I'm trying to set up a used PC for my 6 year old using Edubuntu 11.10.
My hardware is a P4 2.8 on an Intel D945GNT board.

Now I think that it worked fine at first (but im not sure since the first few things I did was to update the system).
Now what happens is that after clicking a few times on the "Dash Home button" all the UI freeze. I can still SSH or SMB to the machine so its still working in the background.
I have read this:
And I seem to get the feeling that intel GPU is not best suited from Ubuntu.
Maybe I should try and uninstall the updated packages one by one? but I could not find a good method to do it.
Should I replace drivers? If so how?
