Hi Tha1 and welcome to Arch.
I can suggest to you the following advices.
First install these packages:
hal
xf86-input-evdev
start hal under root with:
/etc/rc.d/hal start
and to have it started at each reboot:
add hal at the end of the DAEMON line in /etc/rc.conf file
Have a minimal xorg.conf file:
Code:
Section "ServerFlags"
Option "DontZap" "False"
EndSection
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
EndSection
That should be enough with the last xorg-server 1.6.1 release.
Restart Xorg.
Try that and tell if that works for you, if not try to post the /var/log/Xorg.0.log file.
Good luck.
