Package: gdm Version: 2.20.9-1 Severity: important
Attempting to run a nested desktop with: /usr/share/gdm/applications/gdmflexiserver-xnest.desktop fails silently. The same is true when using the System->Log Out->Switch User menu option in GNOME. I was unable to locate any error messages in any system logs, as the default audit level in the gdm configuration appears to be 0. However, some manual investigation with both Xnest and Xephyr shows that this is some kind of authorization error: $ Xnest :22 & xterm -display :22 & [1] 19632 [2] 19633 u...@localhost:~$ Could not init font path element /usr/share/fonts/X11/cyrillic, removing from list! AUDIT: Mon Jun 15 02:33:03 2009: 19632 Xnest: client 1 rejected from local host (uid 2000) No protocol specified xterm Xt error: Can't open display: :22 Note that XAUTHORITY is in the environment, and that this error is true whether xhost is allowing all hosts or not. The only way to get Xnest or Xephyr on my system to run is by passing the -ac flag, which turns off all access control, which is not really what a reasonable person would want. -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (990, 'testing'), (700, 'unstable'), (600, 'stable'), (550, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.26-2-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages gdm depends on: ii adduser 3.110 add and remove users and groups ii awesome [x-window-mana 3.3-1 highly configurable, next generati ii debconf [debconf-2.0] 1.5.26 Debian configuration management sy ii dwm [x-window-manager] 5.5-1 dynamic window manager ii gksu 2.0.2-2+b1 graphical frontend to su ii gnome-session [x-sessi 2.22.3-3 The GNOME 2 Session Manager ii gnome-terminal [x-term 2.26.2-1 The GNOME terminal emulator applic ii ion3 [x-window-manager 20090110-1 tiling tabbed window manager desig ii kde-window-manager [x- 4:4.2.2-2 the KDE 4 window manager (KWin) ii konsole [x-terminal-em 4:4.2.2-1 X terminal emulator for KDE 4 ii larswm [x-window-manag 7.5.3-6 Lars Window Manager with tiled win ii libart-2.0-2 2.3.20-2 Library of functions for 2D graphi ii libatk1.0-0 1.26.0-1 The ATK accessibility toolkit ii libattr1 1:2.4.43-2 Extended attribute shared library ii libc6 2.9-12 GNU C Library: Shared libraries ii libcairo2 1.8.6-2+b1 The Cairo 2D vector graphics libra ii libdbus-1-3 1.2.12-1 simple interprocess messaging syst ii libdbus-glib-1-2 0.80-4 simple interprocess messaging syst ii libdmx1 1:1.0.2-3 X11 Distributed Multihead extensio ii libfontconfig1 2.6.0-3 generic font configuration library ii libfreetype6 2.3.9-4.1 FreeType 2 font engine, shared lib ii libglade2-0 1:2.6.4-1 library to load .glade files at ru ii libglib2.0-0 2.20.1-2 The GLib library of C routines ii libgnomecanvas2-0 2.26.0-1 A powerful object-oriented display ii libgtk2.0-0 2.16.1-2 The GTK+ graphical user interface ii libpam-modules 1.0.1-9 Pluggable Authentication Modules f ii libpam-runtime 1.0.1-9 Runtime support for the PAM librar ii libpam0g 1.0.1-9 Pluggable Authentication Modules l ii libpango1.0-0 1.24.0-3+b1 Layout and rendering of internatio ii librsvg2-2 2.22.3-2 SAX-based renderer library for SVG ii librsvg2-common 2.22.3-2 SAX-based renderer library for SVG ii libselinux1 2.0.71-1 SELinux shared libraries ii libwrap0 7.6.q-16 Wietse Venema's TCP wrappers libra ii libx11-6 2:1.2.1-1 X11 client-side library ii libxau6 1:1.0.4-2 X11 authorisation library ii libxdmcp6 1:1.0.2-3 X11 Display Manager Control Protoc ii libxext6 2:1.0.4-1 X11 miscellaneous extension librar ii libxi6 2:1.1.4-1 X11 Input extension library ii libxinerama1 2:1.0.3-2 X11 Xinerama extension library ii libxml2 2.7.3.dfsg-1 GNOME XML library ii lsb-base 3.2-22 Linux Standard Base 3.2 init scrip ii lxsession-lite [x-sess 0.3.6-2 a lightweight X11 session manager ii lxterminal [x-terminal 0.1.5-1 desktop independent vte-based term ii metacity [x-window-man 1:2.24.0-2 A lightweight GTK2 based Window Ma ii mrxvt [x-terminal-emul 0.5.3-2 lightweight multi-tabbed X termina ii openbox [x-window-mana 3.4.7.2-3 standards compliant, fast, light-w ii scrotwm [x-window-mana 0.9.5-1 dynamic tiling window manager ii twm [x-window-manager] 1:1.0.4-2 Tab window manager ii wmii [x-window-manager 3.6+debian-5 lightweight tabbed and tiled X11 w ii xfce4-session [x-sessi 4.6.1-1 Xfce4 Session Manager ii xfce4-terminal [x-term 0.2.12-2 Xfce terminal emulator ii xfwm4 [x-window-manage 4.6.1-1 window manager of the Xfce project ii xterm [x-terminal-emul 242-1 X terminal emulator ii zlib1g 1:1.2.3.3.dfsg-13 compression library - runtime Versions of packages gdm recommends: ii dialog 1.1-20080819-1 Displays user-friendly dialog boxe ii gdm-themes 0.6.2 Themes for the GNOME Display Manag ii whiptail 0.52.10-3 Displays user-friendly dialog boxe ii xnest 2:1.4.2-11 Nested X server ii xserver-xephyr 2:1.4.2-11 nested X server ii xserver-xorg 1:7.3+18 the X.Org X server ii zenity 2.24.1-1 Display graphical dialog boxes fro Versions of packages gdm suggests: ii libpam-gnome-keyring 2.26.1-1 PAM module to unlock the GNOME key ii locales 2.9-12 GNU C Library: National Language ( ii pm-utils 1.2.5-2 utilities and scripts for power ma -- debconf information: gdm/daemon_name: /usr/bin/gdm * shared/default-x-display-manager: gdm -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
