I'm having issues with my video card drivers: GeForce 9600 GT/PCI/SSE2
When installing Nouveau - not getting 3d support and the 2d is really buggy, fuzzy fonts and lots of other stuff. Really ugly.
When installing Nvidia drivers, getting 3d support, but not 2 monitors. When using nvidia settings, and setting up 2 monitors, X crashes on weird occasions, like opening skype, or VirtualBox... I'm guessing the popup windows killing it... Really weird stuff...

have no idea what else can I do to make this work right.

EDIT: ok, so I've narrowed down the issue. when using just NVIDIA drivers, and empty xorg.conf everything work ok, except dual screens - I get only one screen, and I'm using Nvidia Settings to get it working as dual screens, but when I save the configuration to xorg.conf, after restarting X, I'm back to chrashing on skype etc.

the xorg.conf saved by Nvidia Settings:

user@ubuntu:~$ cat /etc/X11/xorg.conf

# nvidia-settings: X configuration file generated by nvidia-settings

# nvidia-settings:  version 280.13  (buildd@yellow)  Fri Aug  5 12:31:28 UTC 2011
