Comment 85 for bug 128803

The reason i was having this problem was that i have the git version of compiz installed in the wrong location '/usr/local/bin/compiz' all i had to do was make a symlink to '/usr/bin/compiz' and boot time was sorted!

Just thought i'd put that out there incase anyone was having similar issues. Thank you to whomever suggested checking the xsession-errors file!
