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
