Package: gdm3 Version: 3.38.2.1-1 Followup-For: Bug #987040 I have now found the trigger for the locks: This always happens when I have a sshfs connection open at the time when going to suspend. The sshfs connection needs an established vpn, which isn't there when returning from suspend. As soon as the user logs in (pressing "Enter" in the screensaver dialog), the unavailable sshfs connection seems to lock gdm3 completely. It is actually not a complete hard-lock, playing music when going to suspend just continues after waking up and also after gdm3 has locked.
It seems that sshfs is known to have this kind of problems (#571005), but I guess gdm3 should not lock in this (or any) kind of situation ... -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (990, 'testing'), (500, 'testing-security'), (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-6-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages gdm3 depends on: ii accountsservice 0.6.55-3 ii adduser 3.118 ii dbus 1.12.20-2 ii dconf-cli 0.38.0-2 ii dconf-gsettings-backend 0.38.0-2 ii debconf [debconf-2.0] 1.5.75 ii gir1.2-gdm-1.0 3.38.2.1-1 ii gnome-session [x-session-manager] 3.38.0-4 ii gnome-session-bin 3.38.0-4 ii gnome-session-common 3.38.0-4 ii gnome-settings-daemon 3.38.1-3 ii gnome-shell 3.38.4-1 ii gnome-terminal [x-terminal-emulator] 3.38.3-1 ii gsettings-desktop-schemas 3.38.0-2 ii libaccountsservice0 0.6.55-3 ii libaudit1 1:3.0-2 ii libc6 2.31-11 ii libcanberra-gtk3-0 0.30-7 ii libcanberra0 0.30-7 ii libgdk-pixbuf-2.0-0 2.42.2+dfsg-1 ii libgdm1 3.38.2.1-1 ii libglib2.0-0 2.66.8-1 ii libglib2.0-bin 2.66.8-1 ii libgtk-3-0 3.24.24-3 ii libkeyutils1 1.6.1-2 ii libpam-modules 1.4.0-7 ii libpam-runtime 1.4.0-7 ii libpam-systemd 247.3-3 ii libpam0g 1.4.0-7 ii librsvg2-common 2.50.3+dfsg-1 ii libselinux1 3.1-3 ii libsystemd0 247.3-3 ii libx11-6 2:1.7.0-2 ii libxau6 1:1.0.9-1 ii libxcb1 1.14-3 ii libxdmcp6 1:1.1.2-3 ii lsb-base 11.1.0 ii mutter [x-window-manager] 3.38.4-1 ii policykit-1 0.105-30 ii procps 2:3.3.17-5 ii ucf 3.0043 ii x11-common 1:7.7+22 ii x11-xserver-utils 7.7+8 Versions of packages gdm3 recommends: ii at-spi2-core 2.38.0-2 ii desktop-base 11.0.3 ii x11-xkb-utils 7.7+5 ii xserver-xephyr 2:1.20.10-3 ii xserver-xorg 1:7.7+22 ii zenity 3.32.0-6 Versions of packages gdm3 suggests: pn gnome-orca <none> pn libpam-fprintd <none> ii libpam-gnome-keyring 3.36.0-1 -- debconf information excluded
