No worry about your english, it's perfectly fine :)
Ok, so let's try to debug this.
First thing, we need to know if compiz segfault or not in your unity session. Can you please, open a session (so, without any decoration), then switch to vt1 and run:
$ export DISPLAY=:0
$ export COMPIZ_CONFIG_PROFILE=ubuntu
$ compiz --replace 2>&1 | tee compizlog
Then, you should have a compizlog file in your home directory, can you attach it here please?
