: - udev/render.rs, decoration.rs: real GPU (GBM+EGL+DrmCompositor) window-content and cursor rendering on the udev backend, falling back to the untouched Pixman path automatically on any init failure. - decoration/tests.rs, state/mod.rs: rounded-corner/border fixes for interactive resize lag and cross-monitor moves. Multi-cursor Phase 2 (virtual_pointer.rs, new; state/mod.rs, udev/ platform.rs, winit/nested_platform.rs): pins a zwlr_virtual_pointer_ unstable_v1 object to a specific window, bypassing the shared seat/ focus/pointer_pos path entirely via hand-rolled wl_pointer.enter/motion/ button/frame/leave against every WlPointer the target client has bound (PointerHandle::client_pointers). Lets an agent operate one window while a human uses another, genuinely simultaneously, with zero client cooperation and no second wl_seat (confirmed a dead end: real clients only ever bind the first seat advertised). Full workspace build/test/clippy clean.
2025-08-17Fix desktop icons v1 regressions: bar overlap, wrong order; add proper menussrdusr1-2/+2
Live testing found v1 genuinely broken, not just rough: 1. Icons weren't rendering reliably at all - ensure_desktop_icons only ever computed the grid's origin once, on whichever render pass happened to be first. AGS's own top bar registers its exclusive zone after that first pass, so origin got permanently baked in at the pre-bar geometry. Confirmed live via a temporary diagnostic log. Fixed by re-deriving origin from the primary monitor's current geometry on every call instead of just the first. 2. Fixed icons (Home/Computer/Trash) always sorted before real files -- confirmed wrong via direct question. The whole list now sorts alphabetically by label, case-insensitive, fixed icons included. 3. "Set as Wallpaper" was the wrong feature: removed entirely (DesktopMenuAction::SetWallpaper, general.wallpaper_command, is_image_path). The user wants that handled by their real file manager once opened, not reimplemented here. Also adds real menu functionality per "where are all the options": Rename (inline text edit, new CompState::renaming_icon field and keyboard redirect mirroring NativeLock::password's existing precedent), Delete (moves to ~/.local/share/Trash per the freedesktop.org spec, new trash.rs module, same-filesystem case, no confirmation - this is the reversible move-to-trash, not a permanent delete), Empty Trash on the Trash icon, and Open Terminal Here / Open in File Manager on the bare-desktop menu (new general.terminal config key). 133 wayland-crate tests (up from 106), full workspace build and clippy clean.
2025-08-15Add real desktop icons plus right-click desktop/icon context menussrdusr1-0/+28
Closes "right-click on bare desktop" - previously a true no-op, nothing rendered above the wallpaper at all. Requested directly: a real desktop "just like windows does" - Home/Computer/Trash plus one icon per real ~/Desktop entry, individually draggable with persisted grid positions, double-click to open, right-click menus (per-icon "Open" plus "Set as Wallpaper" for image files when general.wallpaper_command is set; bare desktop "New Folder"/"Refresh"). Architecture mirrors the existing context_menu.rs/snap_flyout.rs "compositor-owned floating UI" pattern: desktop_icons.rs (data model, grid layout, filesystem scan, hit-test), desktop_icons_state.rs (JSON persistence, same shape as monitor_layout.rs), desktop_menu.rs (the new right-click menu, reusing decoration::render_context_menu's existing rasterizer), state/desktop_icons.rs (CompState glue: rescan/select/drag/ open/persist), and a new decoration::render_desktop_icon rasterizer -- hand-drawn glyphs, since no PNG/SVG decoding capability exists anywhere in this workspace. Wired into both render loops (udev and winit) above the wallpaper and below every window, and into input/pointer.rs's button/ motion handlers for selection, drag, double-click, and both menus. Four new config keys: general.desktop_icons (default true - a directly requested, purely visual feature, unlike the opt-in-while-experimental general.gpu), general.file_manager, general.desktop_icon_single_click, general.wallpaper_command (all default off/empty). Deliberately out of scope for this pass, stated up front: move-to-trash and "Empty Trash" (destructive, no confirmation-dialog primitive to gate them on yet), filesystem watching, multi-select, per-mimetype icon art, icons on any monitor but the primary one. 124 wayland-crate tests (up from 106), full workspace build and clippy clean.
