Troy Latchman <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #9 from Troy Latchman <[email protected]> --- Possibly another manifestation of this same issue, on identical versions (Fedora 44, Plasma 6.7.4, NVIDIA 610.57.04) but hitting the `plasmalogin` greeter at boot instead of a running desktop session. On my system the greeter's own KWin instance (`plasma-login-kwin_wayland`) occasionally fails an atomic commit shortly after starting, crashes, and is restarted by systemd. When that happens, the already-rendered password field stays visible and still responds to mouse input, but no longer accepts keyboard input — clicking any other UI element (e.g. "Switch User") forces the greeter to rebuild the affected UI and restores keyboard input. I don't get a full freeze like the desktop case above; the greeter's automatic restart seems to recover the display layer but not the password field's input wiring. `atomic commit failed: Permission denied` shows up in the journal on nearly every greeter start (found in ~15-20 occurrences across two weeks of logs), but the user-visible dead-keyboard symptom is much rarer (noticed twice) — consistent with this being a timing-dependent consequence of the same underlying register/commit issue rather than a separate bug: most of the time KWin's retry lands before the QML password field finishes wiring up input, so the race is invisible in practice.
