Comment 53 for bug 199960

Sebastien, IIRC, I believe that Compiz is enabled by default since Gutsy. If Compiz is not stable in any scenario (with our without xserver-xgl), then Compiz should be disabled by default and big warning sign should show up whenever a user enables it, stating that Compiz is experimental. Hardy Herons is an LTS release and above all, it should be stable when installed with defaults. Should we change the title and description of this bug report to have Compiz disabled by default? At least for the video cards for which Compiz is known to be unstable?

BTW, I believe I inadvertently installed xserver-xgl, thus it probably does not show up in a fresh install. Currently, I have Compiz working without xserver-xgl on an Intel GM965/GL960 and seen no stability problems. But I have not played much with the test machine either. I believe that the problem reported might be only related to some video drivers, but I cannot confirm this.
