I had a Ubuntu 13.10 with a Radeon HD 3850 using fglrx-legacy drivers, and I was forced to remove them in order to upgrade to Ubuntu 14.04. The 14.04 generic display driver is ok but only provides a software rendering mode. I confirm that the standard fglrx drivers won't work (black screen) with old ATI cards such as the HD2xxx-4xxx series. Once the 14.04 installed you can try to install fglrx-legacy drivers with those commands (worked for me on 13.04+, not tested yet on 14.04) or via Synaptic: sudo add
