greetd only launches the session after the greeter process exits. Quit
on successful StartSession instead of sitting on "Starting session…"
until SIGTERM.
Empty Secret/Visible answers are Some("") (not PAM cancel). The greetd
actor stays up across connect failure and reconnects. Escape cancels
the conversation. Session env sets XDG_SESSION_TYPE/DESKTOP. .desktop
parsing honors Hidden/NoDisplay/TryExec and quoted Exec=. Invalid TOML
warns instead of failing silent. Font, date, and Ken Burns config match
what the greeter actually draws.
Show MPRIS now-playing and upower battery under the clock, polled on a
background thread (zbus). Flags gate both drawing and D-Bus; desktops
without a battery stay blank; titles are truncated.
Also the locker audit pass that landed in the same files:
- PAM authenticates getuid()/getpwuid_r, not $USER, and missing
username still takes the lock
- one lock surface per output, generation-gated fail timers, PAM
timeout, Tab-reveal off by default and cleared on keyboard leave
- GPU chrome is a dirty-rect quad with EGL cleanup; shm reuses a
SlotPool; appear/shake/flash/veil/clock-crossfade bugs
- hold-to-reveal, checking ellipsis, and password display length
Live-checked on hermes (GPU path, PAM unlock, Tab-hold).
The Ken Burns wallpaper pan and dim veil move to the GPU: the lock
surface is wrapped in a wl_egl_window, the wallpaper is a textured quad
whose shader applies the pan transform and veil (GPU bilinear makes
sub-pixel panning free — the ~19ms/frame software bilinear is gone,
idle CPU drops from 40% to ~0%), and the clock/pill/status chrome is
still composed with tiny-skia and composited over. EGL init failure
falls back to the fully-software path unchanged.
Notable fixes along the way:
- Text blending is now destination-aware: the old blend forced output
alpha to 255, which is correct over the opaque background but made
every glyph opaque in the chrome-only pixmap the GPU path composites.
- wayland-client switches to its C backend for raw surface pointers,
and khronos-egl/glow replace a hand-rolled EGL loader.
Tests grew from 72 to 88: GPU pan_region parity with the software path
(and edge/bounds/corner invariants), shader-uniform/EGL-attrib sanity,
chrome bounding-rect tracking, and a pixel-level parity test proving
the GPU split stays within double-rounding ULP range of the single-pass
compose.
Adds a full motion system to the lock screen (staggered entrance, dot pop
+ caret, wrong-password shake, success flash, clock crossfade), depth
polish (gradient veil, pill shadow + hairline border, "Enter password"
hint, responsive typography), and a second wave of animations (idle
breathing, success dot cascade, status slide-in, parallax unlock drift,
animated checking ellipsis, opt-in Ken Burns wallpaper pan). Includes a
dev-only breadlock-preview harness that renders every state to PNGs with
no Wayland involved, and a design/sketch.html prototype.
Fixes text alpha being dropped by cosmic-text's glyph-mask path (all text
fades now work) and double-drifting that made the date/status overlap the
clock/pill during unlock.
Pulls the fix for panels turning brown/off-hue when pywal extracts a light
or muddy background from the wallpaper — background/surface now stay BOS's
fixed dark constants regardless of what the wallpaper looks like.
