I can not see the similarities but probably someone others may confirm this if I attach some more information. I note that after the latest packages (Feb 26, 2010) this issue still exists.
I have an mgag550 card and seemingly no any issue with X. Please, find attached the /var/log/gdm/:0.log file and I copy here the /var/log/gdm/:0-greeter.log which shows some more strange messages: Window manager warning: Failed to read saved session file /var/lib/gdm/.config/metacity/sessions/10f7468eb92810ebff126718502788503500000014400006.ms: Failed to open file '/var/lib/gdm/.config/metacity/sessions/10f7468eb92810ebff126718502788503500000014400006.ms': No such file or directory ** (process:1454): DEBUG: Greeter session pid=1454 display=:0.0 xauthority=/var/run/gdm/auth-for-gdm-jk9bSG/database gdm-simple-greeter[1454]: Gtk-WARNING: /build/buildd/gtk+2.0-2.19.6/gtk/gtkwidget.c:5634: widget not within a GtkWindow Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x1400024 (Login Wind) Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.
