I have Ubuntu Feisty Fawn installed on a partition of my box also (Core 2 Duo). I agree it has come a long way since I used to play with the first versions of Slackware:-D
Take a look at Beryl, it really neat as far as eye candy goes. I have had some trouble with Ubuntu and screen refresh rate selection from the desktop. It really wants to default to 60HZ unless I manually play with the config files. I sort of gave up on it for now, but I always go back and look once and a while. It could be my ancient PanaSync E21 also.
Have fun,
Jeff
