sudo aticonfig --initial
sudo gedit /boot/grub/grub.cfg

Run those in a terminal before rebooting and add nomodeset to the end of the kernel string in your GRUB configuration file. Kernel string looks like this.

linux	/boot/vmlinuz-3.x.x-x-generic root=UUID=UUID ro   quiet splash

Also, I suggest using the open source ATI driver. It's a lot smoother than fglrx and Catalyst.

sudo apt-get install xf86-video-ati

If that doesn't work (I'm not an Ubuntu user, so I don't know what's in their repos), try the following.

cd
git clone git://anongit.freedesktop.org/xorg/driver/xf86-video-ati
cd foldername
./configure && make
sudo make install clean

It might require a different compilation method, but that's the gist of it. Ubuntu has documentation on their site for ATI cards.
