Thanks TobiSGD; I did as you said and did these commands and got the drivers and the Catalytic Control Bur still can't do VGA 1 1204x768 and DVI 1920x1080 resolution there is no other option then clone or mirror.i also notice VGA signal is better than HDMI so i use the VGA for monitor 1.
sudo /usr/share/ati/fglrx-uninstall.sh # (if it exists)
sudo apt-get remove --purge fglrx*
As a further measure I also check what else is left
dpkg -l '*fglrx*'
I also make sure I have a correct set of open source drviers installed
sudo apt-get remove --purge xserver-xorg-video-ati xserver-xorg-video-radeon
sudo apt-get install xserver-xorg-video-ati
sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg
I then rebuild the the proprietary fglrx/Catalyst driver to be installable through the Restricted Hardware Driver Manager (a.k.a. jockey)
sudo apt-get install fglrx-modaliases
After these have all been completed I reboot and now the open source drviers are working AND xserver-xorg has bene rebuilt I reinstall fglrx
sudo apt-get install fglrx
