Recently purchased a Sony VPCCW17FX laptop that is equiped with an nVidia 220m graphic chipset. Not a fan of Windows 7 so I installed Ubuntu 9.10 without a problem.
However to take advantage of nVidia and have all the bells and whistles I needed to update the /etc/X11/xorg.conf file. There were several issues generating via X -configure. First was the xorg.conf file when tested would come up with a blank screen. The second was getting the monitor timings correct.
I found this helpful post on nVidia forums and have to give credit to egghead3!
Anyway, to make life easier for everyone I figure I would post the files needed to make nVidia shine on the Sony laptop. If you are not using a VPCCW17FX this might not work but check the post mentioned above on how to set up your nVidia 220m
Download xorg.conf and SNY05FA.bin and place them in /etc/x11 directory. Make sure you backup your old xorg.conf file if you have one.
UPDATED: Fixing wireless issues with Ath9K driver.
There is a a bug with straight 2.6.31 kernel install with the wireless driver and it will drop the connection during reauthentication. The following will correct this problem with 9.10 Ubuntu
sudo apt-get install linux-backports-modules-karmic linux-backports-modules-wireless-karmic-generic
