Gonzo has been reborn!
My trusty old Thinkpad has finally died and so I have brought a Fujitsu A531 to replace it. Its not a bad spec for the money I paid (i3 2.2, 8gb, 750gb HDD all for £419).
I have just installed Arch 64 bit on it and had KDE up and running in less than an hour and a half. The first thing I noticed was the graphics acceleration was not enabled and I seemed to be suffering poor framerates. I found that by adding a file called 20-intel.conf to the /etc/X11/xorg.conf.d directory and adding the following solved my issues :
Section "Device"
Identifier "Card0"
Driver "intel"
Option "DRI" "true"
Option "SwapbuffersWait" "false"
EndSection
Reboot and 3D effects and a good framerate where restored.
