About a week ago I inserted the Extensions section and not disabled DRI. Since then ubuntu 8.04.1 has worked well. No black screens or freezes. Still get the occasional screen flash but this is rare now. Maybe once an hour, was once a minute. As an aside, I tried the same xorg settings on a recently upgraded sidux. Sidux desktop still black-screens, usually after, or during, a graphical event, like a picture in a web page or running a bbc news video. If I then disable DRI on sidux it is totally unusable; the desktop freezes inside a minute and have to switch VTs to unfreeze. I have run an update on ubuntu and the desktop still seems stable provided I keep the Extensions section that disables Composite. Thanks for the advice.