2025-08-09Fix interactive-resize border/shadow lag without the OOB risk that sank the ↵srdusr1-3/+35
first attempt effective_frame_of now returns the live drag target while a window is being interactively resized (same change as the reverted first attempt), but two things make it safe this time instead of reintroducing the out-of-bounds texture sample that reversion was for: - Every src crop rect built from a window's frame width in udev/render.rs and winit/render.rs (titlebar, top border strip, bottom border strip) is now clamped against DecorationSignature's own recorded width/ border_width - the bitmap's actual last-built size - before reaching MemoryRenderBufferRenderElement::from_buffer, which does not itself validate src against the real texture size. This is a structural floor independent of timing, not a repeat of the previous unsafe approach. - handle_pointer_position now calls redraw_decoration_buffer once per resize motion event (throttled to 60Hz via a new CompState::resize_redraw_at), closing the lag at its source instead of only catching up on the next real client commit. This also fixes the shadow bitmap's identical commit-vs-live-position gap for free, since redraw_decoration_buffer rebuilds all three bitmaps together. Updates the TODO.md entry for this bug with the full before/after.
2025-08-08Render real window content on the GPU render pathsrdusr1-15/+30
Past clear-color + cursor: a GPU-driven head now renders every visible window's real content too, via surface_content_elements (the same generic-over-renderer helper the Pixman path uses, unmodified against gpu.renderer instead of udev.renderer). Content pushed after the cursor (so the cursor stays on top), in the same front-to-back `ids` order the Pixman path's own custom_elements already relies on for correct occlusion between windows - plain painter's-algorithm draw order, no separate clip needed since content is window-shaped. Deliberately the *unrounded* path: no corner masking (that's built against PixmanRenderer specifically on this backend) and no decorations (border, titlebar) - a GPU-driven head now shows real window content, square corners, no chrome. Decorations are the remaining real gap before this path has parity with the software one. Per-window geometry/position math (geom from window_anims or w.geometry, band for a decorated window's titlebar reservation, content_offset clamped non-negative) mirrors the Pixman path's own content push exactly, including an earlier double- subtraction and negative-margin fixes - so a CSD client with a real shadow margin positions the same way on either render path. Untested on real GPU-enabled hardware as of this writing: builds, passes clippy, full test suite green, and matches the existing Pixman path's geometry logic by inspection, but SRDWM_GPU/general.gpu were both unset on the machine this was built on - noted honestly in gpu.rs's own module doc comment, DEFAULTS.md, and IMPLEMENTATION_STATUS.md.
2025-05-26Render the real cursor on the GPU render path, not just a clear colorsrdusr1-11/+24
Past clear-color-only (Phase 2): the GPU-driven head now shows the same moving cursor the Pixman path renders, via cursor::render_elements - already generic over the renderer (R: Renderer + ImportAll + ImportMem), so it works unmodified against gpu.renderer (GlesRenderer) instead of udev.renderer (PixmanRenderer). GpuElement (gpu.rs) widened from a bare MemoryRenderBufferRenderElement to crate::elements::OverlayElement<GlesRenderer> - the same Surface/Memory/Solid enum the Pixman path's own custom_elements already uses, needed once the element list stopped always being empty. Window content and decorations remain a real gap - a GPU-driven head still shows no windows, just its own clear color and cursor. Untested on real GPU-enabled hardware this work (SRDWM_GPU unset on this machine's live session); builds, passes clippy, full test suite green.
2025-05-15Extend GPU rendering to every head, not just the firstsrdusr1-22/+28
Phase 2 of the GPU-rendering plan deliberately targeted a single head (GpuContext::output: Option<(crtc::Handle, GpuOutput)>) as a narrow proof that GBM+EGL+DrmCompositor rendering works at all on this hardware. DrmOutputManager already supports driving several crtcs at once - initialize_output is a per-crtc call on one shared manager, the same way anvil drives multiple outputs - so this was purely an unexercised restriction, not an architectural limit. GpuContext::output is now GpuContext::outputs: Vec<(crtc::Handle, GpuOutput)>, and udev/platform.rs calls initialize_output for every connected head in its own bring-up loop instead of only the first after that loop finishes. A head this fails for individually (already logged, not fatal) still just has no entry and falls back to the existing legacy Pixman path, unchanged from before. session.rs's VBlank handler and its VT-switch resume path (which excludes GPU-driven crtcs from the legacy set_crtc reassert loop, a different device fd that must never issue mode-set commands against a crtc DrmOutputManager already owns) both now look a crtc up in the Vec instead of comparing against a single stored one. render.rs's own render-loop lookup uses direct field access (gpu.outputs.iter_mut().find(...)) rather than an equivalent &mut self method: the borrow checker treats a method call as borrowing all of GpuContext, including gpu.renderer needed a few lines later for the same head, where direct field access lets it see the two borrows are disjoint. Still gated behind SRDWM_GPU=1 (unset by default) and untested on real multi-monitor hardware with the flag on - this machine has one display, so the actual multi-head path itself only gets exercised whenever it's set on hardware that has more than one.
