So, I finally decided to crack out the new Ubuntu release, and the installer seemed to be successfull and it was time to reboot the machine which is where things went terribly wrong. My login screen was a blank screen.

So I then pushed CTRL+ALT+F1 to get to a shell, and noticed that by default the ati opensource video driver in xorg.conf wasnt happy at all.

Section "Device" Identifier "Configured Video Device" Driver "vesa" EndSection Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" EndSection

So after googling a bit, i discoverd that support for this Radeon Series of cards was updated in later releases of the fglrx driver. Which can be enabled in 5 easy steps.

1. Remove all references to the older fglrx driver.

sudo apt-get remove xorg-driver-fglrx fglrx-kernel-source

2.Update the sources list

sudo apt-get update

3. Reinstall the newer drivers

sudo apt-get install xorg-driver-fglrx fglrx-kernel-source jockey-gtk xserver-xorg-video-radeon

4. Enable the fglrx drivers

sudo aticonfig --initial

5. Restart gdm

sudo /etc/init.d/gdm restart

We can now verify that we have the right driver installed by using fglrxinfo. osamad@root:~$ fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 2400 XT OpenGL version string: 2.1.8087 Release

And voila, I then was able to launch the ATI Catalyst Control Center from the menu system Applications > Accessories > ATI Catalyst Control Center , and used that to enable my dual monitors.

After that I enabled the desktop effects and installed the compizconfig-settings-manager sudo apt-get install compizconfig-settings-manager System > Preferences > Compiz Config Settings Manager to enable my desktop cube! And now am a happy camper!
