I just installed FC15 on a machine with a very fast and modern CPU. I'm running GNOME 3.
Often times, but not always, when when I type simple text at the command line, it takes as much as 5 seconds for the characters to appear on the screen. This makes it very difficult to use. Why is this happening and can I do anything to fix it?
Also, sometimes simple commands, like trying to close a window take 5 seconds, sometimes they happen instantly. What's going on here?