2025-04-29Fix border/content misalignment from a stale and double-applied CSD marginsrdusr1-4/+63
Two bugs in how a CSD client's own declared shadow-margin offset (dwindow.geometry().loc) drives where its content actually renders, both surfaced by a real Firefox window: 1. A live Firefox window was observed reporting loc = (-10, -10) -- negative, despite sync_geometry's tiled-state hint telling it to reserve no margin at all. effective_frame_of already clamps this value to non-negative for its own size calc; the content-position code (both the masked-content-buffer test and the real content push) didn't, so a negative margin shifted content the wrong way -- away from the border, not toward it. Clamped to match. 2. Separately, and the actual cause of a later "border isn't over the window" report on the same Firefox window (this time reporting loc = (10, 10)): the masked/rounded content buffer's own build step already renders the client's surface tree shifted by -content_offset so the buffer's own (0, 0) lands exactly on the real, margin- excluded content top-left (see rounded_content_buffer's own loc parameter). Placing that already-compensated buffer on screen at a *second* content_offset-shifted position double-applied the correction, landing it content_offset pixels too far up and left of the border wrapping it. Confirmed live via pixel sampling: Firefox's own chrome rendered starting 10px above the border's nominal top edge, fully exposed, square, with no border over it at all. Split the single `pos` into `content_pos` (unshifted - what the already-compensated masked buffer uses) and `pos` (content_pos further shifted by content_offset - kept only for the surface_content_elements fallback, which renders the client's raw surface tree with no prior compensation of its own and still needs the shift applied once). The winit/GLES backend's equivalent path doesn't have this bug: its rounded_content_element renders the client's live texture directly at `location` with no separate pre-shifted buffer, so a single content_offset-adjusted position there was already correct.
2025-03-26Wire real GBM+EGL+DrmCompositor rendering for one head (GPU Phase 2)srdusr1-0/+29
Extends the SRDWM_GPU=1 opt-in path (Phase 1, fa0c7f1) from a capability probe into an actual, working GPU render pipeline for exactly one head, per the plan this was built from the plan file. gpu.rs: probe now goes all the way through EGLContext, GlesRenderer, DrmDevice (real DRM device, separate duped fd from the existing legacy Card), and DrmOutputManager construction, returning both a GpuContext and its DrmDeviceNotifier on success. GpuContext::initialize_output drives one crtc/mode/connector through DrmOutputManager, storing the resulting GpuOutput for the render loop to find. Confirmed while reading smithay's own source directly (not assumed): DrmDevice::new's disable_connectors parameter is not an atomic-vs- legacy switch - DrmDevice::create_internal tries atomic capability first and falls back to a Legacy internal variant automatically, exposed via DrmDevice::is_atomic(), logged here rather than assumed. platform.rs: probes at startup, calls initialize_output for the first head only (Phase 2's deliberate scope - see the plan), registers the DrmDeviceNotifier as its own calloop event source alongside (not replacing) the existing legacy DRM-fd registration. render.rs: render_udev_frame's per-head loop checks, before any of the existing Pixman-specific element-building logic runs, whether this head's crtc matches the GPU context's initialized output; if so, renders a plain clear color through render_frame/queue_frame and continues to the next head, completely bypassing the Pixman path for that head. Every other head, and this same head whenever the GPU context or its output is absent, is entirely unaffected. session.rs: register_gpu_drm_notifier handles DrmEvent::VBlank by calling frame_submitted() on the matching GpuOutput (required per queue_frame's own doc comment, or the swapchain runs out of buffers) and logs DrmEvent::Error without treating it as fatal. Deliberately out of scope for this phase (documented in the plan): window content/decorations/cursor on the GPU head (clear color only), multi-monitor GPU rendering (one head only), and VT-switch pause/ resume for the GPU head specifically (DrmOutputManager's own pause()/ activate() calls are a different API surface from the existing manual set_crtc+DPMS reassertion, and porting that pairing correctly needs its own isolated verification pass). SRDWM_GPU unset (the default) is unaffected: every step above only runs when it's set to "1", and every failure at any step falls back to the existing, untouched Pixman path with a logged reason, same fallback contract Phase 1 already established.
