Package: gdm3 Version: 2.30.2-4 Severity: normal Tags: squeeze I have two monitors, using TwinView, configured with help of "nvidia-settings". My primary monitor is on the left side, and the secondary is on the right side (as the default). When GDM starts, the greeter appears on the secondary (right) monitor, while it's expected to be on the primary (left). Once logged in, the primary monitor selection behaves fine, all the menus and panels stays on the primary monitor as expected. A also have found reports of the same problem on ATI cards.
Apparently it has to do with the mouse position when X starts and the way the greeter chooses the montor on which to show up. As I see it, the greeter is supposed to appear on the monitor where the mouse cursor is, which happen to be placed exactly in the middle of two monitors. The option "XineramaScreen" in /etc/gdm3/custom.conf (as http://library.gnome.org/users/gdm/stable/configuration.html.en suggests) does not seem to correct the problem (they removed Xinerama support from GDM3?). I do not have a solution, but found some workarounds: 1. While X starts, move the mouse to the left. The delay between X starts and the greeters is showed seemes to give enought time for the cursor to move to the correct direction. So when the greeter shows, it is placed on the right (actually, on the left one, sorry) monitor. Can't say it's usable on a regular basis, but I believe this workaround illustrates well the nature of the problem. 2. nvidia-settings utility can create a good xorg.conf example. Between other things, it allows you to specify the respective position of the screens quite precisely. In my case (two 1280x1024 flat screens), the line is: Option "MetaModes" "DFP-0: nvidia-auto-select +0+0, DFP-1: nvidia-auto-select +1280+0" The workaround is to make the screens to overlap at least one pixel: Option "MetaModes" "DFP-0: nvidia-auto-select +0+0, DFP-1: nvidia-auto-select +1279+0" This brakes the thin balance of the cursor position to the right side (actually to the left, sorry again) and the GDM greeter behaves correctly. 3. There is a bug report of the same problem in Ubuntu: https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/395314 Joerg Friede suggestes another workaround which i have not tested, but i see no reason why it shouldn't work. Let me quote: > Another quick workaround (if not already posted somewhere else) that worked for me: > > - install xwit from using apt-install or synaptics > - add the following line to /etc/gdm/Init/Default or another script that gets called by gdm prior to login > > xwit -root -warp 500 500 #or use any other x/y coordinates that lie within the range of the primary monitor > > Hope this helps Thank you. -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/2 CPU cores) Locale: LANG=es_MX.utf8, LC_CTYPE=es_MX.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages gdm3 depends on: ii adduser 3.112 add and remove users and groups ii debconf [debconf-2.0] 1.5.35 Debian configuration management sy ii gconf2 2.28.1-3 GNOME configuration database syste ii gnome-session [x-sessio 2.30.2-1 The GNOME Session Manager - GNOME ii gnome-session-bin 2.30.2-1 The GNOME Session Manager - Minima ii gnome-terminal [x-termi 2.30.2-1 The GNOME terminal emulator applic ii libart-2.0-2 2.3.21-1 Library of functions for 2D graphi ii libatk1.0-0 1.30.0-1 The ATK accessibility toolkit ii libattr1 1:2.4.44-2 Extended attribute shared library ii libaudit0 1.7.13-1+b2 Dynamic library for security audit ii libbonobo2-0 2.24.3-1 Bonobo CORBA interfaces library ii libbonoboui2-0 2.24.3-1 The Bonobo UI library ii libc6 2.11.2-5 Embedded GNU C Library: Shared lib ii libcairo2 1.8.10-5 The Cairo 2D vector graphics libra ii libcanberra-gtk0 0.24-1 Gtk+ helper for playing widget eve ii libcanberra0 0.24-1 a simple abstract interface for pl ii libdbus-1-3 1.2.24-3 simple interprocess messaging syst ii libdbus-glib-1-2 0.88-2 simple interprocess messaging syst ii libdevkit-power-gobject 1:0.9.5-1+b1 abstraction for power management - ii libfontconfig1 2.8.0-2.1 generic font configuration library ii libfreetype6 2.4.2-1 FreeType 2 font engine, shared lib ii libgconf2-4 2.28.1-3 GNOME configuration database syste ii libglib2.0-0 2.24.1-1 The GLib library of C routines ii libgnome2-0 2.30.0-1 The GNOME library - runtime files ii libgnomecanvas2-0 2.30.1-1 A powerful object-oriented display ii libgtk2.0-0 2.20.1-1+b1 The GTK+ graphical user interface ii liborbit2 1:2.14.18-0.1 libraries for ORBit2 - a CORBA ORB ii libpam-modules 1.1.1-6 Pluggable Authentication Modules f ii libpam-runtime 1.1.1-6 Runtime support for the PAM librar ii libpam0g 1.1.1-6 Pluggable Authentication Modules l ii libpanel-applet2-0 2.30.2-1 library for GNOME Panel applets ii libpango1.0-0 1.28.1-1 Layout and rendering of internatio ii libpolkit-gobject-1-0 0.96-2 PolicyKit Authorization API ii libpolkit-gtk-1-0 0.96-2 PolicyKit GTK+ API ii libpopt0 1.16-1 lib for parsing cmdline parameters ii librsvg2-common 2.26.3-1 SAX-based renderer library for SVG ii libselinux1 2.0.96-1 SELinux runtime shared libraries ii libwrap0 7.6.q-19 Wietse Venema's TCP wrappers libra ii libx11-6 2:1.3.3-3 X11 client-side library ii libxau6 1:1.0.6-1 X11 authorisation library ii libxdmcp6 1:1.0.3-2 X11 Display Manager Control Protoc ii libxklavier16 5.0-2 X Keyboard Extension high-level AP ii libxml2 2.7.7.dfsg-4 GNOME XML library ii lsb-base 3.2-23.1 Linux Standard Base 3.2 init scrip ii metacity [x-window-mana 1:2.30.1-2 lightweight GTK+ window manager ii policykit-1-gnome 0.96-2 GNOME authentication agent for Pol ii twm [x-window-manager] 1:1.0.4-2 Tab window manager ii upower 0.9.5-1+b1 abstraction for power management ii xterm [x-terminal-emula 261-1 X terminal emulator ii zlib1g 1:1.2.3.4.dfsg-3 compression library - runtime Versions of packages gdm3 recommends: ii at-spi 1.30.1-2 Assistive Technology Service Provi ii gnome-icon-theme 2.30.3-1 GNOME Desktop icon theme ii gnome-power-manager 2.30.1-1 power management tool for the GNOM ii gnome-settings-daemon 2.30.2-1 daemon handling the GNOME session ii xserver-xephyr 2:1.7.7-6 nested X server ii xserver-xorg 1:7.5+6 the X.Org X server ii zenity 2.30.0-1 Display graphical dialog boxes fro Versions of packages gdm3 suggests: ii gnome-mag 1:0.16.1-2 a screen magnifier for the GNOME d ii gnome-orca 2.30.2-1 Scriptable screen reader ii gok 2.30.0-1 GNOME Onscreen Keyboard ii libpam-gnome-keyring 2.30.3-1 PAM module to unlock the GNOME key ii metacity 1:2.30.1-2 lightweight GTK+ window manager -- debconf information: * shared/default-x-display-manager: gdm3 gdm3/daemon_name: /usr/sbin/gdm3 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
