--- Begin Message ---Package: gdm3 Version: 3.22.3-4 Severity: important Dear Maintainer, For a few months I am unable to login using gdm3. The greeter shows up normally, but upon entering login information the screen flickers and the system becomes barely-responsive for a few minutes, until I am left with a bare TTY login prompt - this appears to be the result of gnome/gdm3 frantically retrying and failing to start. The X.org log contains the following info: (WW) xf86OpenConsole: VT_ACTIVATE failed: Operation not permitted (EE) Fatal server error: (EE) xf86OpenConsole: Switching VT failed However, using lightdm I can login fine, so this does not seem to be an X.org or driver-related problem, but rather something about gdm3. Installing xserver-xorg-legacy does not solve this issue, however it did produce a dmesg line about a segfault in libgtk-3-0.so. Reinstalling `libgtk-3-0` got rid of the segfault, but still no luck - now with `xserver- xorg-legacy` installed I'm getting the following in demsg: traps: gdm3[1318] general protection ip:564e456e74c2 sp:7ffc3c4017c0 error:0 in gdm3[564e456ce000+5d000] Reinstalling gdm3 does not get rid of this message, and I am still unable to login when using gdm - getting a constant flicker for about a minute until it finally gives up. At the same time, lightdm manages to log in without any problem. The system has an integrated Intel graphics (Ivybridge / Intel HD4000), and no other graphics adapter installed. I'm using the KMS driver. The problem only occured after the update to 3.22.3-2, so this does not seem to be a duplicate of bug #857995 -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (990, 'testing'), (700, 'unstable'), (500, 'testing-debug') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.11.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages gdm3 depends on: ii accountsservice 0.6.43-1 ii adduser 3.115 ii dconf-cli 0.26.0-2+b1 ii dconf-gsettings-backend 0.26.0-2+b1 ii debconf 1.5.63 ii gir1.2-gdm-1.0 3.22.3-4 ii gnome-session [x-session-manager] 3.22.3-1 ii gnome-session-bin 3.22.3-1 ii gnome-session-flashback [x-session-manager] 3.22.0-3 ii gnome-settings-daemon 3.22.2-5 ii gnome-shell 3.22.3-3 ii gnome-terminal [x-terminal-emulator] 3.22.2-1 ii gsettings-desktop-schemas 3.22.0-1 ii libaccountsservice0 0.6.43-1 ii libaudit1 1:2.7.7-1+b2 ii libc6 2.24-12 ii libcanberra-gtk3-0 0.30-3 ii libcanberra0 0.30-3 ii libgdk-pixbuf2.0-0 2.36.5-2 ii libgdm1 3.22.3-4 ii libglib2.0-0 2.52.3-1 ii libglib2.0-bin 2.52.3-1 ii libgtk-3-0 3.22.16-1 ii libkeyutils1 1.5.9-9 ii libpam-modules 1.1.8-3.6 ii libpam-runtime 1.1.8-3.6 ii libpam-systemd 234-2 ii libpam0g 1.1.8-3.6 ii librsvg2-common 2.40.18-1 ii libselinux1 2.6-3+b2 ii libsystemd0 234-2 ii libwrap0 7.6.q-26 ii libx11-6 2:1.6.4-3 ii libxau6 1:1.0.8-1+b2 ii libxcb1 1.12-1 ii libxdmcp6 1:1.1.2-3 ii lsb-base 9.20161125 ii metacity [x-window-manager] 1:3.24.1-1 ii mutter [x-window-manager] 3.22.4-2 ii policykit-1 0.105-18 ii twm [x-window-manager] 1:1.0.9-1+b1 ii ucf 3.0036 ii x11-common 1:7.7+19 ii x11-xserver-utils 7.7+7+b1 ii xfce4-session [x-session-manager] 4.12.1-5 ii xfce4-terminal [x-terminal-emulator] 0.8.5.1-1 ii xfwm4 [x-window-manager] 4.12.4-1 ii xterm [x-terminal-emulator] 330-1 Versions of packages gdm3 recommends: ii at-spi2-core 2.24.1-1 ii desktop-base 9.0.5 ii x11-xkb-utils 7.7+3+b1 ii xserver-xephyr 2:1.19.3-2 ii xserver-xorg 1:7.7+19 ii zenity 3.22.0-1+b1 Versions of packages gdm3 suggests: ii gnome-orca 3.24.0-1 ii libpam-gnome-keyring 3.20.1-1 -- Configuration Files: /etc/gdm3/PreSession/Default changed [not included] /etc/gdm3/daemon.conf changed [not included] -- debconf information: * shared/default-x-display-manager: lightdm gdm3/daemon_name: /usr/sbin/gdm3