2025-03-07Fix stale ghost content after window move/resize/close on real hardwaresrdusr1-1/+43
The udev backend's damage tracking only forced a full repaint (ages = [0, 0]) on a workspace switch or a VT-switch resume. An ordinary move/resize/open/close/restack within the same workspace relied entirely on OutputDamageTracker's own per-element diffing to compute correct damage for the region a window vacated - which doesn't always hold: maximizing a window over a second one, then un-maximizing, left a persistent ghost of the second window's old titlebar/status text sitting in the vacated corner, unchanged across multiple otherwise- idle frames. render_udev_frame now also hashes every visible window's id and rect each frame and forces the same full-repaint reset whenever that signature changes - the same "defensive, not a fix for a proven bug in the diffing itself" reasoning the existing workspace-switch reset already uses, just triggered by a second, complementary condition.
2025-02-21Remove resolved corner-rounding diagnosticssrdusr1-29/+0
The top-rounds-but-bottom-doesn't investigation these were tracking is closed: live-verified via a real screenshot (pixel-level, not eyeballed) that both corners round correctly on both a decorated window and an undecorated/CSD one relying on content masking. Removes three log::debug! blocks (corner-mask state, TOP/BOTTOM border strip position dumps, and a raw alpha-byte dump of the bottom border buffer) that were firing on every single render pass regardless of whether anything changed, adding real per-frame overhead for output no longer needed. Build + clippy + test (378 passing) all still green.
2025-02-18Fix clippy warnings surfaced by the mergesrdusr1-1/+2
Pre-existing issues in the uncommitted rust-rewrite work (unused imports, over-arity glyph-drawing functions, a couple of complex inline types, or_insert_with(T::default) instead of or_default(), and one unsimplified test-only arithmetic expression), plus two imports left unused by switching to or_default(). None of these are behavior changes. Full workspace build + clippy -D warnings + test suite (378 tests) all green after this.

2025-02-17Checkpoint: today's fixes before reconciling with the rust-rewrite worktreesrdusr1-12/+46
Fixes a live-reproduced VT-switch busy loop (failed page_flip retried with no backoff), shadow rendering bleeding onto occluding windows unclipped, and a winit-backend buffer-age correctness bug that left stale cross-window pixels on screen. Committing before merging in the much larger uncommitted rust-rewrite worktree, which independently touches several of the same files - this is the pre-merge baseline to diff against, not a claim that these are the final versions of these fixes.
2025-02-15Checkpoint: preserve all uncommitted rust-rewrite worktree worksrdusr1-75/+409
Safety commit before reconciling this worktree with main, which has diverged with its own separate fixes today. Nothing here is reviewed or curated yet - this exists purely so none of this work can be lost to a git operation, disk issue, or worktree cleanup while that reconciliation happens.
2025-02-04Fix CSD windows rendering with a wallpaper-visible gap at their cornersrdusr1-1/+24
srdwm never read xdg_surface.set_window_geometry anywhere. A CSD client (GTK4/Firefox) declares its real visible content as a sub-rect inset within a larger buffer that also reserves an invisible shadow margin - that margin stays reserved in the buffer even once the tiled-state hint tells the client to stop drawing the shadow itself. Every render path was positioning content at the client's raw buffer origin instead of subtracting that declared offset, leaving the margin's width/height as a gap with wallpaper visible through it at the window's top-left corner. Confirmed by pixel-diffing the gap against the real wallpaper at that exact screen position: an exact match, ruling out "just the client's own dark theme." Fixed in three places that have to move together: udev/render.rs and winit/render.rs's content-positioning code, and sync_geometry's space.map_element call. That last one matters as much as the other two - it's what smithay's Space (and therefore click hit-testing) reads, so a render-only fix would have traded a visible gap for an invisible, same-size hit-test offset in the other direction. Also applied to the new capture-workspace off-screen render for the same reason. This likely also explains real dropdown/context-menu misplacement (and the clicks landing on the wrong spot) in CSD apps: popup positioning anchors against the same window position this fix corrects.
