Recently I upgraded from Ubuntu Intrepid to Jaunty (9.04). Things are great, especially the boot time (my computer boots consistently in 15-20 secs since the upgrade). But somehow since the upgrade flash videos on websites like youtube, hulu etc have had problems with fullscreen view. The video becomes seriously choppy when seen in full screen mode and the usual reinstall of flash plugins didn't seem to make it any better. This was quite annoying especially since this issue didn't exist in Intrepid (8.10) or previous versions of Ubuntu.
After a bit of web search, I finally stumbled on the right solution. The solution, as usual, was on Ubuntu forms in this post and in bugs.launchpad.net here. In short, do "lspci -vv" and find the VGA output. Then find the right address to be added in the file /proc/mtrr. Apparently, the write-combining method of accessing the MTRRs has been affected due to a missing line in /proc/mtrr file. Adding the right range for write-combining lets the graphics card work much better.
I followed this method. Find the 'prefetchable' memory range and substitute in the 'echo' statement to the file /proc/mtrr.
And enjoy watching the daily show in full screen again!

On a tangent, which browser do you use? Firefox is so buggy on Ubuntu.
I use firefox. What bugs are you talking about? E.g., this fullscreen flash stuff was also a bug, which I first thought was related to firefox. But as it turns out it was something else. I have used Opera and Konqueror a few times, but I never grew used to them. Epiphany is too plain and simple for me.
I don't know, it just seemed too unstable. It seems to work better in 9.04 though.
I used Opera for a while and grew like it a lot. I still don't have the heart to leave Firefox though; it just doesn't seem right. And yeah, Epiphany is way too plain.
Dude, the addons are enough reason to stick to firefox :)
On windows, once google chrome has addon support, I will move to chrome.
I have the same problem, but there is a solution, witch works on my computer. Move your mouse pointer just as you have clicked on "full screen" botton rapidly to the down right (may go also with the left :) border of the screen and let it there.
As about Firefox: it is probably less buggy in Ubuntu as non open source browser. Especially with flash videos.
Great solution. Works great now.
Thanks

You've helped solve this issue by promoting the solution for fellow geeks everywhere.
Lol. Yeah I am a big fan of xkcd and I am surprised that Randall (the author of that xkcd) has no been able to solve this issue, especially since I also have an intel card.
Jon Stewart streams quite well to my Ubuntu :)
