I am using Jaunty. I noticed the full screen flash playback is quite choppy and it has already been reported as a bug, solution to the problem has also been posted:

https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/314928/

When implementing the solution, when the last step:

echo "base=0xb0000000 size=0x10000000 type=write-combining" > /proc/mtrr

I keeps getting:

bash: echo: write error: Invalid argument
when trying to edit mtrr file.

Anyone knows why?
