Answer 1

First uninstall all previously attempted driver intallation by running

sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo apt-get remove --purge fglrx*

If you driver wasn't manually installed then you can skip the first command. Make sure universe and multiverse are enabled in your repository sources by going

(System -> Administration -> Software Sources).

AMD driver needs some prerequisite packages to be installed.

For 32-bit system run

sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev-lts-trusty

For 64-bit system run

sudo apt-get install lib32gcc1

Now downlod the Crimson Driver

mkdir catalyst15.11 && cd catalyst15.11
wget --referer='http://support.amd.com/en-us/download/desktop?os=Linux+x86' http://www2.ati.com/drivers/linux/radeon-crimson-15.11-15.30.1025.zip
unzip radeon-crimson-15.11-15.30.1025.zip
cd fglrx-15.30.1025/

Create and install .deb packages

chmod a+x amd-driver-installer-15.30.1025-x86.x86_64.run
sudo ./amd-driver-installer-15.30.1025-x86.x86_64.run --buildpkg Ubuntu/trusty
sudo dpkg -i fglrx*.deb
