After a spell on windows 7 I'm back with ubuntu

the main reason for my stay away was GPU acceleration in flash ( I have a tiny intel atom processor but a reasonable GeF. 9300M GS so it's a big thing )

Now it's here on linux for NVidia with vdpau and highly recommended. Simply install vdpau and the latest flash beta (10.2). Assuming your card supports it and your using the proprietary drivers

sudo apt-get install vdpau-va-driver

The flash is available here

download the linux version and extract the to /usr/lib/mozilla/plugins/ for firefox

Now right clicking on a flash video and clicking "about adobe flash player" should show the version as 10.2......

You should also be able to view youtube videos in 1080p without your CPU breaking a sweat.

That's the how to, next post for the question.
