In Ubuntu 7.04 I ran Compiz-Fusion in XGL with the fglrx drivers and the system was very responsive. I noticed no performance penalties at all. In Ubuntu 8.04 I am running Compiz natively with the current fglrx drivers, and the system is sluggish. Disabling Compiz makes the system very responsive. So I am interested in running Compiz in XGL like I had in 7.04. Is this advised? Are there and disadvantages? I specifically need the Enhanced Zoom Desktop and Negativity plugins. Thanks in advance.

So disabling xgl will probably work (although the performance may not be as good as xgl in 7.04), either that or you will need to rollback to an older driver and use xgl. Joel
