Comment 2 for bug 153818

Thanks for your bugreport.

If this machine has a intel i965, then this is expected behavior (also the error message is not ideal because it gives no further explaination). The reason for the blacklisting is that the i965 does no longer have video overlay hardware and the only way to get Xv video working under compiz with this card is to enable the new and experimental EXA acceleration architecture.

It is possible to override this checks by creating:
~/.config/compiz/compiz-manager
and adding SKIP_CHECKS=y

More information can be found in the file ~/.xsession-errors. The blacklist is currently part of /usr/bin/compiz
