Public bug reported:

Binary package hint: x11-xserver-utils


$ lsb_release -rd
Description:	Ubuntu karmic (development branch)
Release:	9.10
$ apt-cache policy x11-xserver-utils
x11-xserver-utils:
  Installed: 7.4+2ubuntu3
  Candidate: 7.4+2ubuntu3
  Version table:
 *** 7.4+2ubuntu3 0
        500 http://us.archive.ubuntu.com karmic/main Packages
        100 /var/lib/dpkg/status


My expectation is that xrandr will recognize the correct maximum 3200x1200 size on my Thinkpad T400 laptop and will allow me to set the size to 3200x1200.  My maximum screen resolution is 3200x1200, and I used this resolution on a dual external monitor setup when docked.  I use xrandr to set up my screen resolution when docked with the following script that, until this morning, has worked just fine:

#! /bin/sh
xrandr --output LCD --off && \
xrandr --fb 3200x1200 \
       --output DFP1 --auto \
       --output CRT1 --auto --right-of DFP1

Within the past three days of updates to karmic (somewhere between
10/9/9 and 10/12/9), the script above stopped working, and the root
cause of this is that the maximum screen resolution as seen by xrandr is
only 2048x2048 instead of the required 3200x1200.  The following is what
xrandr returns when I attempt to set this size:

$ xrandr --fb 3200x1200
xrandr: screen cannot be larger than 2048x2048 (desired size 3200x1200)
