<div dir="ltr"><div>Package: mutter<br>Version: 51.0-3<br>Severity: normal<br><br>Dear Maintainer,<br>In Debian Sid with mutter/gnome-shell 51.0-3, starting a GNOME Wayland session <br>via LightDM or switching sessions triggers a seat device management failure in <br>mutter's native backend.<br><br>Symptoms:<br>1. Wireless HID++ input devices (Logitech Unifying 046d:c52b and Logi Bolt 046d:c548) <br> lose input focus and the mouse cursor becomes invisible, while standard USB tablet <br> devices remain functional.<br>2. Logging out of the broken GNOME session back to LightDM fails to cleanly release <br> DRM/seat devices, causing subsequent login attempts (even on a clean test user or <br> switching to KDE Plasma) to hang on an unresponsive black screen until a full reboot.<br><br>Relevant journalctl log output during session startup/transition:<br>gnome-shell[13909]: ../../../gobject/gsignal.c:2674: handler '36' of instance '0x55ac738b8f00' is not blocked<br>gnome-shell[13909]: meta_renderer_resume: assertion 'priv->is_paused' failed<br>gnome-shell[13909]: Spurious call to meta_seat_native_reclaim_devices() without previous call to meta_seat_native_release_devices<br>gsd-xsettings[15571]: Failed to get current UI scaling factor: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Name "org.gnome.Mutter.X11" does not exist<br><br>Workaround found:<br>Switching the display manager from LightDM back to GDM3, performing a clean reboot, <br>and avoiding background HID-polling conflicts at login restores normal seat <br>initialization.<br><br>-- System Information:<br>Debian Release: forky/sid<br> APT prefers unstable<br> APT policy: (500, 'unstable'), (100, 'testing')<br>Architecture: amd64 (x86_64)<br><br>Kernel: Linux 7.3.3+deb14-amd64 (SMP w/24 CPU threads; PREEMPT)<br>Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE<br>Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set<br>Shell: /bin/sh linked to /usr/bin/dash<br>Init: systemd (via /run/systemd/system)<br>LSM: AppArmor: enabled<br><br>Versions of packages mutter depends on:<br>ii adwaita-icon-theme 51.0-1<br>ii gnome-settings-daemon-common 51.0-2<br>ii gsettings-desktop-schemas 51.0-2<br>ii libc6 2.43-7<br>ii libglib2.0-0t64 2.90.1-2<br>ii libmutter-51-0 51.0-3<br>ii mutter-common 51.0-3<br><br>mutter recommends no packages.<br><br>Versions of packages mutter suggests:<br>ii gnome-control-center 1:51.1-2<br>ii xdg-user-dirs 0.20-1<br><br>-- no debconf information</div><div><br></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">
