Problem:
  • GPU performance is sub par after install AMD 13.1 Drivers.
  • All three monitors show up as 'disabled' in Catalyst.
  • They won't rotate (I have 2 turned 90 degrees).
  • There is pretty bad tearing when moving windows.


About the system:
  • kali-linux-1.0.3-amd64 installed to SSD.
  • HD7970.
  • Fully updated.



I installed my drivers this way:
deb http://ftp.debian.org/debian experimental main non-free contrib

apt-get update

sudo apt-get -t experimental install fglrx-driver fglrx-control

sudo apt-get -t experimental install amd-opencl-icd

aticonfig --initial -f

reboot

Make sure to comment out the experimental repo after you have fglrx working!

FIX: This fix is for AMD/ATI only!