2024-12-24Accumulate wayland-crate additions: capture rendering, focus/Space sync, VT ↵srdusr1-6/+78
resume, plumbing Bundles the remaining wayland-crate changes built up here, touching both backends (udev and winit) and the shared input/rendering code: - udev/capture.rs: off-screen Pixman render of an arbitrary (not necessarily on-screen) workspace's window content to a PPM file -- what crates/core's capture-request queue drives, for a workspace switcher's thumbnail previews. wlr-screencopy structurally can't do this (it can only see what an output is presenting), which is why this exists as a separate render path rather than reusing it. - input::focus_window now also raises the window in smithay's own Space, not just core's stacking order - Space is what actually renders on top and what pointer hit-testing reads, so any focus path that skipped this (an IPC "focus" dispatch, concretely) left a window genuinely focused while still rendering, and receiving clicks, underneath whatever was already topmost. Both backends' poll loops now re-sync this after any IPC mutation. - udev/session.rs's VT-switch resume fix (drains a stale pending page flip before reasserting CRTCs) already has its own earlier, cleanly isolated commit - not duplicated here. - Assorted decoration/cursor/rounded-corners/output-management/ screencopy/XWayland changes and their cross-backend wiring. Coarser than the repo's usual one-purpose-per-commit convention, deliberately - see the core-crate sweep commit's own message for why.
2024-08-23Round the bottom border strip's corners to match the topsrdusr1-8/+21
MISSING.md listed the border frame's bottom/left/right strips as staying square while the top one (and the titlebar above it) rounds -- "unrelated to client content rounding... not attempted." The left/ right strips genuinely can't participate (border_strips' geometry has them span only the height between the top and bottom strips, no corner to round), but the bottom strip is exactly the same shape as the top one and had no reason left to stay square. decoration::render_border_bottom mirrors render_border_top exactly (round_bottom_corners mirrors round_top_corners), cached the same way in a new border_bottom_decorations map, and drawn in both render loops via the same all-or-nothing occlusion check the top strip already uses - pulled out of the left/right strips' per-fragment occlusion splitting into its own dedicated bitmap path, matching top's existing trade-off (cropping a rounded bitmap's source rect per fragment is real extra work for a strip this thin) rather than inventing a new one. One real bug caught before it shipped: round_bottom_corners' corner- centre math (height - r - 1) panics on unsigned underflow whenever the radius clamp lands on the strip's own full height (a real, common case - a 2px-thick test strip hits it immediately). Fixed by computing the centre as a signed offset instead, mirroring how the existing dx/dy distance math already avoids the same class of issue.
2024-08-03Fix doc-comment file references left stale by today's six module splitssrdusr1-2/+2
~17 comments across the codebase still pointed at udev.rs/winit.rs/ state.rs by their old flat-file names after those became udev/, winit/, state/ directories - found while auditing what this work rushed, since the split verification (function/struct-name diffing, full test suite) checked structural correctness but never comment accuracy. Updated each to either the specific new file (e.g. "see state.rs's REPEAT_DELAY" -> "see state/mod.rs's REPEAT_DELAY", "udev.rs's monitors()" -> "udev/platform.rs's monitors()") or the bare module name where the reference was already generic ("the udev/winit backends", not a specific location).
2024-07-16Split crates/wayland/src/udev.rs (1643 lines) into udev/srdusr1-0/+600
Pure reorganization, no behavior change - verified by diffing the function-name and struct-name sets before/after (both identical) plus a full cargo test pass. Struct definitions (Card, DrmBuffer, UdevHead, UdevState) and their small impls stay in mod.rs, since default (crate- scoped) privacy there is visible to every descendant submodule without further changes. The rest splits by concern: - render.rs: the per-frame impl CompState block (render_udev_frame and the gamma/output-power methods) - still one ~520-line function, left intact rather than decomposed, given how much of its structure (the self.udev.as_mut() disjoint-borrow pattern threaded through it) is deliberate and already documented inline. - outputs.rs: hotplug reprobe/relayout (impl CompState). - platform.rs: UdevPlatform's struct/connect logic and its `impl Platform for UdevPlatform`, previously split apart in the flat file by ~250 lines of unrelated DRM/session code sitting between them. - drm.rs: mode/CRTC/framebuffer probing and setup. - session.rs: libseat/libinput/udev-monitor calloop registration and the libinput event handler. A few free functions and one struct (ConnectorProbe, bring_up_head, probe_connected, pick_crtc, the register_* functions) went from module-private to pub(crate): called across what are now sibling submodules, which - unlike a defining module's own descendants -- Rust's privacy model doesn't let see each other's private items. Matches this crate's existing pub(crate) convention rather than introducing pub(super), which crates/core's manager/ split used instead to match *that* crate's plain-private convention.
