I had the same result, but I got it to work. Instead of the Ubuntu packages, get the generic "Linux (32-bit & 64-bit)" which is 148 MB zip file. Unzip and then sudo ./amd-driver-installer-14.501.1003-x86.x86_64.run
. Choose to build packages for Trusty. It takes several minutes and doesn't seem to be doing anything, but just wait for it.
Then when I tried sudo dpkg -i *.deb
with the resulting files it told me there was a conflict so I had to do apt-get remove ocl-icd-libopencl1:amd64
before it would work. But then the 4 .deb files installed without error.
sudo aticonfig --initial and reboot. flgrxinfo now reports:
display: :0 screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.

Seems to work but the catalyst control center won't start.
Edit: I tried Counter Strike in Steam and it ran very smooth. Much better than before but I think I had a broken driver install before.
Edit2: My chrome://gpu/ used to show all red / disabled and now only "Multiple Raster Threads" is disabled. Everything else is green. Full screen 60fps youtube is buttery smooth with no tearing.
Edit3: download separate amdcccle.deb package from amd site and reinstall it with Gdebi or Software centre, then Catalyst Control Cetntre will start.
sudo dpkg -i *.deb
in that directory to install them. – dobey Dec 09 '14 at 20:49
