Package: gdm3 Version: 49.2-3 Severity: critical Justification: breaks the whole system X-Debbugs-Cc: [email protected]
Dear Maintainer, I updated my sid system and can no longer log in. I use gdm3 with the default GNOME wayland based session. After I enter my password or used the fingerprint sensor I got kicked right back to the login prompt. I looked through logs and saw this kind of thing: Jan 14 08:36:37 frau gnome-shell[3175]: Failed to start X Wayland: Wrong ownership for directory "/tmp/.X11-unix", owned by 60578 but should be same as /tmp (owned by (0)) or 1000 Jan 14 08:36:37 frau gnome-shell[3175]: == Stack trace for context 0x558653b20710 == Jan 14 08:36:37 frau systemd[2430]: [email protected]: Main process exited, code=killed, status=5/TRAP Jan 14 08:36:37 frau systemd[2430]: [email protected]: Failed with result 'signal'. Jan 14 08:36:37 frau systemd[2430]: Failed to start [email protected] - GNOME Shell on Wayland. When I looked, indeed /tmp/.X11-unix is owned by the gdm greeter user and there are two unix domain sockets owned by the gdm greeter user, and an instance of Xwayland running as that user. After some hackery I was able to run xlsclients against the two display sockets and they just show: frau ibus-x11 frau mutter-x11-frames Using xprop I determined that they're from programs of the same name under /usr/lib/libexec/, running as the gdm greeter user. I can mitigate this by running the following as root from a virtual console after I boot: chown root:root /tmp/.X11-unix chmod a+w /tmp/.X11-unix and then everything works fine. But this isn't ideal for me, or anyone else in the same situation. I'm not sure what's changed - whether there's always been an Xwayland server running in the gdm greeter session, or whether the way it's launched as changed or what. FYI, my xwayland package version is 2:24.1.9-1 since that might be relevant and it's not a dependency of gdm3 so not shown below. -- System Information: Debian Release: forky/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.18.3+deb14-amd64 (SMP w/24 CPU threads; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set 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 23.13.9-8 ii dbus [default-dbus-system-bus] 1.16.2-2 ii dbus-bin 1.16.2-2 ii dconf-cli 0.49.0-4 ii dconf-gsettings-backend 0.49.0-4 ii debconf [debconf-2.0] 1.5.91 ii gir1.2-gdm-1.0 49.2-3 ii gnome-session [x-session-manager] 49.2-3 ii gnome-session-bin 49.2-3 ii gnome-session-common 49.2-3 ii gnome-settings-daemon 49.1-4 ii gnome-shell 49.2-2 ii gnome-terminal [x-terminal-emulator] 3.58.1-2 ii gsettings-desktop-schemas 50~alpha-1 ii libaccountsservice0 23.13.9-8 ii libaudit1 1:4.1.2-1+b1 ii libc6 2.42-7 ii libgdm1 49.2-3 ii libglib2.0-0t64 2.86.3-4 ii libglib2.0-bin 2.86.3-4 ii libgudev-1.0-0 238-7 ii libjson-glib-1.0-0 1.10.8+ds-2 ii libkeyutils1 1.6.3-6 ii libnss-systemd 259-1 ii libpam-modules 1.7.0-5 ii libpam-runtime 1.7.0-5 ii libpam-systemd [logind] 259-1 ii libpam0g 1.7.0-5 ii librsvg2-common 2.61.3+dfsg-3 ii libselinux1 3.9-2 ii libsystemd0 259-1 ii libxau6 1:1.0.11-1 ii libxcb1 1.17.0-2+b1 ii polkitd 127-1 ii procps 2:4.0.4-9 ii ptyxis [x-terminal-emulator] 49.2-4 ii systemd [systemd-sysusers] 259-1 ii systemd-sysv 259-1 ii ucf 3.0052 ii x11-common 1:7.7+26 ii x11-xserver-utils 7.7+11 ii xterm [x-terminal-emulator] 406-1 Versions of packages gdm3 recommends: ii at-spi2-core 2.59.0-1 ii desktop-base 14.0.0~pre2 ii gnome-session [x-session-manager] 49.2-3 ii x11-xkb-utils 7.7+9 ii zenity 4.1.99-1 Versions of packages gdm3 suggests: ii libpam-fprintd 1.94.5-2 ii libpam-gnome-keyring 48.0-5 pn libpam-pkcs11 <none> pn libpam-sss <none> ii orca 49.5-1 -- debconf information: gdm3/daemon_name: /usr/sbin/gdm3 * shared/default-x-display-manager: gdm3
