my setup is this:
A8N-SLI + AMD64 3800 + MSI Geforce 6600 GTOC + Linksys Wireless G Pci card
I'm currently using Ubuntu
http://www.ubuntulinux.org
download the hoary 5.04 version (preview as of today) i.e. hoary-preview-install-amd64.iso
it comes with the latest nvidia drivers...
at the boot prompt type "expert", this gives you the most control of the install
then, after it's finished installing, the xserver will crash and send you to the tty1 prompt...
login as root and :
#apt-get install nvidia-glx
then run:
#nvidia-glx-config
then restart the xserver:
#/etc/init.d/gdm stop
restart the server:
#gdm
and you should have gnome 2.10 running in full 3D+64 bit
if you want KDE, use synaptic and install the Kubuntu packages
some usb devices will refuse to mount b/c of some nforce4 problems but you can get around that with:
#modprobe --remove ehci_hcd
ALSA is a pain... honestly i can't remember what i did, but after much work i finally got it working...
most of my problems come from the kernel... but the final freeze of ubuntu hoary should take care
of that on April 6.
in order to get 32 bit apps working (cedega, flash player, etc...) there are 2 options...
this is the best
article
i've read on both options
most help with ubuntu can be googled (of course) or found @
