Flash fullscreen doesn't work on Ubuntu 10.10

If you are reading this, its because you have installed Ubuntu 10.10 and found out that flash videos don't play in fullscreen...

we tested Ubuntu 10.10 on several computer and the problem was always present on older computers, specially with laptops using Mobile Intel® 945GM Express Chipset! We could not get fullscreen to work with several website including youtube, hulu, and other popular websites. This was a problem that had nothing to do with the browser because fullscreen did not work on Chrome, Firefox, and Chromium.

The problem has something to do with flash having hardware acceleration enabled
