I have an AMD 64 x2 and an ATI Radeon X300. Ubuntu 7.10 with all the updates as and when they appear.
I had the desktop effects enabled and working nicely but today, the desktop effects disabled themselves and I got the problem with Xgl using 100% CPU whilst using Firefox, particularly when scrolling.
Desktop effects refused to re-enable.
I disabled the restricted ATI driver and re-booted, then re-enabled the restricted ATI driver and re-booted again. I was then able to re-enable the desktop effects and the Firefox / Xgl problem was cured.
