"For the past 33 years, I have looked in the mirror every morning and asked myself: "If today were the last day of my life, would I want to do what I am about to do today?" And whenever the answer has been "No" for too many days in a row, I know I need to change something...almost everything - all external expectations, all pride, all fear of embarrassment or failure - these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose." -- Steve Jobs

Because SONY has modified BIOS for the Nvdia chip in VAIO, official Nvidia drivers can't drive built-in LCD correctly on Ubuntu 10.10. To make LCD usable, one need to:
1. Use the latest Nvidia graphic driver from X updates PPA (260.19.29/270.18 is tested).
2. Modify /etc/X11/xorg.conf to add the two lines to the "Device" section:
Option "ConnectedMonitor" "DFP-0"Option "CustomEDID" "DFP-0: /proc/acpi/video/IGPU/LCD0/EDID"
With these two steps, LCD should work well. Additional external monitors can be added. Also, support of brightness control can be added. Following are my xorg.conf:
Since Ubuntu updates binary drivers infrqeuently, one can update them from the X Updates PPA. Just use these commands:
$ sudo add-apt-repository ppa:ubuntu-x-swat/x-updates$ sudo apt-get update
Then you can get stable release of X.org components, drivers from upstream. Please be aware that those packages are not supported by Ubuntu. Nextly, if you have installed the binary driver for an Nvidia card, you can just type:
$ sudo apt-get upgrade
to upgrade it. Otherwise you can use the "Additional Drivers" tool or just type:
$ sudo apt-get install nvidia-current
to install it. If CUDA/OpenCL headers are also needed, they can be installed by executing this command:
$ sudo apt-get install nvidia-current-dev
After installing all Nvidia packages, a GPGPU (OpenCL/CUDA) development environment is established successfully.
PS: You may need to manually delete some files/links from old version of drivers under the /usr/lib directory.

To make DirectShow works, you can use win7dsfiltertweaker to disable formats support of the Media Foundation Framework (E.g.: MP4). This is a workaround, actually.
