Hey everybody!
First of all, sorry for my english.

I am not sure if this is an X problem:

If the movies and games you are talking about are on the internet: and you have an opensource flash substitute installed, it may be the problem:

I have noticed gnash crash gnome before on Feisty...I haven't seen it in Hardy yet.

What size is your monitor? The maximum size noted in your xorg.conf file is 1280x1024. Does your regular Ubuntu desktop take up the full monitor space? If so, I don't think the issue is Hardy in general or xorg.conf in particular. It may be the program you are using to run the movies or games, or as BryannPaulaMelvin suggested, it may be a plug-in.
