Comment 43 for bug 445056

I am the original reporter of the on Launchpad. Everything posted above by Petar and Marco is consistent with my experience.

I wold like to add two points that may be useful. First, I have discovered that when compiz is started with the --indirect-rendering flag, the freeze does NOT occur and the video driver functions with no problem.

Also, to clarify on EXA acceleration issue: I originally stated in the Launchpad bug report that adding 'Option "AccelMethod" "exa"' to xorg.conf solved the problem. I later realized this was not the case--the X server still ended up freezing shortly after I made that comment in the bug report--and furthermore that according to the Xorg.0.log, the "AccelMethod" option was not even recognized when X started (presumably this option has been deprecated by X in the latest version of Ubuntu; it used to be valid). So I assume that editing my xorg.conf file didn't actually do anything and there is currently no reason to believe that enabling EXA acceleration solves the problem. I apologize for the confusion about this.

Please let me know if I can provide any other pertinent information.
