BTW:I don't think it'll help, but perhaps you should add your cards BusID to xorg.conf.
DO NOT CHANGE ANY THING BESIDES ADDING THE CODE IN RED. BUT READ THIS POST ALL THE WAY THROUGH BEFORE PROCEEDING.
Ok open up xorg.conf in super-user mode
Edit your file so it matches the one below.
we will only be changing the code in red.
Other parts in this file may not look like yours. This is because I got mine from a machine using an intel graphics card
# xorg.conf (X.Org X Window System server configuration file)
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
Identifier "Configured Video Device"

Device "Configured Video Device"
On the BusID "PCI:01:05:0", yours needs to be a little different.
To find out your BusID open terminal and type:
You will get an output kinda like
Type your version of the number in red in the BusID SubSection (CAPS sensitive)
01:05.0 VGA compatible controller: ATI Technologies Inc RS690M [Radeon X1200 Series]
but a little changed so that if you got the number:
it would look like
"PCI:01:05:0"(and of course the quotes)
note the adding of PCI: and that the . after 05 is replaced with :
BTW: sorry if this posts format sounded a little wierd. I just copied it off of another post of mine (different thread) and edited it a little to be more relevant.
