Title:
  Unable to unlock gnome screensaver

Status in “gnome-screensaver” package in Ubuntu:
  Expired

Bug description:
  Binary package hint: gdm

  
  Quite frequently, when the screensaver kicks it, the system can not be unlocked.  When returning to the system, only a blank screen is displayed, with no mouse cursor.

  The following line is usually found in syslog:

  Feb 18 10:04:57 ubuntu gnome-session[2140]: WARNING: Detected that
  screensaver has left the bus

  DISTRIB_DESCRIPTION="Ubuntu 10.04.2 LTS" (fully patched)

  
  Current kernel (but this happens with the 2.6.32 series as well):

  beaty@ubuntu:~$ uname -a
  Linux ubuntu 2.6.35-23-generic #41~lucid1-Ubuntu SMP Thu Dec 2 22:30:17 UTC 2010 i686 GNU/Linux

  
  This is a Dell Latitude M6510
