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!
