** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  On a Dell Optiplex SX280 with intel 915G graphics and DVI output to a
  1600x1200 monitor, the login screen graphics only fills the upper left
  1280x800 of the screen. When logging in, the bar that is supposed to be
  on the bottom of the screen (in either KDE or Gnome) therefore appears
  halfway up. Other than affecting the placement of elements relative to
  the bottom of the screen, everything seems to be working fine. This does
  not happen always. Often, when the computer is rebooted, it is fine for
  the first login screen, but it the problem then shows up if the X-server
  is killed with Ctrl-Alt-Backspace.
  
  I attach a screenshot of the login screen (taken from vt2 with 'chvt 7;
  sleep 4; XAUTHORITY=/var/lib/gdm/:0.Xauth DISPLAY=":0.0" import -window
  root importdump.png; chvt 2' as root). Running xserver-xorg-video-intel
  2:2.2.1-1ubuntu13.6.
  
  I have tried with two different displays, Dell 2001FP and 2007FP, with
  the same result. Using the driver "i810" instead of "intel" makes the
  problem go away. So does switching from DVI to VGA.
  
  I will attach a few log files. They are all taken when after the initial
  login screen after boot was fine, and the next had the problem, so the
  ones with "old" in the filename are logs where I saw no problems.
+ 
+ Update: The problem also occurs in Intrepid but the symptoms are
+ slightly different (see comments). The underlying problem seems to be
+ that the driver detects something on the VGA port (which is
+ disconnected) and sets the resolution of the DVI output to match this
+ imaginary VGA display.
