David Castro <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #2 from David Castro <[email protected]> --- Same bug here, on different hardware and distro, still present on 6.8.0. Symptom The greeter comes up normally (login form and wallpaper both shown). The mouse works: I can click buttons, and clicking Login with the empty field fails with "Authentication failure". But the password field never shows a text cursor, not even after clicking into it, and typing inserts nothing. Caps Lock and Num Lock still toggle their LEDs, so the compositor is receiving the keys. Unplugging and replugging the keyboard does not help. Ctrl+Alt+F3 works, and running "systemctl restart plasmalogin" from the VT gives a greeter that accepts typing normally. Frequency First seen 2026-10-10. Since then it has failed on 6 of 14 boots, randomly. The next boot is usually fine. What I tested 1. Input method: plasma-keyboard is not installed here. I overrode plasma-login-kwin_wayland.service to start kwin_wayland without "--inputmethod plasma-keyboard" (confirmed with "systemctl --user show"). It still failed on 2026-10-21, so the input method does not seem to be the cause. 2. Window focus: I added an ExecStop= to plasmalogin.service that loads a KWin script over the greeter's session bus, so the dump runs just before the stuck greeter is killed. On the 2026-10-18 failure (6.7.5) it reported: workspace.activeWindow = plasma-login-greeter plasma-login-greeter wantsInput=true active=true plasma-login-wallpaper wantsInput=false active=false So KWin considers the greeter the active window while its text field shows no cursor and gets no input. That looks to me like the greeter's window never receives keyboard focus (wl_keyboard.enter) even though KWin has activated it. (On 6.8.0 the same dump comes back empty, because switching to the VT now removes the outputs first.) 3. Logs: with QT_LOGGING_RULES=kwin_*.debug=true on the greeter's KWin, a failing instance and the working one after the restart log the same things, apart from ordinary startup noise. Nothing input-related shows up. 4. Versions: it first appeared on 6.7.4/6.7.5 and still happens on 6.8.0 (rebuilt against Qt 6.12). System CachyOS (Arch-based), Wayland plasma-login-manager 6.8.0, KWin 6.8.0, Plasma 6.8.0, Frameworks 6.31.0 Qt 6.12.0, Mesa 26.2.4, libinput 1.32.0, kernel 7.2.11-1-cachyos Desktop: Intel i7-10700K, AMD Radeon RX 9070 XT 2x AOC 2590G4 (1920x1080 @ 144 Hz), wired DELL USB keyboard (413c:2005) I can attach the greeter user's journal for a failing and a working boot, or run any other diagnostics that would help. -- You are receiving this mail because: You are watching all bug changes.
