Based on the description of the symptoms, it sort of sounds like this
might be caused by an incorrect AGPMode setting, which is relevant when
DRI is enabled.  Is your system AGP?  I notice the ati-agp kernel module
appears to be loaded which makes me wonder if it's the case.  You should
test if changing this makes the issue go away.  In your
/etc/X11/xorg.conf set AGPMode to various values like this:

 Section "Device"
    ...
    Option "AGPMode" "2"
 EndSection

Possible values include 1, 2, 4, 8.  You can see what it's currently set
to by looking in /var/log/Xorg.0.log.  It's worthwhile to test all four
values even once you find one that works.  If this takes care of it for
you, we may be able to establish a quirk to set it for your hardware
combo, if you can provide the following data:

   * AGPMode value(s) that work
   * Make/Model of laptop or motherboard
   * Output of lspci -vvnn
   * Is the system all factory hardware, or have any parts been replaced?
   * Is there an AGP Mode in the system BIOS?
     - If so, is it set to the factory default?

For more details on this, please see the "ATI AGP Mode Quirk" section at
https://wiki.ubuntu.com/X/Quirks

Also, you might need to disable KMS in order to do the above quirking
(I'm not certain).  For guidance on how to do this, please see
http://wiki.ubuntu.com/X/KernelModeSetting .

** Description changed:

  Binary package hint: xserver-xorg-video-ati
  
  I'm the supplier of bug https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/551678
  I've tried the hints by "Bryce Harrington  wrote on 2010-04-02: ", fully removed every -fglrx / nvidia relevant and reinstalled -ati from scratch. But problems keep the same:
  
  Hardware: Acer Aspire E500 EB7S, video card ATI Radeon X700 SE (dual
  head, left screen 1280x1024 via DVI, right screen 1024x768 via VGA)
  
  After an dist-upgrade to lucid screen output gets weird and unreadable.
  Keyboard and mouse are available and seem to work properly, the cursor
  is painted correctly. After entering user id and password, I get logged
  in, however, the gnome desktop is also weird and unreadable (xfce is the
  same). It is possible to launch applications by clicking on the icon
  location or by ALT+F2. However they are exhibiting the same problem.
  
  With CTRL+ALT+F1 I get a workable text terminal login.
  
  Please see the screenshot.
