The same error occured on a second system upgraded from F13 to F14. A little digging around in /var/log/gdm showed that there was a problem with a mising library. which led me to https://bugzilla.redhat.com/show_bug.cgi?id=632934. Installing package at-spi2-atk fixes the error, but this is quite puzzling as a previous kernel worked without this library. I am also seeing this same problem, after a yum update 2 days ago on a ThinkPad X201. But I don't think it is a kernel problem but rather a race condition as also reported by another ThinkPad X201 user here; http://lists.fedoraproject.org/pipermail/users/2010-November/386694.html The workaround they found is to press ctrl-alt-backspace which reloads GDM and then it works. The workaround to use a F13 kernel or install at-spi2-atk, likely changes the timings slightly which causes the bug not to trigger. I also have a ThinkPad T410 which the exact same intel chips, both running F14 64bit, and does not suffer from the issue. But the X201 has an SSD which makes it very fast to boot up, which also leads me to believe this may be a race condition. Now the same problem on a third system upgrade from F13 to F14. All different hardware. Robert may be right that the kernel and at-spi2-atk are red-herrings as those work-arounds did not help with the most recently upgraded system. I can confirm that resetting the X server with ctrl-alt-backspace does enable a login through GDM. Same error here on a F14 clean install (x86_64). Here's some GDM output. Happens, consistently, on several systems. ** (<unknown>:2355): DEBUG: Client registered with session manager: /org/gnome/SessionManager/Client1 ** (gnome-settings-daemon:2358): WARNING **: AT-SPI: Accessibility bus not found - Using session bus. ** (process:2376): DEBUG: Greeter session pid=2376 display=:0.0 xauthority=/var/run/gdm/auth-for-gdm-LX2XEz/database (gnome-settings-daemon:2358): GdkPixbuf-CRITICAL **: gdk_pixbuf_format_get_name: assertion `format != NULL' failed Internal error: Could not resolve keysym XF86TouchpadOn Internal error: Could not resolve keysym XF86TouchpadOff gdm-simple-greeter[2376]: Gtk-WARNING: gtkwidget.c:5691: widget not within a GtkWindow Window manager warning: Buggy client sent a _NET_ACTIVE_WINDOW message with a timestamp of 0 for 0x200002b (Login Wind) Window manager warning: meta_window_activate called by a pager with a 0 timestamp; the pager needs to be fixed.
